3927340C07014210FCE5FA75255851E5.taxon	materials_examined	Brullé (1846) provided the descriptions of three species in the genus Pyria Lepeletier & Serville, 1825: P. oculata Fabricius, 1775 (from Eastern India), P. smaragdula Lepeletier & Serville, 1825, nec Fabricius, 1775 [currently C. stilboides Spinola, 1838] (from Africa) and P. canaliculata Brullé, 1846 (from Africa). In Kimsey & Bohart’s monograph (1991), the holotype of P. canaliculata was reported as being deposited at MRSN. However, as observed by Rosa & Xu (2015) and Rosa (2024), no specimens from Brullé’s collection were found in the Spinola collection, currently housed at MRSN. In fact, the species was described on two syntypes originating respectively from the collections of Serville and from the MNHN (“ Hab. le Sénégal. C. M. [= Collection du Muséum] et Collect. de M. Serville ”). The syntype of P. canaliculata from the Paris Muséum (Fig. 1) is still preserved in the collection of MNHN, while the whereabouts of the second syntype remain unknown. Actually, the examined syntype of P. canaliculata at MNHN turned out to be a specimen of C. stilboides.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.

3927340C07014210FCE5FA75255851E5.taxon	description	Regarding P. canaliculata, the description provided by Brullé (1846) closely resembles that of C. stilboides, with the only distinction being the shape of the metanotal mucron, indicated as non-canaliculate (haud canaliculato). In fact, Brullé did not mention other important diagnostic characters, such as wing venation (including an additional vein extending from the radial sector in C. simillima sensu auctorum), or the shape of the head, with a simple transversal frontal carina in C. simillima (strong, with three branches in C. stilboides), or even differences in the length ratio of first and second flagellomeres, which vary among Pyria species; for instance, in C. stilboides female (Fig. 2 B) F 1 l / w = 1.0; F 2 = 2.0 × F 1 length; in C. simillima female (Fig. 2 C) F 1 l / w = 1.6; F 2 = 1.3 × F 1 length; in C. smithii female (Fig. 2 E) F 1 l / w = 2.5; F 2 = 1.1 × F 1 length. Also, although Brullé detailed the coloration of the antennal segments (identical in both descriptions of stilboides and canaliculata, with the scape and part of pedicel green, and with metallic green colour extending until the second flagellomere in smithii or simillima sensu auctorum), he did not observe these morphological and color differences.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A. (2025): New findings of cuckoo wasps for Yemen with nomenclatural changes and review of the Arabian hexadentate species of the genus Chrysis Linnaeus, 1761 (Hymenoptera, Chrysididae). Zoosystema 47 (11): 151-166, DOI: 10.5252/zoosystema2025v47a11, URL: https://sciencepress.mnhn.fr/sites/default/files/articles/pdf/zoosystema2025v47a11.pdf
3927340C07014210FCE5FA75255851E5.taxon	diagnosis	In the diagnosis of the genus Pyria, Brullé (1846) stated that the genus is distinguished from Chrysis by having a short pedicel and first flagellomere of equal length, with the second flagellomere being significantly longer than the first and longer than the pedicel and first flagellomere taken together (“ On distinguera ensuite les Pyria des Chrysis par les deuxième et troisième articles des antennes égaux en longueur et par le quatrième, beaucoup plus long que le troisième et le plus long de tous, si l’on en excepte le premier ”). This definition excludes C. simillima sensu auctorum from the synonymy with C. canaliculata for its elongate first flagellomere. Due to indefiniteness regarding the description of Brullé of a non-canaliculate mucron, a character shared with other African species, we designate the syntype of C. canaliculata at MNHN as the lectotype (Fig. 1), and considering Brullé’s diagnosis of Pyria, and the syntype housed at MNHN, we synonymize C. canaliculata Brullé, 1846 with C. stilboides Spinola, 1838. The lectotype bears the following labels: Sénégal / 46 / Chrysis canaliculata [handwritten by Brullé] / Museum Paris Sénégal / R. du Buysson det. 1897. Du Buysson (1898) had already synonymised C. canaliculata (as canalicuta) with C. orientalis Guérin-Méneville, 1842, an Oriental species closely related to C. stilboides. The new synonymy does not significantly impact the current classification of the group, because C. canaliculata was listed only by Mocsáry (1889), who reported the original description, and consequently by Kimsey & Bohart (1991) and Madl & Rosa (2012) in their catalogues. Conversely, the name C. simillima was used in European collection (first author pers. note), and in Linsenmaier’s publications and keys (Linsenmaier 1994, 1999). However, Linsenmaier’s identification corresponds to specimens identified as C. simillima by du Buysson (1898) and deposited at MNHN, but not syntype specimens (see below), and not to the real type of C. simillima found at the NHMUK.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.

3927340C07034211FCE5F8F422B15324.taxon	materials_examined	According to Kimsey & Bohart (1991), the holotype of C. simillima was deposited at MSNG. However, we found out that this type had never been deposited either in Gribodo’s or Invrea’s collections (Rosa 2009). Instead, the holotype was found in the collection of the NHMUK (box 79), along with a syntype of C. smithii (box 76). In fact, both types were sent back to Smith by Gribodo who only retained a syntype of C. smithii for his collection (Fig. 3). Chrysis simillima (Figs 2 C; 4 C) is similar to C. stilboides, albeit with a simple, sharp transverse frontal carina lacking three branches, a longer ratio of length of the first flagellomere (l / w = 1.6 vs 1.0), a shorter second flagellomere (1.3 × F 1 length vs 2.3) and a larger, triangular and flat metasomal mucron (smaller and medially concave in C. stilboides). This species has not yet been found in the Arabian Peninsula and previous records reported by Linsenmaier (1994) refer to C. smithii Gribodo.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.

3927340C07034210FF4CF9F5234A52E4.taxon	materials_examined	The holotype of C. smithii (Fig. 3), listed by Kimsey & Bohart (1991) at MSNG, was examined by Rosa (2009). However, a second syntype was subsequently found at NHMUK (B. M. Type Hym. 13.151) (box 76). Based on the assumption given in Kimsey & Bohart (1991), we consider the specimen housed at MSNG as the lectotype by inference of the term holotype (ICZN 1999). Furthermore, Kimsey & Bohart (1991) synonymised C. smithii and P. simillima, despite being both described by Gribodo (1879) on the same page and in different genera. Considering that Gribodo was an expert chrysidid taxonomist, it is at least unlikely that he described the same species in two different genera. In fact, the types of these two species are distinct. The type of P. simillima has short first flagellomere and resemble C. stilboides, whereas C. smithii has an elongate first flagellomere and was not included in the genus Pyria. Chrysis smithii (see the description below) is therefore clearly distinct from C. simillima and C. stilboides, and it is here resurrected to species rank.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.

3927340C07034210FF4CF9F5234A52E4.taxon	diagnosis	Based on the study of material identified at MNHN and NMLU, we can state that C. smithii is the correct name for the species misidentified by du Buysson (1898) and Linsenmaier (1994, 1999) as C. simillima. According to Linsenmaier (1994), this species belongs to the lyncea group due to the shape of the head, pronotum and mesopleuron which align with the diagnostic criteria of the lyncea group. However, other diagnostic features, such as the metasomal apical margin and the shape of black spots on second sternum, do not match the diagnosis of the lyncea group (see below).	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.

3927340C070D421EFCE5FA35227753E3.taxon	discussion	Linsenmaier (1994: 199, 1999: 250) synonymised C. caroli, described from Tunisia with C. jousseaumei because the two species share the dentate lower mesopleuron. However, the body sculpture and colour pattern of C. caroli are clearly different. In C. caroli the first tergum is densely micropunctate on interspaces among large punctures (Fig. 7 F) (vs large, even punctures with polish interspaces in C. jousseaumei, Fig. 7 E); the second tergum has even, mediumsized punctures and densely micropunctate interspaces (vs large punctures with polished interspaces in C. jousseaumei); the body color pattern in C. caroli is green with blue areas on mesosoma, and blue basal and lateral bands on metasomal segments, while it is entirely dark blue to purplish in C. jousseaumei. For these notable differences in diagnostic characters, we consider C. caroli du Buysson, 1907 as a valid species.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.

Chrysis jousseaumei is characterised by toothed mesopleuron (Fig. 7 C), violet to purplish body colour, large punctures with polished interspaces covering the whole body (Fig. 7 E). Chrysis rubroviolacea, as correctly given in the original description, has a simple, unmodified mesopleuron, without any evident tooth (Fig. 7 D); in addition, the shape of the head is different (Fig. 7 B), being clearly transverse (l / w = 0.7) (measure taken from the transverse frontal carina to clypeal margin) and the shortest distance between inner eye margin instead of triangular, and short (l / w = 0.8) as in C. rubroviolacea (Fig. 7 A); the episternal sulcus is formed by larger foveae (Fig. 7 D); the black spots on second sternum are narrower, almost half as wide as long. For these notable differences in diagnostic characters, we consider C. rubroviolacea Mocsáry, 1913 as a valid species.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.

The real placement of these two species is somewhat uncertain, and they may represent at least a separated subgroup with the shape of the head, pronotum and mesopleuron corresponding to the diagnosis of the lyncea group. Moreover, they share common characters with the smaragdula group: elongate first flagellomere (l / w = 2.5) in the female, the shape of the apical margin with six aligned teeth and the large black spots on the second metasomal sternum. A unique character of these two species is found in the forewing, with the ancillary vein extending from the Radial sector (Fig. 9 D). This vein is barely visible in the species closely allied to C. lyncea.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.

This group is anyway heterogeneous in the definition given by Kimsey & Bohart (1991). Linsenmaier (1959, 1994, 1999) split it in several groups, e. g. diehli group, fasciata group, sexdentata group, and the decemdentata group, which was recently confirmed as a distinct group by Rosa & Halada (2021). According to Linsenmaier’s (1994) classification, the Arabian species should be included as follows: C. jousseaumei in the sexdentata group, with the ancillary vein originating from the Radial sector; C. diehli in the diehli group, which is characterized by specimens with sexdendata habitus and first flagellomere shorter than the second in both male and female.	en	Neveen, Paolo Rosa, Gadallah, Neveen S., Edmardash, Yusuf A.
