5E0BA016863DFF9BFE9FFD52FA83FB83.taxon	diagnosis	DIAGNOSIS. Body variegated (Figs 71 – 111), nearly glabrous dorsally, with very short individual setae scattered over elytral disc, without or with similar setae at pronotal base and / or at apex, and near supra-ocular seta. Head mostly pale, with a contrastingly darker V- or U-, or Y-shaped, patch between eyes; this patch mostly extended onto neck and often reaching pronotum. Pronotum impunctate or with very few large punctures; when present, dark median stripe not or barely wider in apical than in basal half. Prosternum and propleura glabrous except 2 – 6 strong paramedian setae between procoxae. Elytra subparallel-sided, with humeri distinct to trapezoidal, in the latter case much broader apically than basally due to humeri imperceptible; ridges wide and slightly convex. Elytral pale pattern generally consisting of large to missing humeral spot, transverse median band, rather narrow lateral margin, and apical margin. Transverse median band more or less strongly dentate at even ridges anteriorly and at odd ridges posteriorly, inwardly reaching ridge 2; apical margin mostly narrow or missing, in the latter case only including apices of elytral ridges. Body mostly macropterous, sometimes (S. stenoderus and S. marginicollis) apterous. In some populations of S. javanus, brachypterous adults have also been observed. Profemora laterally tumid in male. Abdominal apical urites (Figs 1 – 20): In female, tergite VII with 9 – 17 rather strong setae; tergite VIII with median sclerotization (psm) transvere subrectangular, apical depigmented region (adr) long, densely tuberculate and setulose; sternite VIII densely pubescent, without medioapical sclerite, with a membranous area just in front of 14 – 20 strong apical setae and inner internal carina running close to re-entrant angle between base and laterobasal apophysis. Sternite VII bisetose to quadrisetose in male. Median lobe of aedeagus with apex round in crosssection to flattened dorsoventrally, mostly finely carinate ventro-apically. Urite IX evenly membranous ventrally (Figs 56 – 64) in female; gonocoxite moderately long, glabrous at dorsal edges. Spermathecal receptacle from Y-shaped, with horns unequal in length, to bulbous, with one horn tumid and the other totally absorbed (Figs 56 – 70).	en	Fedorenko, D. N.

5E0BA016863DFF9BFE9FFD52FA83FB83.taxon	biology_ecology	HABITATS AND HABITS. The adults are nocturnal carnivores generally found in open habitats in lowlands and piedmonts. Many species are frequent on bogs and by pools in floodlands or along rivers and larger streams, including in plant debris on riverbanks. Some of them occur also along forest edges, wood trails and even roads. Macropterous species often flight to light at night. Sympatric species of the group often live syntopically.	en	Fedorenko, D.

5E0BA016863DFF9BFE9FFD52FA83FB83.taxon	discussion	COMMENTS. This group includes ten species in the Oriental region north to the East Asian Palearctic subregion, with some others occurring in the Afrotropical and Madagascan regions; S. hispanicus (Dejean, 1824) from southwestern Paleactic is most likely to belong to the group, too. Most of these species are very similar in appearance, including body shape, proportions and colour pattern. Because the pattern varies greatly between individuals as well as between local populations of a species, particular color morphs being often observed in different species. As a result, the species of the group are hard to determine, and examination of the male genitalia is very advisable for the purpose. The group is here divided into the javanus - subgroup and the fimbriatus- subgroup, based chiefly on a particular groundplan of the internal sac of aedeagus.	en	Fedorenko, D. N.

5E0BA016863FFF9DFC50FB9BFE99FD2E.taxon	distribution	GEOGRAPHIC DISTRIBUTION. This species has long been considered to occur throughout the Oriental region east to, and including, the Papuan region, ranging as far north as eastern China and the Maritime Province. Andrewes [1926] reported S. javanus from Luzon, the Philippines, and Lowerens [1953] from the Lesser Sunda Isles (Sumba, Flores, and Timor). On the other hand, Darlington [1968] deleted S. javanus from the Papuan faunal list and Giachino [2005] neither reviewed nor keyed this species for New Guinea, too. Habu [1967, 1984] only reported S. javanus from the Ryukyus and the Satsunan Islands in southernmost Japan (Takara, Amamioshima, and Tokunoshima Is.), and the records of the species in China and the Maritime Province [Lafer, Zolotarenko, 1971; Lafer, 1973] proved to refer to S. agnatus (see below). Andrewes [1929] noted also that he had seen no Indian specimens of S. javanus other than one or two from Odisha and Assam. This, combined with no recent records made in India [Venugopal, Thomas, 2019], suggests that S. javanus is either rare eastern species in India or absent from there at all. From this one could deduce that the species range extends in Indochina south to the Sunda Isles and east to south China, including Taiwan, easternmost Japan, and probably also the Philippines.	en	Fedorenko, D.

5E0BA0168639FF9FFCB8FEBAFD9EF8D4.taxon	discussion	COMMENTS. According to the descriptions, S. lissoderus is distinctive from S. picicollis in only having the head and pronotum entirely pale (vs. infuscated). My comparison of the holotype of S. lissoderus and a syntype of S. picicollis from Siam, as depicted in Venugopal and Thomas [2019: Figs 2 A and 2 C, respectively] with both each other and the specimens listed above has revealed no differences except in body colour. Because diferently coloured males from one and the same population as well as from different populations have similar aedeagi, the two names are here considered as conspecific and only referred to as different colour morphs, either pale (forma ‘ lissodera’) or melanistic (forma ‘ picicollis’).	en	Fedorenko, D.

5E0BA0168635FF92FCE4FEBAFC6EFCCE.taxon	biology_ecology	HABITATS AND HABITS. This species has forestdwelling habits, being generally confined to 200 – 600 m altitudes in piedmonts, with three local populations found at 1050 – 1400 m in Central Vietnam. This species often live syntopically with some other species of the group, such as S. consularis (in the Pu Mat Nature Reserve and the Ke Bang National Park in Vietnam, and also in the environs of Pai, Thailand) or S. agnatus (in the Song Thanh National Park).	en	Fedorenko, D. N. (2021): Stenaptinus (Coleoptera: Carabidae: Brachininae) of Vietnam. Note 2.

5E0BA0168635FF92FCE4FEBAFC6EFCCE.taxon	discussion	COMMENTS. This species is incapable of flight because of constantly apterous condition of the adults. Since flight function lost the elytra has become much more variable in shape than in macropterous species, resulting in wider ranges of the ratios EL / EW and EW / PW (Table). Another result is that local populations of S. stenoderus tend to be more isolated from one another than in species having full or polymorhic wings and interpopulation variability tends to surpass intrapopulation variability accordingly. Specifically, the elytra seems to be more dilated apically in populations from Indochina than in those from India. In Thailand and northern Vietnam, the adults have the elytra short, with median fascia not seldom narrow and strongly dentate. Black colour on the head and pronotum becomes considerably reduced in size in populations from Nghe An Province. The adults from there have the Y-shaped patch on vertex shortened from behind and transformed into a pentagon, which is somewhat stellate due to the angles slightly projecting, and pronotum pale, except for its base, apex and narrow lateral margins. The recently described S. lei is distinctive in only having a generally larger body, the pronotum with sides more sinuate in front of base and thence with basal angles rather acute, and the elytral median facia wide and not or only slightly dentate. All these characters have been observed in some other populations of S. stenoderus, therefore S. lei is here considered as a group of southern populations of S. stenoderus in Vietnam. Stenaptinus stenoderus and S. lissoderus may be more closely related to each other than to S. stenoderus because aedeagi of the former two are more similar in having preapical frontal bulb of the internal sac (vs. having no this bulb in S. consularis).	en	Fedorenko, D.

A smaller body, 13 mm in length, in couple with the entirely pale forebody, only differentiates the next Chinese species, S. chinensis, from S. agnatus. Because the two characters are observed in S. agnatus as well, the synonymy S. chinensis = S. agnatus is not improbable, too. The name ‘ Thieme’ (‘ China: Thieme’) from the description of S. chinensis seems to be patronymic Dutch, that of probable collector of the species, and the fact that a certain steersman Thieme has been mentioned by Kuiper [2016] relative to the island of Amoy in the 19 th century is what may argue for the surmise. If true, the holotype of S. chinensis originated either from the environs of Xiamen or another treaty port in China, e. g., Shanghai, Ningbo, Fuzhou, or Guangzhou. Lafer [Lafer, Zolotarenko, 1971; Lafer, 1973] reported ‘ S. javanus ’ from the southernmost Maritime Province based on several male and female specimens, redescribed the species at his hand in details and then [Lafer, 1989] illustrated it by the line drawing of S. javanus from Habu [1967: Pl. 27, Fig. 3; 1984: Fig. 179]. My comparison of the digital images of four specimens of S. javanus: Lafer, 1971 reveals that all of them belong to S. agnatus only. This suggests that most if not all records of S. javanus in mainland East Asia should be referred to as S. agnatus.	en	Fedorenko, D. N.

The species was described based on three syntypes from either southeastern India or Thailand, or Java; that from India is here designated as the lectotype. Unlike the other species of the group, S. fimbriatus is sexually dimorhic in body proportions. In particular, the elytra are slightly longer and narrower in males than in females: EL / EW 1.52 – 1.65 (1.58) vs. 1.46 – 1.58 (1.50) and EW / PW 1.65 – 1.86 (1.78) vs. 1.78 – 1.97 (1.90), respecively (4 ♂♂ and 4 ♀♀ from the Cat Tien NP, 2 ♂♂ from Sumatra, and 2 ♀♀ from Cambodia measured). Besides, I provisionally determine three male specimens [Natural History Museum, 2014] from the Malay Peninsula as S. fimbriatus, with reservation that at least some of them may belong to S. sumatrensis sp. n.

5E0BA0168633FF89FF04FE01FE1EFBD2.taxon	discussion	COMMENTS. The female lectotype is distinctive from the other examined specimens of this species in only having the elytral pale pattern overdeveloped, with black colour reduced to a narrow zigzag between large humeral spot and wide median band. This band is subequally dentate, anteriorly at the ridges 4, 6 and 8, posteriorly at the ridges 3, 5, 7 and at the lateral edge. It touches the sutural ridge and reaches lateral margin, being extended along lateral edge to humeral spot and along interval 8 in its outer half to rather a widely pale apex, thus leaving extreme lateral margin black medially and at the apex of the humeral spot. This species was redescribed by comparing it with S. suensoni in many points [Schauberger, 1923]. Schauberger also described the aedeagus of S. marginicollis for the first time and reported the species from Shanghai, Hangchow (= Handzhou, Zhejiang) and Mukden (= Shenyang, Liaoning), China.
