Hedychridium karakolense sp. nov.

( Figs 1–4 , 5–6)

Holotype. Female , Kyrgyzstan, Northern Tian Shan , Issyk Kul Region, Eastern Terskey Ala Too Range, 4 km S of Teplokluchenka Vill., 25 km SE of Karakol, 2200 m, 15–30.VIII.2000 ( ZIN).

Paratypes. Kyrgyzstan: 3 females, same data as for holotype ( GLAC; PRC) ; 1 male, Naryn Too Range, Krysu gorge or canyon, 15.VII.1987, leg. S. Ovchinnikov ( IBPB) .

Description. Female: body length 7.0– 7.3 mm; fore wing length 4.4 mm; OOL = 1.95 MOD; POL = 1.4 MOD; MS = 0.9 MOD; relative length of P:F1:F2:F3 = 1.0:1.4:0.9:0.8.

Head. In frontal view, head distinctly wider than high, for the narrowest interocular distance 1.25 times longer than distance between lower margin of midocellus and antennal sockets. Frons finely and densely punctate, with small (0.2 MOD) subcontiguous punctures; punctation on face with similar punctures, medially transversally irregularly wrinkled; face asetose; subantennal space 1.0 MOD; ocellar triangle isosceles; in dorsal view, temples from posterior margin of the eye to occiput, rounded and enlarged (> 2 MOD). F1 3.3 times long as wide; mandibles toothed.

Mesosoma. Pronotal anterior margin with carina interrupted. Overall sculpture with dense punctures, generating a dull body reflection. On pronotum and anterior part of mesoscutum with small (0.1–0.2 MOD) punctures; on posterior part of mesoscutum with double punctation, with relatively larger punctures (0.3 MOD) and polished interstices (0.1–1.0 PD); on mesoscutellum with double punctation and small polished interstices anteriorly and subcontiguous posteriorly; notauli and parapsidal furrows deep and complete. Metanotum distinctly elongate, 1.4 times longer than pronotum, with large (0.5 MOD), foveate-reticulate punctures. Mesopleuron with dense and rounded punctures. Propodeal teeth short, triangular. Forefemur unmodified not expanded or angulate, hindfemur with an elongate and wide depression on inner surface; hindtarsi unmodified, with second and third tarsomere subequal in length; fifth tarsomere as long as third+fourth. Tarsal claws with a very small submedian tooth, hardly visible. Forewing outer veins scarcely visible, medial vein gently curved; Rs stub longer than R1.

Metasoma. Metasomal terga with minute, shallow, even and dense punctation, punctures 1 PD apart, with polished intervals ( Figs 1, 3 ). Third tergum with narrow, translucent apical rim on posterior margin. First sternum impunctate; second sternum with scattered double punctation; third tergum with dense small punctures; laterotergites minutely and densely punctured on outer side.

Colouration. Head entirely blue without red, purplish or coppery colours; pronotum, excluding pronotal collar, mesoscutum, metascutellum red to purplish; mesopleuron blue to light blue, without red or coppery reflections; rest of mesosoma blue, black ventrally; metasoma purplish dorsally and blackish ventrally. Legs metallic green to blue; tarsi brownish.

Vestiture. Erect, whitish setae on head, distinctly long (2 MOD) laterally, and very long setae (up to 2.5 MOD) on coxae, trochanters, femora, the second metasomal sternum and the apical margin of the third metasomal tergum.

Male. Body length 6.7 mm; OOL = 1.95 MOD; POL = 1.4 MOD; MS = 0.5 MOD; relative length of P:F1:F2:F3 = 1.0:1.7:1.0:0.8. Similar to female, but apical margin of the third metasomal tergum more rounded (Fig. 5). Genital capsule as in Fig. 6.

Etymology. The specific epithet karakolense refers to the main type locality in Kyrgyzstan, nearby the Issyk Kul Lake.

Distribution. Kyrgyzstan.
