DIAGNOSIS. Chrysis chalybeia sp. n. belongs to the C. bihamata species group.

It is related to C. branicki Radoszkowski, 1876 from Egypt, whose type has been recently found in Berlin and not in Krakow, where it was supposed to be housed. C .

chalybeia sp. n. can be easily separated by elongate MS (2.0 MOD); body sculpture with smaller, relatively shallow punctures, and shining interstices; mesoscutellum anteromedially with small, dense micropunctures; T3, in dorsal view, triangularly shaped; in lateral view, slightly depressed before pit row; elongate post pit row area,

longer than 1.0 MOD; exceptionally elongate genitalia ( Fig. 49 ). C. branicki con-

versely has short MS (about 1.0 MOD); all over body with large and subreticulate punctures, without shining interstices, including mesoscutellum; T3, in dorsal view,

subrectangular and convex before pit row; in dorso-lateral view, short post pit row area (1.0 MOD); genitalia unmodified.

DESCRIPTION. Male. Body length 7.2 mm. Fore wing length 4.8 mm. OOL =

2.4 MOD; POL = 2.0 MOD; MS = 2.0 MOD; relative length of P:F1:F2:F3 = 1.0:

1.3:0.9:0.9.

Head. In full face view, length 1.7 mm, width 1.9 mm. Apex of clypeus medially arched; TFC faint; scapal basin slightly hollowed, fully punctate, with no clear se-

paration from frontal punctures; frons and vertex with small, reticulate punctures,

without polished interstices. Malar spaces about 2.0 MOD, convergent. Subantennal distance about 1.0 MOD. Genal carina complete and extending to mandible joint,

malar spaces minutely punctate. Mandible with inner tooth.

Mesosoma. Length 2.5 mm; width (PPW) 1.8 mm. Pronotum relatively short,

along mid-line as long as metanotum, with anteromedian groove; punctures uneven,

with tiny punctures on interstices. Mesoscutum with irregular, coarse punctures

(0.1–0.4 MOD), partly confluent; narrow, polished interstices; on lateral lobes with smaller, irregular punctures; notauli and parapsidal lines complete, notauli visible as lines of small punctures. Mesoscutellum anteromedially densely and closely micropunctate as in the male of Holopyga fervida (Fabricius, 1781); laterally and posteriorly with shallow, small to medium-sized punctures, and broad, shining interstices. Metanotum anteromedially with large fovea; punctation coarse, denser, with uneven,

subreticulate punctures. Mesopleuron with subconfluent medium-sized punctures,

with deep, very short, episternal sulcus. Propodeal teeth divergent, pointing backwards.

Metasoma. Length 3.3 mm. Punctation on T1 with small (0.3–0.4 MOD), sparse punctures, 1–3 PD apart, densely micropunctate on interstices. T2 with double punctation, with punctures becoming scattered towards margins; longitudinal medial carina present. T3 with shallow punctures, medially subconfluent, with tiny punctures on interstices; longitudinal median carina scarcely visible; apical margin with two triangular lateral teeth and two median undulations; post pit row area longer than 1.0 MOD long; S2 with large, suboval black spots, medially close, not fused, separated by a narrow metallic line and covering about half sternum length.

Coloration. Chrysis chalybeia sp. n. is entirely blue steel, with green reflections on head, dorsally on mesosoma and posteriorly on metasomal terga. Body ventrally greenish. Mandibles dark brown, basally metallic green. Scape and pedicel metallic green, flagellum black. Legs green; tarsomere dark brown. Tegulae metallic blue.

Wings slightly darkened, with dark brown nervures.

Vestiture. Long, erect, whitish setae all over body and legs, laterally longer, up to 2.5 MOD.

Female. Unknown.

DISTRIBUTION. Tajikistan.

ETYMOLOGY. The specific epithet chalybeia (feminine, adjective) is derived from Latin chalybeius, meaning “made of steel”.
