Chrysis niehuisi sp. n. belongs to the C. ignita species group, C. ruddii subgroup, for: short pronotum, its length less than one fourth of its width; F1 largely non-metallic; scapal basin with dense, appressed, white pubescence. Chrysis niehuisi sp. n. is related to C. rutiliventris Abeille de Perrin, 1879, from which it is separated by TFC undulate, M-shaped ( vs. arched in C. rutiliventris ); T3 with elongate, slender apical teeth ( vs. short and basally broadened); elongate propodeal teeth ( vs. shorter); body colouration green, with golden-rosy T2 and T3 ( vs. blue head and mesosoma, and uniformly red metasoma). C. niehuisi sp. n. is separated from the Pakistani C. proba Linsenmaier, 1959, stat. n. ( Figs 41–43 ) by complete TFC ( vs. medially interrupted in C. proba ( Fig. 42 )); metasomal punctation denser and smaller ( vs. larger and scattered); apical teeth of T3 less elongate than in C. proba ; T1 concolorous with mesosoma, and strongly contrasting with the remaining metasomal segments ( vs. metasoma overall red to violet). The above-mentioned features also lead me to raise C. proba to specific rank. Other Asian species related to C. niehuisi sp. n. are C. carnifex Mocsáry , 1889 (from China : Shanxi ), C . crebropilosa Tarbinsky, 2001 and C. chlorochrysea Tarbinsky, 2001 (both from Kyrgyzstan ). C. carnifex is recognizable by sparse body punctation, in particular by habitus, lateral view; 37 – head, frontal view; 38 – metasoma, postero-lateral view. Scale bar Figs 35–38. Chrysis niehuisi Rosa , sp. n. , holotype ♂: 35 – habitus, dorsal view; 36 – = 1.0 mm. the even and sparse punctation on T2, shortened F1, and sharp, spiniform teeth of the last tergum; C. crebropilosa is recognizable by extremely elongate whitish setae all over the body; C. chlorochrysea ( Figs 39–40 ), whose females are variable in colouration and may have green T1, is separated by shape of apical teeth of T3 (spiniform in males and basally larger in females, with wider intervals), punctation of T2 larger and sparser, and male genital capsule ( Fig. 56 ). Figs 39–43. 39, 40 – Chrysis chlorochrysea Tarbinsky: 39 – holotype ♀, habitus, dorsal view; 40 – ♂ , habitus, dorsal view; 41–43 – C. proba Linsenmaier, holotype ♂ : 41 – habitus, dorsal view; 42 – head, dorsal view; 43 – metasoma, postero-lateral view. Scale bar = 1.0 mm. DESCRIPTION. Body length 8.0 mm. Fore wing length 5.8 mm . Male . OOL = 2.1 MOD; POL = 1.2 MOD; MS = 1.0 MOD; relative length of P:F1:F2:F3 = 1.0:1.5:1.4:1.3. Head . In full face view, length 1.6 mm , width 2.2 mm . Apex of clypeus slightly arched; TFC strong, vaguely M-like, its distal margin ending close to eye margin; scapal basin with very dense and fine punctation, covered with dense, appressed, silvery setae; punctures on vertex and occiput small, reticulate. Malar space short 0.7 MOD, as long as one third of F1. Subantennal distance about 1.0 MOD. Subgenal carina complete, extending to mandible joint. Mandible without subapical tooth; in lateral view, mandible relatively thick, its sides gradually converging towards apex and basally only slightly concave. Mesosoma . Length 2.8 mm ; width (PPW) 1.9 mm . Pronotum anteromedially slightly depressed, without distinct anteromedian groove; punctation double, uneven, with larger punctures subcontiguous to subconfluent. Mesoscutum with dense, small to medium-sized punctures, with very narrow polished interstices; lateral area of mesoscutum with scattered punctures and tiny dots on polished interstices; notauli and parapsidal lines complete; notauli with deep, elongate pits, decreasing from posterior to anterior end. Mesoscutellum with punctation similar to mesoscutum, with slightly larger punctures. Metanotum with larger, subreticulate punctures of different size; on anterior margin with a row of elongate foveae. Mesopleuron with episternal sulcus formed by deep and large foveae. Propodeal teeth hardly divergent, pointing backwards. Metasoma . Length 3.5 mm . T1 with medium-sized, scattered punctures, about 1–2 PD apart, denser on margins, with interstices covered by tiny punctures. T2 with double puncture, very dense anteromedially, scattered posteriorly and laterally, with larger polished interstices. T3 with small, even, very dense punctures, without polished interstices; pits of the pit row large (0.7 MOD), round and deep; apical teeth triangular, pointed, subequal in length, and with similar indenture. Median longitudinal carina present on T2 and T3. Black spots on S2 small, trapezoidal, connected to lateral margins, with oblique inner margins, medially largely separated (about 1 MOD), similar in shape to C. impressa Schenck, 1856. Coloration. Head, mesosoma and T1 green; T2 and T3 red-rosy; metasoma ventrally golden-red. Paratype with darker bluish coloration on head, mesosoma, and T1; lighter greenish-rosy on T2 and T3. Mandibles brown, basally golden-green. Scape and pedicel metallic green, F1 basally slightly metallic, remaining flagellomeres black. Legs green, tarsi brown. Tegulae green. Wings hyaline, brownish around radial sector, veins brown. Vestiture . Pubescence on vertex and dorsally on mesosoma dense, long (1.8 MOD), erect and whitish setae; metasoma laterally with long, erect setae; on femora and tibiae with sparse, erect and long setae. Female . Unknown. DISTRIBUTION. Tajikistan . ETYMOLOGY. The specific epithet niehuisi (masculine name in genitive case) is named after Prof. Dr. Oliver Niehuis (Freiburg i. Br., Germany ) in recognition of his work on cuckoo wasps.
