SPECIMENS EXAMINED. Holotype – ♀: Kyrgyzstan: S slope of Baybiche

Too (Naryn region), 2800 m, 6–7.VIII 1995, leg. D. Milko [ZIN], specimen previously kindly donated by Maya Linsenmaier to P. Rosa.

DIAGNOSIS. Chrysis milkoi sp. n. belongs to the C. bihamata species group. It can be easily separated from all other known species by its body coloration, which is identical with C. calimorpha Mocsáry, 1882 of the C. pulchella group. Yet C.

milkoi sp. n. is separated by ill-defined TFC, face distinctly elongate, apical margin of T3 with two angulated lateral teeth and medially almost straight, with two weak undulations (vs. well marked TFC, with elongate branches toward mid-ocellus, face squarish, apical margin of T3 biconvex, with an apicolateral angle, and lateral edge with a median tooth in middle, followed by a well-marked concavity in C. calimorpha).

DESCRIPTION. Female. Body length 9.0 mm. Fore wing length 4.0 mm. OOL

= 2.2 MOD; POL = 1.9 MOD; MS = 1.0 MOD; relative length of P:F1:F2:F3 =

1:1:0.9:0.8.

Head. In full face view, length 3.0 mm, width 2.1 mm. Clypeus largely black and apically with thickened edge; straight at apex; subantennal space longer than

1.0 MOD. TFC slightly raised, vaguely U-inverted; scapal basin deeply hollowed,

largely impunctate, laterally with irregular small to medium-sized punctures; frons and vertex with reticulate small to medium-sized punctures, without polished interstices; lateral to ocelli with large impunctate area. Malar space about 1.0 MOD,

shorter than F1, convergent. Genal carina complete and extending to mandible joint.

Mandible subapically toothed.

Mesosoma. Length 3.7 mm; width (PPW) 2.3 mm. In lateral view, mesosomal segments well separated by deep intersegmental sutures. Pronotum with weak anteromedian groove and double punctation. Mesoscutum with reticulate, mediumsized punctures, basally larger among notauli; on lateral lobes sparser, with double punctures; notauli and parapsidal lines complete, notauli as deep lines. Mesoscutellum anteromedially polished, posterolaterally with irregular subreticulate punctures.

Metascutellum red, contrasting with blue anterior suture, blue axillary trough and propodeum; punctation reticulate and smaller than mesoscutellum. Mesopleuron with deep, complete episternal sulcus and even punctures. Propodeal teeth divergent.

Metasoma. Length 3.7 mm. Punctation on T1 with small (0.3–0.4 MOD), sparse punctures, 1–3 PD apart, densely micropunctate on interstices. T2 anteromedially with double punctures, becoming largely scattered towards margins; longitudinal medial carina present. T3 with subconfluent punctures; longitudinal median carina present; apical margin with two triangular lateral angles and two median weak undulations; pits of the pit row small and shallow; post pit row area about 1 MOD long; S2 with large, suboval black spots, medially close, not fused, separated by a narrow metallic line and covering about 2/3 of entire sternum length.

Coloration. Head, mesosoma laterally and ventrally, and propodeum blue with green or golden green reflections; pronotum, mesonotum and metascutellum red;

T1, T2 and T3, before pit row, red; apical margin of T3, from pit row, contrasting blue; metasoma ventrally greenish. Mandibles dark brown, basally metallic green.

Antennae black, with a feeble purple reflection on scapus. Legs green; tarsomere dark brown. Tegulae brown. Wings darkened with dark brown nervures.

Vestiture. Long, erect, whitish setae all over body and legs, laterally longer, up to 2.0 MOD.

Male. Unknown.

tus, lateral view; 21 – head, frontal view; 22 – metasoma, postero-lateral view. Scale bar =

1.0 mm.

ETYMOLOGY. The specific epithet milkoi (masculine name in genitive case) is named after the Dmitry A. Milko (Bishkek, Kyrgyzstan), for the help provided during the author stay at the Institute of Biology and Pedology of the National

Academy of Sciences of Kyrgyzstan.
