SPECIMENS EXAMINED. Holotype – ♀, Kazakhstan: Aktyubinskaya distr. ,

Mugodzharj Mts. , 15 km N Emba steppe, 11. VI 1985, leg. M. Nesterov [ ZIN] .

Paratype: 1♀, same locality and collecting data [ PRC] .

DIAGNOSIS. Hedychridium kilimniki sp. n. belongs to the H. ardens group, H.

femoratum subgroup, for non-metallic, yellowish tibiae and tarsi. It is separated from other species for its peculiar coloration, with head and mesosoma dorsally matt red to coppery, yet notauli, axillary trough and propodeum contrasting blue; metasoma metallic red with a large triangular black spot on second tergum (also face and metascutellum contrasting blue to green in H. femoratum Dahlbom, 1854, H. turanicum

Semenov, 1954, H. elegantulum du Buysson, 1887). It is separated from the above species also for: notauli and other sutures distinctly deeper ( Fig. 16 ); mesosoma punctation dense and irregular; punctation on second and third sternum dense and double, with a metallic basomedial spot on second sternum (sterna wholly black in the above species).

DESCRIPTION. Body length 4.0–5.0 mm. Fore wing length 2.8–3.5 mm.

Female. OOL = 2.6 MOD; POL = 2.4 MOD; MS = 1.0 MOD; relative length of

P:F1:F2:F3 = 1.0:1.4:0.7:0.6.

Head. Frons, vertex, face among scapal basin and eye with irregular, mediumsized punctures (0.3 MOD), nearly contiguous, with small to tiny punctures on interstices; scapal basin transversely striate. Ocellar triangle isosceles; midocellus anteriorly, and posterior ocelli laterally sunken. Subantennal space about 1.0 MOD;

clypeal margin with thickened rim (up to 1.0 MOD). Mandibles apically toothed;

the details could not be examined, due to the impossibility to open the mandibles without risk to break them.

Mesosoma. Mesosoma with irregularly sized, contiguous to confluent punctation,

generating a matt colour effect, similarly to the common H. coriaceum (Dahlbom,

1854). Notauli visible as rows of deep, elongate, blackish-blue foveae, contrasting with the rest of mesoscutal coloration. Axillary trough partly dark blue, also contrasting with red mesoscutellum and metascutellum. Metascutellum with foveate-

reticulate punctures, and irregular foveae. Propodeal teeth sharp, curved, pointing outwards and slightly backwards. Inner side of hindtibiae at apex with a large, sub-

triangular dark pit, extending over one third of the tibia length.

Metasoma. First and second tergum with even and minute punctures, evenly spaced dorsally, almost contiguous laterally. Apical margin of third tergum with narrow hyaline rim (0.5 MOD). Second and third sternum unusually deeply and densely punctate, with double punctures.

16 – mesosoma, dorsal view; 17 – head, frontal view; 18 – metasoma, dorsal view; 19 –

metasoma, dorso-lateral view; 20 – metasoma, ventral view. Scale bar = 1.0 mm.

Coloration. Body metallic red to coppery; dark blue to blackish on notauli,

axillary trough, and propodeum. Metasoma metallic red with a large triangular black spot on second tergum; ventrally black, with a triangular coppery spot on second sternum. Mandibles brown, medially testaceous. Scape coppery, pedicel and flagellum dark brown. Legs with coxae and outer side of femora coppery, the rest yellowish testaceous. Wings slightly smoky, without darkened margins.

Vestiture. Body dorsally covered by dense, whitish, short setae (less than 1 MOD);

ventrally, on lower face and femora with long setae (> 1 MOD).

Male. Unknown.

DISTRIBUTION. Kazakhstan.

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

is named after A.N. Kilimnik (Odessa, Ukraine), who firstly recognized this species as still undescribed.
