Paratypes : Russia : North Caucasus : Krasnodar Terr., Sochi , Lazarevskoe , 26.V 1976 , 1♀ ( V.I. Tobias ); same locality and collector , 19.VI 1976 , 1♀ ; same locality and collector , 23.VI 1976 , 1 ♂ [ PRC ] . DIAGNOSIS. Chrysis mokrousovi Rosa , sp. n. belongs to the succincta speciesgroup and is morphologically similar to C. illigeri Wesmael, 1839 . The female can be easily separated through body coloration: lower face (in frontal view), genae and oral fossa to occiput (in ventral view), mesosoma and legs metallic red ( Fig. 7C ); mesopleuron with greenish or bluish reflections ( Fig. 5B ); T3 apical margin bluish to black ( Fig. 5D, 5E ) ( C. illigeri has a typical coloration pattern of C. succincta , with head and mesosoma blue and anterior margin of pronotum and mesoscutum metallic red). The male has green head, green to blue propodeum and T3 entirely metallic red, including the posterior margin; anyway, the red coloration of mesosoma is distinctly characterized when compared with the coloration of C. illigeri male (coloration pattern of C. succincta ). Besides the coloration, the male can be separated by the different shape of genitalia, with straight internal margin of gonocoxae (Figs 6F, 6G). DESCRIPTION. Body length 5.5–7.0 mm. Fore wing length 3.5–4.0 mm. Female . OOL = 1.9 MOD; POL = 1.8 MOD; MS = 1.6 MOD; relative length of P: F1: F2: F3 = 1.0: 1.5: 0.7: 0.7. Head . Vertex and frons with relatively small and contiguous punctures; TFC barely raised, medially straight, and slightly downcurved at both ends (in the holotype slightly raised only medially ( Fig. 5A )); scapal basin widely polished in the upper third; medially polished (about 2 MOD width); laterally punctate, in the lower two thirds, with minutes punctures; subantennal space about 1.0 MOD; anterior margin of clypeus medially slightly emarginated, laterally with thickened brownish rim; in frontal view, malar spaces convergent. Genal carina fully developed to mandible. Mesosoma . Pronotal groove deep and narrow, almost reaching 2/3 of pronotum length ( Fig. 7C ); in dorsal view, punctuation all over mesosoma similar, with coarse and contiguous punctures of different size ( Fig. 7C ); anterior margin of mesoscutellum medially impunctate and darker to purplish; propodeal teeth slightly divergent ( Fig. 7C ). Mesopleuron with episternal sulcus formed by deep, large foveate punctures ( Fig. 5B ). Fig. 5. Chrysis mokrousovi sp. n. , holotype, ♀: A – head, frontal view; B – mesosoma, lateral view; C – metasoma, dorsal view; D – metasoma, postero-lateral view; E – metasoma, posterior view; F – metasoma, ventral view. Scale bar = 1.0 mm. Fig. 6. A–F – Chrysis mokrousovi sp. n. , paratype, ♂, Sochi. G – C. illigeri . A – head, frontal view; B – mesosoma, dorsal view; C – metasoma, dorsal view; D – metasoma, postero-lateral view; E – metasoma, ventral view; F, G – genital capsule. Scale bar for A–E = 1.0 mm, F, G = 0.5 mm . Metasoma . Punctuation on T1 dense with contiguous punctures of different size; on T2 with geminate punctures of the same size, more spaced (1 PD apart) with polished intervals ( Fig. 5C ); on T3 with irregular, contiguous and corrugated punctures; pit row with deep and elongate pits ( Fig. 5D ); T3 apical margin with four short apical teeth ( Fig. 5E ); medial teeth on posterior margin of T3 extending further posteriorly than lateral teeth, and located in close proximity. Coloration . Body entirely metallic red flame, excluding blue frons, vertex and partly genae; bluish to green sulci and alar foveae on mesopleuron; purplish to black apical margin of T3, after pit row. In some paratypes propleuron, lower mesopleuron and metapleuron bluish. Black spots on S2 covering 2/3 of the sternite length, not strongly oblique posteriorly (similarly to C. illigeri ). Tegulae brown, without metallic reflections; tarsi dark brown; scape, pedicel and F1 metallic red, rest of flagellum black. Hind wings smoky. Vestiture . Body with whitish, short, erect setae (1.0–1.5 MOD) laterally and ventrally longer (up to 2.0 MOD). Legs with erect whitish setae, shorter on foretibiae (1.0 MOD), longer on mid- and hindtibiae (up to 2 MOD). Male . Similar to female, but scapal basin laterally extensively punctate, with short, silvery appressed setae; head metallic green; T3 entirely metallic flame red, including apical margin; T3 apical teeth short and blunted as in C. illigeri ( Fig. 6D ); tegulae basally metallic; S2 black spots small and subrectangular ( Fig. 6E ), medially broadly separated, as long as half of sternite length. Genital capsule similar to C. illigeri but with straight internal margin of gonocoxae. DISTRIBUTION. Russia ( Krasnodar Territory), Abkhazia Republic. ETYMOLOGY. The specific epithet mokrousovi (masculine name in genitive case) is named after Mikhail Mokrousov ( Nishny Novgorod , Russia ), who collected and donated the holotype to ZIN .
