045487946955FFA10FD0FEFBFBCAFE02.taxon	diagnosis	Differential diagnosis. The subgenus Gelaeus can be immediately recognized by the subtriangular, deep and sharply cut basal impression on each side of pronotum situated approximately at 1 / 7 width, while other subgenera of Chrysodema do not have this impression. Additionally Gelaeus also has the aedeagus with broad and parallel-sided parameresseparated by a deep cleft, while species of the other subgenera have mostly narrow parameres with shallow cleft, or broad parameres converning from the middle towards apices.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

045487946955FFA10FD0FEFBFBCAFE02.taxon	distribution	Distribution. Indonesia: Lesser Sunda Islands and Selayar Islands;? East Timor. Gelaeus is found all over Lesser Sunda Islands (ca. 6 ° – 11 ° S a 116 ° – 132 ° E, Fig. 72), however it has not been recorded so far from several larger islands of the archipelago (i. e. Bali, Sumba, Sumbawa, Sawu, and Rote). Nevertheless these islands are poorly explored regarding their insect fauna and some species of Gelaeus might be found there in the future. East Timor is mentioned with a question mark as we mostly have only historical material localized as just Timor without precise locality data.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

045487946955FFA10FD0FEFBFBCAFE02.taxon	discussion	Remarks. WATERHOUSE (1905: 584) stated the following about Gelaeus: ‘ Closely allied to Chrysodema, but differs from all the species of that genus in having two sharply cut impressions at the base of the thorax. Just below the shoulders the elytra are acutely angular. The tarsi are yellow. ’ However, only the sharp cut basal impression on the pronotum is diagnostic as the two other characters are present also in other species of Chrysodema. The acutely angular elytra below humeral calli are also present e. g. in C. (C.) mniszechi Deyrolle, 1864 or C. (C.) aurofoveata (Guérin-Méneville, 1830), the latter being currently considered a junior synonym of C. (C.) radians (Guérin-Méneville, 1830). It is true that all species of Gelaeus have an acute subhumeral protuberance, however, it displays also great intraspecific variation and is often very small. Most species of Gelaeus have yellow tarsi but some have metallic tarsi (e. g. C. (G.) iris moluensis Novak, 2010). Additionally two other species, C. (G.) florensis Lansberge, 1880 and C. (G.) cyanicollis Kerremans, 1900 here assigned to Gelaeus, were placed among Chrysodema s. str. but some authors pointed that they have typical characters of Gelaeus, however rerained them in the nominotypical subgenus (KERREMANS 1909: 527; LANDER 2003: 17 – 18).	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

04548794695EFFA30F51FDABFD10FDA2.taxon	discussion	Remarks. KERREMANS (1898) gave ‘ Macassar’ as the type locality of C. (G.) cupriventris and did not mention how many specimens he had at his disposal, however, he gave a range of lengths: ‘ Long., 21 - 28; larg., 7 - 9 mill. ’ thus he must have had at least two specimens. Later on, KERREMANS (1903) mentioned ‘ Iles Alor et Dammer’ as distribution of C. (G.) cupriventris. We have located two specimens labelled as types with Kerremans original label in BMNH. One has the locality Alor, measures 30.75 × 11.25 mm and does not agree at all with the primary description therefore we exclude it from the type series of C. (G.) cupriventris. The specimen is here included as paratype of C. (G.) walkeri rejzeki subsp. nov., see remarks under that taxon. We believe that it is a voucher specimen for the record published by KERREMANS (1903). The other specimen is curiously small female with somewhat distorted elytra but agrees well with the primary description as well as with the type locality. We found one more specimen from Macassar labelled as type of C. (G.) cupriventris in the collection of Kerremans (MNHN). The specimen perfectly agrees with the primary description therefore we consider the two specimens from Macassar syntypes. The type locality given by Kerremans is peculiar because Macassar is usually understood to be the city in southern Sulawesi. However, in our opinion it is very unlikely that the species lives on Sulwesi as no other species of Gelaeus is know from that island. There is also Pante Macassar in the Oecusse exclave of East Timor in the Indonesian (West) Timor which is a more likely explanation of the type locality. However, as we have not seen any other specimen of C. (G.) cupriventris from Timor mainland we think that the type locality is erroneous. We have examined a series of specimens from the Wetar Island, which perfectly matches syntypes, with exception of uniformly brown tarsi (last tarsomere metallic in syntypes). On the other hand, C. (G.) cupriventris is morphologically most similar to C. (G.) katka sp. nov., which has about half of specimens with metallic tarsi and half with brown tarsi. Thererefore we assume that this character is subject to intraspecific variation in these two taxa. Chrysodema (G.) katka is endemic to Timor and all specimens have densely punctate lateral sides of abdominal ventrites II – V while all specimens of C. (G.) cupriventris have them very sparsely and finely punctate. This character is constant in the series of specimens from Wetar and thus we think this species is maybe restricted to the Wetar Island and was given the locality Macassar because the original type specimens were received through the relatively nearby Pante Macassar, which served as an important port.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

04548794695CFFA20F4DFD24FEE6F9C2.taxon	diagnosis	Differential diagnosis. Chrysodema (G.) cyanicollis belongs among species with distinctly dichromatic dorsal side having pronotum brighter coloured than elytra, latter in tones of green or blue. All similar taxa (C. (G.) walkeri, C. (G.) sara sp. nov., C. (G.) katka sp. nov. and C. (G.) cupriventris) differ in pale coloured tarsi, at most with terminal tarsomere metallic while C. (G.) cyanicollis has tarsi uniformly metallic green. The uniformly green specimen (from Lembata Is.) of C. (G.) cyanicollis is also very similar to C. (G.) florensis as both have metallic tarsi and distinct lateral impressions on elytra. It can be distinguished by lateral sides of abdominal ventrites II – III variously punctate with large impunctate areas (Fig. 4) while C. (G.) florensis has them densely and uniformly punctate without impunctate areas (Fig. 5).	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

04548794695CFFA20F4DFD24FEE6F9C2.taxon	discussion	Remarks. KERREMANS (1900) described Chrysodema cyanicollis from the collection of Meyer Darcis and explicitly mentioned only a single female specimen with size ‘ Long., 26; larg., 8,5 mill. ’. The latter collection was purchased by Julius Moser and is nowadays deposited in MFNB. The holotype is however somewhat larger (27.0 × 9.5 mm) than indicated in the original description. Nevertheless, we consider it as a mistake as the specimens otherwise perfectly fits the original description. Chrysodema (G.) cyanicollis was until now placed in the nominotypical subgenus, however, it posses deep triangular basal impression of the pronotum typical for Gelaeus and therefore we assign it to the latter subgenus. The uniformly green specimen from Lembata resembles C. (G.) florensis, however, in our opinion it is morphologically more similar to C. (G.) cyanicollis despite considerable geographic separation. More specimens from Selayar Islands and Lembata Island are necessary to verify its identity.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

045487946942FFBE0F7DFC03FF5CFC42.taxon	diagnosis	Differential diagnosis. Chrysodema (G.) florensis can be easily separated from the other taxa by elytra with large lateral impressions in combination with dense punctation of elytra. The only similar species is C. (G.) foraminifera, which however differs in the mostly yellow tarsi with only last tarsomere metallic (completely metallic in C. (G.) florensis) and posterior lateral impression elongate or if round then divided into two. Other taxa of Gelaeus have either the lateral impressions of elytra barely indicated or they are absent entirely. However we have examined a single uniformly green specimen of C. (G.) cyanicollis, which has small but distinct lateral impressions on elytra and green tarsi and thus is superficially very similar to C. (G.) florensis. However, it can be separated at once by lateral portion of abdominal ventrites II – III variously punctate with large impunctate areas while C. (G.) florensis has lateral portions of respective ventrites densely and uniformly punctate without impunctate areas.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

045487946942FFBE0F7DFC03FF5CFC42.taxon	discussion	Remarks. LANSBERGE (1880) described Chrysodema florensis but did not mention the number of specimens he had at his disposal or where they were deposited. However, he gave range of lengths and mentioned male and female, therefore he must have had at least two specimens. The collection of Lansberge was purchased by R. Oberthür (nowadays in MNHN) and some duplicate specimens are also deposited in IRSN, collection of J. Neervoort van de Poll (purchased by A. Théry and nowadays in MNHN), and Museo Civico di Storia Naturale Giacomo Doria, Genova (HORN & KAHLE 1935, 1936). We consulted the respective museums and have located two specimens in MNHN (ex coll. R. Oberthür), one having original identification label by Lansberge. LANSBERGE (1880) stated: ‘ Long. 12 – 15, lat. 5 – 6 mill. ’, however, the actual size of the specimens is 25 mm in male and 30 in female. As both fit well the original description except of the size of body we consider them syntypes and suppose that the small size printed in description is the result of an error. We designate the male specimen a lectotype to conserve the status of this species for the purpose of this revision and avoid any further misinterpretation as additional specimens might exist.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

045487946941FFB00F6BFC04FC6AF9C2.taxon	description	Redescription of lectotype. Well preserved ♀ specimen missing only mid last tarsomeres with claws and slightly open elytra with exposed wings. Length 25.25 mm, width 9.50 mm, length / width ratio: 2.66. Body generally metallic green. Pronotum slightly lighter green and somewhat shinier than elytra, basal and principal impressions golden with slight traces of copper. Elytra including elevated ribs uniformly dark green, lateral impressions slightly paler and with slight copper reflections (Fig. 9). Ventral parts bright metallic green with golden reflections (Fig. 10). Legs bright metallic green, tarsi brown, last tarsomere including claws metallic green. Pronotum laterally densely and coarsely punctate, centrally sparsely punctate. Punctures on lateral sides foveolate, more deeply impressed. Medial line well defined, impunctate but not elevated.

Principal impressions round, moderately deep, more or less distinctly separated from disc, densely punctate. Surface between medial and principal impressions with sparsely dispersed punctures basally with larger impunctate areas. Lateral impressions moderate with several large punctures. Basal impressions moderate, oval. Elytra distinctly punctate-striate, puncture rows posteriorly irregularly double or triple. Intervals basally slightly elevated, ca. 4 × wider than puncture rows, impunctate; apically partly obscured due to punctation. Punctation of elytra overall moderate and dense (except on intervals), distance between punctures mostly larger than diameter of the punctures. Puncture rows V – VIII in mid third of elytra arranged in small groups of 2 – 4 separated by impunctate spaces not forming elevated reticulations. Each elytron with two oval lateral impressions situated between weakly visible 6 th and 8 th intervals in basal third and two thirds respectively (Fig. 11). Mid femora in central part strongly shiny, sparsely punctate, punctures large; on sides with densely arranged small punctures. Ventral side of body (Fig. 10) overall coarsely and very densely punctate, only central parts of thoracic and abdominal ventrites sparsely punctate. Whole lateral side of abdominal ventrite I densely and coarsely punctate. Ventrites II – V gradually less punctate apically with small and dense punctation restricted to basal half. Variation. Body ♂ (n = 2) length: 25.00 – 26.25 mm, width: 9.00 – 9.50 mm, length / width ratio: 2.76 – 2.78; ♀♀ (n = 12): length: (23.00) 25.00 – 31.75 mm, width: (8.50) 9.25 – 12.25 mm, length / width ratio: 2.55 – 2.77. Body colouration always basically green, in some specimens with strong copper or turquoise sheen on most of the body. Medial pronotal impressions in some specimens shallowly impressed, principal impressions from round to oval and variably deeply impressed, lateral impressions punctate to impunctate, basal impression oval to triangular. Lateral impressions on elytra present in all examined specimens and of rather constant size. Two specimens have posterior lateral impressions enlarged, occupying width between 4 th and 8 th interval, round and more or less divided into two impressions. One specimen has similarly enlarged posterior lateral impressions and additional oval impressions internally next to it and two small round impressions in centre of elytron in basal third length. Tarsi laterally with metallic spots in four specimens. Aedeagus (Fig. 57) (n = 2) length: 6.68 – 6.94 mm, width 1.43 mm, length / width ratio: 4.67 – 4.85. Apices of parameres rounded.

045487946941FFB00F6BFC04FC6AF9C2.taxon	diagnosis	Differential diagnosis. This species can be separated from similar C. (G.) florensis by pale colouration of tarsi (all tarsomeres green in the latter species) and by lateral portion of abdominal ventrites II – III variously punctate with large impunctate areas (Fig. 4) while C. (G.) foraminifera has lateral portions of respective ventrites densely and uniformly punctate without impunctate areas (Fig. 5). The curious uniformly green specimen of C. (G.) cyanicollis differs by the green tarsi and coarser sculpture of elytra. Some specimens of C. (G.) foraminifera with apparently differently coloured pronotum and elytra are quite similar to C. (G.) cupriventris, which differs in the elytra always lacking lateral impressions (with two impressions in C. (G.) foraminifera), red underside (predominantly green in C. (G.) foraminifera) and in lateral portions of abdominal ventrites II – IV with band of denser but yet sparse punctures along anterior margin while the rest is nearly impunctate (very densely punctate basally and sparsely apically in C. (G.) foraminifera).	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

045487946941FFB00F6BFC04FC6AF9C2.taxon	discussion	Remarks. LANSBERGE (1879) did not state how many specimens he had at his disposal when describing Chrysodema foraminifera nor mentioned any depository. However, he gave a range of lengths: ‘ Long. 25 – 30 millim. ’ thus he must have had at least two specimens. The collection of Lansberge was purchased by René Oberthür (nowadays in MNHN) and some duplicate specimens are also deposited in IRSN, collection of J. Neervoort van de Poll (purchased by A. Théry and nowadays in MNHN), and Museo Civico di Storia Naturale Giacomo Doria, Genova (HORN & KAHLE 1935, 1936). We have searched above mentioned museums as well as other collections and found only a single specimen labelled as type in RMNH. The specimen came from Lansbergeʼs collection, bears handwritten label, but not by Lansberge (H. Huijbregts, pers. comm.), with name and additional small red label ‘ Type’. The specimen agrees with the primary description and thus we assume it is a part of the type series. Since there is possibility of existence of additional type specimens we designate the RMNH specimen the lectotype in order to fix the identity of this species. The lectotype is the only specimen of this species known to us from Flores. We have examined additional eleven specimens morphologically identical to the lectotype but these were collected on Timor. This is quite strange as collectors collected extensively in the past on both, Flores and Timor, but there is no other specimen of C. (G.) foraminifera from Flores. Therefore we assume that the type locality might be erroneous and the species is in fact restricted to Timor but this need to be verified by recent material from Flores. One specimen bears locality data as ‘ Macklot / Poeloe / Samoe’, however, we think it is very unlikely that the specimen was collected in Samoa as H. C. Macklot never visited Samoa but collected in New Guinea, Timor and surrounding islands (EFFERT 2008: 132). Poeloe is an old transcription of pulau which means island (s). Samoe in our opinion is most likely misspelled Semau Island situated at southwest end of Timor Island. Since we do not have actual proof whether the specimen was collected on the latter island or not we list Semau Island with a question mark and the record has to be verified by additional specimens. LANDER (2003: 70) briefly mentioned C. (G.) foraminifera and noted that it appears to be a variety of C. (G.) walkeri with white spots but did not propose any synonymy.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

Length 28.00 mm, width 9.50 mm, length / width ratio: 2.95. Head, pronotum, ventral side and legs except tarsi fern green with purple reflections, the latter particularly obvious on impunctate parts of pronotum and abdomen (Fig. 13). Tarsi yellow, last tarsomere metallic green. Elytra iridescent, purple on top of disc and basally, changing laterally and apically to fern green, then golden, red, violet, blue and finally turquoise (Fig. 12). Pronotum in general moderately strongly and sparsely punctate, only laterally punctures more densely arranged. Medial line well marked, impunctate, appearing slightly elevated. Medial impressions distinctly impressed, moderately deep, sparsely punctate, punctures in basal 2 / 3 smaller and arranged in an irregular row and partly grouped together, in anterior 1 / 3 impressions shallower with punctures almost equal in size to remaining punctures along anterior margin. Principal impressions large, round, bordered internally by row of very fine punctures, centrally and externally smooth with only a few larger punctures. Basal impressions large, oval, broadly open and connected with principal impression. Lateral impressions deep and impunctate. Elytra without lateral impressions, moderately strongly punctate. Punctures small, shallowly impressed basally, and moderately impressed laterally. Rows visible from base to apex, weakly impressed, generally regularly arranged, and irregularly double in apical half. Punctures in rows V – VIII in middle third of elytra quite regularly and sparsely arranged, forming distinct rows not isolated groups, laterally somewhat less regular; spaces much broader than puncture diameter, flat not reticulate (Fig. 14). Intervals basally flat, not elevated, broad, approximately 5 – 6 × as wide as rows of punctures, impunctate; apically and laterally barely elevated and nearly impunctate. Mid femora in central part strongly shiny, sparsely punctate, punctures large, on sides punctures smaller and dense. Ventral side of body (Fig. 13) overall coarsely and quite densely punctate, only central parts of thoracic and abdominal ventrites sparsely punctate.

04548794694CFFB20F33FF64FD9EFB62.taxon	discussion	Remarks. KERREMANS (1898) did not mention explicitely how many specimens he had at his disposal just gave a single length and width measurement: ‘ Long., 28; larg. 9 mill. ’ and stated that the material is from collection of Meyer Darcis. The latter collection was purchased by Julius Moser and is nowadays deposited in MFNB. We have found a single specimen in the latter collection, however since Kerremans did not mention the number of specimens it is not certain that this is the only existing specimen used in making the description. Therefore we designate the MFNB specimen a lectotype in order to conserve status of this species and avoid any further misinterpretations. KERREMANS (1898) gave ‘ Banda’ as the type locality. There is only one other known specimen with the same locality data on handwritten label by J. Obenberger (deposited in NMPC). There is also one specimen with the label Kai Islands. The remaining seven studied specimens were collected on Tanimbar Islands, however, without more precise locality data. Nevertheless we assume that the type locality Banda Island as well as the record from Kai Island are erroneous and the species is restricted to Tanimbar Islands because all specimens are quite similar each to other, not displaying much variation and on the Tanimbar Islands also occurs C. (G.) iris moluensis the other subspecies of this taxon. Therefore we change the type locality to Tanimbar Islands. More accurately localized material is needed to confirm and clarify the distribution of this species.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

Punctures in rows V – VIII in middle third of elytra quite regularly and densely arranged forming distinct rows not isolated groups, laterally somewhat less regular; spaces slightly broader than puncture diameter, flat not reticulate (Fig. 17). Intervals more or less convex from base to apex, moderately broad, approximately 3 × as wide as rows of punctures, nearly impunctate, only with a few coarse punctures apically. Mid femora and ventral side as in nominotypical subspecies (Fig. 16). Aedeagus (Fig. 59) length 6.63 mm, width 1.38 mm, length / width ratio: 4.80. Apices of parameres truncate. Penis oval, distinctly rounded on sides. Variation. Body ♂♂ (n = 3) length: 25.00 – 29.00 mm, width: 8.50 – 10.00 mm, length / width ratio: 2.90 – 3.03; ♀♀ (n = 7) length: 27.00 – 33.00 mm, width: 9.25 – 11.75 mm, length / width ratio: 2.64 – 2.92. In contrast to nominotypical subspecies elytral pattern more variable, basal 2 / 3 from completely purple or violet, sometimes partly with golden reflections, to mostly fern green with slight purple reflections. Colouration of underside nearly constant. Medial impressions on pronotum shallow to moderately deep, variously punctate, sometimes punctures grouped together and more numerous basally. Elytra in larger specimens appear slightly less sculptured. Four specimens have a more or less indicated posterior lateral impressions on elytra as a group of small dense punctures of olive-green colour, but distinctly impressed only in one specimen.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

04548794694DFFB50F52FB64FBCCF9C2.taxon	discussion	Remarks. NOVAK (2010) described Chrysodema moluensis from series of 24 specimens. Holotype, allotype and 16 paratypes were collected on Molu Island and six additional paratypes from Larat Island. Unfortunately, G. Novak (Vienna, Austria) has passed away and his collection is currently inaccessible. Nevertheless, he provided the description with photographs of both populations allowing us to recognize them with certainty. However, in our opinion the population from the Larat Island is so strikingly different that it deserves its own taxon and is here described as C. (G.) oborili laratensis subsp. nov. See further comments under the latter taxon. The redescription of C. (G.) iris moluensis presented here is based on a topotypic male specimen collected on the same date and obtained from the same batch. NOVAK (2010) did not assign his species to any of the existing subgenera of Chrysodema. In our opinion this taxon represents a subspecies of C. (G.) iris as it has deep basal impression on pronotum (absent in other subgenera of Chrysodema) and has similar but different elytral pattern to C. (G.) iris.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

Length 23.00 mm, width 8.50 mm, length / width ratio: 2.71. Head, pronotum and scutellum bright green with strong golden and copper reflections, impunctate areas of pronotum with violet reflections. Elytra pine green with slight purple reflection (Fig. 51), blue lateroapical margins and suture, and somewhat paler green lateral punctation with golden reflections (Fig. 53). Ventral side bright green with strong copper and golden reflections (Fig. 52). Legs bright green partly with golden and bluish reflections, tarsi yellow, only apical half of last tarsomere and claws metallic green. Pronotum in general coarsely and moderately densely punctate. Medial line well marked, with a few moderately large punctures. Medial impressions very weak, more or less impressed only along medial line, densely punctate, punctures smaller than those lateral to them. Principal impressions deep, round, not connected to basal impressions, and with small dense punctures. Lateral impressions shallow and punctate. Basal impressions moderately deep, subtriangular. Elytra moderately strongly and quite densely punctate, with slightly marked lateral impressions as round groups of coarser and paler coloured punctures (Fig. 53). Rows visible from base to apex, distinctly impressed on apical 2 / 3, more or less regularly arranged, but irregularly double or triple in apical 2 / 3 length. Punctures in rows V – VIII in middle third of elytra quite irregular and dense, and partly grouped, only internally forming more or less distinct rows; spaces 1 – 2 × as broad as diameter of puncture, flat, not reticulate (Fig. 53). Intervals basally flat, not elevated, broad, approximately 3 – 4 × as wide as rows of punctures, impunctate; apically and laterally somewhat elevated and punctate, first interval somewhat vanishing apically. Mid femora in central part strongly shiny, sparsely punctate, punctures large, on sides punctures smaller but coarser and dense. Ventral side of body (Fig. 52) overall coarsely and quite densely punctate, only central parts of thoracic and abdominal ventrites sparsely punctate. Lateral sides of abdominal ventrites densely and coarsely punctate with small punctures, latter on ventrites II to V gradually sparser in apical half and replaced with sparse larger punctures. Lateral side of ventrite V densely punctate only in basal third. Aedeagus (Fig. 70) length 5.95 mm, width 1.22 mm, length / width ratio: 4.88. Apices of parameres obliquely truncate. Penis elongate, subparallel-sided. Variation. Body ♂♂ (n = 49) length: 18.00 – 24.25 (25.75) mm, width: 6.25 – 9.20 mm, length / width ratio: 2.60 – 2.85 (2.96); ♀♀ (n = 42) length: 19.25 – 28.50 (30.75) mm, width: 7.25 – 11.50 mm, length / width ratio: 2.51 – 2.78. Very variable taxon. Impressions on pronotum shallow to moderately deep and of variable size; punctation of pronotum, particularly in smaller specimens, coarser, punctures with larger fovea. Principal impressions round to elongate oval. Colouration of pronotum from mostly vivid green with bluish tint to mostly copper or violet, however majority of specimens with green background colour and golden / copper impressions and foveae of punctures; largely copper to violet pronotum is present only in specimens from Camplong. Colouration of elytra in series from Soë quite uniform, varying only in intensity of purple tint; only six specimens with bluish tint to mostly blue elytra and two with nearly black (? artificially) elytra. In series from Camplong five specimens with blue elytra and green pronotum and seven with pine green elytra and purple pronotum. Lateral impressions on elytra absent to variously present, if present posterior impression deeper and better indicated than anterior, which is only exceptionally truly impressed. Ventral side in most specimens green with variable extent of golden and copper reflections, sometimes nearly whole underside copper; exceptionally dark violet (five specimens with purple pronotum from Camplong). Specimens from Soë were badly damaged and about one quarter of them have missing tarsi. Of the remaining specimens 49 have last tarsomere metallic and 40 uniformly brown.

04548794694BFFB70FD6FF64FD81F9E2.taxon	diagnosis	Differential diagnosis. Chrysodema (G.) katka sp. nov. is most similar to C. (G.) cupriventris as both have similarly green elytra and paler pronotum with golden and copper reflections. They can be easily separated by punctation of abdomen, which is moderately strong and very sparse in C. (G.) cupriventris while dense and coarse in C. (G.) katka. Additionally, C. (G.) cupriventris has lighter tone of elytra (i. e. fern green) and brightly copper-red ventral side. At first glance C. (G.) katka is also similar to C. (G.) foraminifera (also known from Timor) but the latter differ in brightly green ventral side of body and uniformly equally coloured pronotum and elytra while C. (G.) katka has dark ventral side and elytra distinctly darker coloured than pronotum. Chrysodema (G.) foraminifera also differs in narrower and more elongate penis than C. (G.) katka (Figs 56 vs 70).	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

045487946976FF880F05FD64FBB1FBC2.taxon	discussion	Remarks. THÉRY (1935: 248) described Gelaeus iris var. cupripennis, however, in the same work he described also a subspecies Gelaeus walkeri wetteriana therefore the variety cupripennis is infrasubspecific name according to the Article 45.6.4 (ICZN 1999). Nor was it validated before 1985 (Article 45.6.4.1) and hence it is an unavailable name according to ICZN (1999). THÉRY (1935: 248) separated his variety cupripennis based on uniformly copper coloured elytra while C. (G.) iris has iridescent pattern on elytra. He mentioned only ‘ Tenimber’ in catalogue as the distribution of this variety. We were unable to locate any original ‘ type’ specimens for this variety. However, the historical series from Larat (ex collection of J. Moser; MFNB) was loaned to us under the latter name. We presume that the var. cupripennis is the same as C. (G.) oborili laratensis subsp. nov. because most specimens have copper or bronze elytra, which are distinctly darker in C. (G.) oborili oborili and iridescent in C. (G.) iris.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

Chrysodema (G.) sara sp. nov. has the finest punctation of the elytra of all Gelaeus taxa. In generall it is most similar to C. (G.) walkeri walkeri, which has quite smooth elytra in comparison to remaining taxa but still has distinctly impressed rows of punctures and slightly elevated intervals posteriorly while C. (G.) sara does not have impressed rows or elevated intervals. Additionally, C. (G.) sara has the shortest and stoutest penis of all Gelaeus species and is practically the only with a distinctly broadly oval penis.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

The nominotypical subspecies can be easily distinguished from others by usually metallic coloured ultimate tarsomere (brown in other subspecies) and has smoothest elytra with sparsest punctation of all the subspecies. For additional characters see Table 1. Chrysodema (G.) walkeri can be distinguished from other species of Gelaeus by dichromatic dorsal side of body with green pronotum and blue elytra. Similar colour combination is also present in C. (G.) cyanicollis (differing in uniformly metallic green tarsi) and in C. (G.) sara sp. nov.

045487946974FF8C0F6DFB44FEFEFE02.taxon	discussion	Remarks. WATERHOUSE (1892) did not state how many specimens he had at his disposal when describing C. (G.) walkeri. We have located two specimens in BMNH with identical locality label ‘ Damma I. / 92 — 20 ’, however, only one is labelled as type and has the original label handwritten by C. O. Waterhouse. The latter specimen perfectly matches the original description and has identical size to that of mentioned in the original description hence we designate this specimen a lectotype in order to fix identity of this taxon. We do not consider the other specimen as part of the type series as it has larger size than mentioned in the original description and the specimen does not bear any proof that it was studied by Waterhouse when describing C. (G.) walkeri. It is listed among Additional material examined with supplemented data according to the BMNH collection register. The number ‘ [18] 92 — 20 ’ refers to the following entry in the register: ‘ 458 coleoptera, various localities presented by the Lords of the Admiralty: collected by Mr J. J. Walker during the cruise of HMS ‘ Penguin’; [Nos.] 5762 – 5988 (266 coleoptera) Damma Island Nov [ember] 6 – 11 [18] 91 ’ (M. Barclay, pers. comm.).

(G.) walkeri this one is easily distinguished by small and very dense punctation of elytra, particularly in apical third, where punctures are almost touching each other, while other subspecies have distinct intervals. The subspecies C. (G.) walkeri kubani subsp. nov. also has dense punctation of elytra but still has distinct intervals in apical third and is much more sculptured. Chrysodema (G.) walkeri horaki subsp. nov. has also completely irregular punctation in rows V – VIII without distinct intervals (more or less distinct in other subspecies).

04548794697EFF830F0AFB24FDBFFAC8.taxon	discussion	Remarks. THÉRY (1935: 248) described Gelaeus walkeri var. nigriventris, however, in the same work he described also a subspecies Gelaeus walkeri wetteriana therefore the variety nigriventris is infrasubspecific name according to the Article 45.6.4 (ICZN 1999). Nor it was validated before 1985 (Article 45.6.4.1) and hence it is an unavailable name according to ICZN (1999). We have located one female specimen in NHMB from the locality Moa mentioned by THÉRY (1935) and provided with his original paratype label as the variety nigriventris. Additionally we have found a series of specimens in MFNB with identical locality label (specimens originated in the collection of Julius Moser) agreeing also morphologically with the NHMB specimen. In our opinion this taxon is a distinct subspecies of C. (G.) walkeri and we decided to use the same name as Théry. LANDER (2003) provided a colour photograph of C. (G.) walkeri, however, the specimen does not have the last tarsomere metallic green thus it does not belong to the nominotypical subspecies. In our opinion the depicted specimen belongs to C. (G.) walkeri nigriventris subsp. nov. based on general shape.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

(G.) walkeri this one is easily distinguished by elytra with distinct large lateral impressions and green lateral sides and suture, while the other subspecies do not have differently coloured margins of elytra or suture and the lateral impressions are rarely present and if so they are very small and shallow (basically present only as a group of several punctures).

04548794697CFF850F36FAFAFBE0FE02.taxon	discussion	Remarks. The paratype of C. (G.) walkeri rejzeki subsp. nov. deposited in BMNH is labelled as syntype of C. (G.) cupriventris. The latter species was described from ‘ Macassar’ and KERREMANS (1898) must have had at least two specimens as he gave length span ‘ Long., 21 - 28; larg., 7 - 9 mill. ’. However, this ‘ syntype’ has locality Alor and measures 30.75 × 11.25 mm and is very different from the other syntype of C. (G.) cupriventris deposited in BMNH. Therefore we do not consider it as a part of the type series of the latter species. We assume that Kerremans acquired this specimen after the description of C. (G.) cupriventris and erroneously labelled it as its type. Most likely it represents a voucher specimen for the record from Alor mentioned by him (KERREMANS 1903). See additional remarks under C. (G.) cupriventris.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

04548794697AFF840F61FE44FEBBF9C2.taxon	description	Redescription of lectotype. Well preserved ♂ specimen with all appendages intact, elytra with transverse crack at base. Length 27.00 mm, width 10.00 mm, length / width ratio: 2.70. Body generally black (Figs 54 – 56) partly with dark metallic reflections: purple on principal impressions of pronotum, marginal punctures on elytra, and most of ventral side; basal impressions of pronotum, and legs and mouthparts at joints with greenish tint. Apical half of last tarsomere and claws darkened but not metallic. Pronotum in general coarsely and densely punctate particularly anteriorly and laterally, punctures foveolate. Medial line well marked and impunctate. Medial impressions distinct, moderately deep, densely punctate, towards centre somewhat sparser; punctures slightly smaller than those along anterior margin. Principal impressions shallow and weakly bordered from disc, densely punctate. Lateral impressions shallow and punctate. Basal impressions small with anterior part less impressed than basal part. Elytra without lateral impressions, with strongly elevated intervals and distinctly impressed rows of punctures from base to apex. Punctation of elytra overall very coarse and dense. Rows visible from base to apex, irregularly double (internal) or triple (external) from basal third of elytra to apex. Punctures in rows V – VIII in middle third of elytra forming groups of 2 – 4 separated by elevated impunctate folds forming irregular elevated reticulate sculpture (Fig. 56). Intervals approximately 4 × as wide as rows of punctures, with shallow transverse wrinkles, and apically with several additional punctures. Mid femora in central part moderately densely punctate, punctures large, on sides punctures smaller and denser. Ventral side of body (Fig. 55) overall coarsely and quite densely punctate. Abdominal ventrite I laterally densely and coarsely punctate, punctures large. Ventrite II laterobasally densely punctate, punctures distinctly smaller than on ventrite I, lateroapical area sparsely punctate. In each of subsequent ventrites densely punctate area proportionally smaller to the sparsely punctate area. Aedeagus (Fig. 71) not fully sclerotised and broken between parameres, therefore its width was not measured, length: 7.29 mm. Apices of parameres rounded. Penis elongate, subparallel-sided. Variation. Body ♂♂ (n = 2) length: 27.00 – 27.25 mm, width: 10.00 mm, length / width ratio of body: 2.70 – 2.73; ♀♀ (n = 2): length: 29.50 – 30.50 mm, width: 11.00 – 12.50 mm, length / width ratio of body: 2.44 – 2.68. One female has pronotum slightly smaller and with sparser punctation, mainly in central part. Subhumeral denticle in paralectotypes distinctly larger, particularly in males.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

04548794697AFF840F61FE44FEBBF9C2.taxon	diagnosis	Differential diagnosis. Chrysodema (G.) wetteriana is readily distinguished from other taxa of the subgenus by nearly black body with slight metallic reflections on pronotum and strongly elevated intervals on elytra. It is the most sulcate species of all Gelaeus.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).

04548794697AFF840F61FE44FEBBF9C2.taxon	discussion	Remarks. THÉRY (1935) described this taxon as subspecies of C. (G.) walkeri based on the material from RMNH but did not mention the number of specimens he had at disposal. At the beginning of the description he stated: ‘ Taille du type (long 28 mm; 5.25 mm). ’ but did not mentioned the sex of the ‘ type’ nor is it indirectly indicated in the description. The width of ‘ type’ must have been given erroneously as the width of studied specimens is 10 – 11 mm; the length is also not in agreement with presently studied specimens as they are either smaller or larger. The description itself is rather short followed by longer paragraph comparing C. (G.) wetteriana to C. (G.) walkeri where Théry mentioned a female of C. (G.) wetteriana. In the last sentence he compared the apical notch on abdominal ventrite V in both sexes making obvious he must have had more than one specimen. There are two specimens (male and female) of C. (G.) wetteriana in RMNH, however, both were labelled by Théry as ‘ type’. Additionally, there are two specimens labelled as ‘ paratype’ deposited in BMNH and MNHN respectively. All four beetles bear identical locality label and Théryʼs original identification labels. As two of the four specimens are labelled ‘ holotype’ and the description is very short it is not possible to identify any of the specimens as the type and we consider all four to be syntypes. According to the reference number 1934 – 692 the BMNH specimen was presented to the museum by Théry himself. In order to conserve the concept of this taxon and associate it with the morphology of male genitalia we designate the male specimen deposited at RMNH as the lectotype. The MNHN syntype has two locality lables, one identical to other syntypes, however, on the other is printed Ceram, Jilo. We assume the second locality label was accidentally pinned under the specimen as it was remounted. As mentioned above Théry described this taxon as subspecies of C. (G.) walkeri. In general C. (G.) wetteriana is most similar to the latter species-group, particularly to C. (G.) walkeri kubani subsp. nov. but it is very distinct (see differential diagnosis). Therefore we rise its rank to species.	en	Frank, David, Sekerka, Lukáš (2016): Revision of the subgenusGelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae).
