SPECIMENS EXAMINED. Holotype – ♀: Tajikistan: W Pamir, Rushan Dst.,

3400 m, 20–30.VII 2015, leg. V . Gurko & c. [ZIN].

DIAGNOSIS. Chrysis gurkoi sp. n. belongs to the C. succincta species group. It shows the typical habitus of Alpine species, with flattened body; shallow and sparse punctation; long erect setae on body and legs; darkened colouration. It is separated from all the other species of his group by its habitus, colouration, narrow ocelli and atypical short apical teeth of the T3.

bitus, lateral view; 13 – metasoma, postero-lateral view; 14 – metasoma, ventral view. Scale bar = 1.0 mm.

DESCRIPTION. Female. Body length 7.1 mm. Fore wing length 4.2 mm. OOL

= 1.8 MOD; POL = 1.8 MOD; MS = 1.5 MOD; relative length of P:F1:F2:F3 =

1.0:1.5:0.9:0.8.

Head. In full face view, length 1.5 mm, width 2.0 mm. Apex of clypeus regular-

ly concave; TFC faint; scapal basin deeply hollowed, medially polished; laterally with small punctures; frons and vertex with small to medium-sized punctures; on frons subcontiguous and without polished interstices, sparser on occiput; largely polished ahead of midocellus and laterally to posterior ocelli. Subantennal space less than 1.0 MOD. Genal carina complete and extending to mandible joint, malar spaces minutely punctate. Mandible toothless.

Mesosoma. Length 2.6 mm; width (PPW) 1.7 mm. Pronotum relatively short,

with distinct anteromedian groove, as long as ½ of pronotal length; with punctures of different diameter and tiny punctures on interstices. Mesoscutum with shallow,

sparse punctures, and large polished interstices; on lateral lobes with tiny punctures on interstices; notauli and parapsidal lines complete, as lines of deep punctures,

decreasing from posterior to anterior margin. Mesoscutellum anteromedially largely polished, with shallow, small punctures, posteromedially larger; punctures smaller and denser towards axillary trough. Metanotum anteromedially polished, posterolaterally with dense, uneven, subreticulate punctures. Mesopleuron with mediumsized punctures; short and deep episternal sulcus. Propodeal teeth unmodified,

subparallel, pointing backwards.

Metasoma. Length 3.2 mm. Punctation on T1 with small, dense, geminate punctures, micropunctate on polished interstices. T2 malformed; anteromedially with smaller and denser punctures, becoming scattered towards margins; longitudinal medial carina present. T3 with longitudinal median carina scarcely visible; apical margin with four short, triangular teeth; medial teeth as angles, narrower; lateral ones pointed; post pit row area medially about 1.0 MOD long; S2 with fused, large black spots, covering ¾ of sternum length.

Coloration. Typical colour pattern of Chrysis succincta Linnaeus, 1767, with rosy colour instead of red; propodeum and mesopleuron anteriorly rosy, apical margin of metasomal terga greenish. Body ventrally rosy to purplish. Mandibles brown, basally metallic green and subapically lighter. Scape and pedicel metallic green, flagellum black. Legs green to purplish; tarsomere brown. Tegulae brown.

Wings hyaline with dark brown nervures.

Vestiture. Long, erect, whitish setae all over body and legs, laterally longer, up to 2.5–3.0 MOD.

Male. Unknown.

DISTRIBUTION. Tajikistan.

ETYMOLOGY. The specific epithet gurkoi (masculine name in genitive case)

is named after the collector of this species, Vladimir O. Gurko ( Ukraine).
