DIAGNOSIS. Chrysis belokobylskiji sp. n. belongs to the C. pulchella species group for: TFC strongly raised, M-like; F1 markedly elongate; T2 and T3 with moderate medial ridge; male genital capsule with slender gonocoxae ( Fig. 51 );

shape of the apical margin of T3; large, quadrangular, almost fused black spots on

S2. C. belokobylskiji sp. n. is close related to C. personata Semenov, 1967 for the bicoloured body, yet it can be separated by: smaller metasomal punctation, with scattered punctures and shining interstices; apical margin of the last tergum with basal tooth and lateral angle blunt, close to each other, medially almost straight with shallow undulations ( Fig. 7–10 ), (vs. metasoma with large and coarse punctures,

almost without interstices; apical margin of last tergum with marked basal and lateral teeth, medially biconvex in C. personata).

DESCRIPTION. Female. Body length 6.2–6.5 mm. Fore wing length 4.0–4.5

mm. OOL = 1.8 MOD; POL = 2.0 MOD; MS = 1.1 MOD; relative length of P:F1:

F2:F3 = 1.0:1.3:1.0:1.0.

Head In full face view, length 1.6 mm, width 1.9 mm. Apex of clypeus boomerang-shaped, bordered with a thick rim; TFC strong, M-like, with elongate branches almost habitus, lateral view; paratype ♀: 3 – habitus, dorsal view; 4 – habitus, lateral view. Scale bar

= 1.0 mm.

metasoma, postero-lateral view; paratype ♀: 8 – metasoma, posterior view; holotype ♀: 6 –

head, frontal view; 9 – metasoma, ventral view; 10 – metasoma, posterior view. Scale bar =

1.0 mm.

encircling mid ocellus; scapal basin hollowed, transversally finally striated (in a paratype only with slight and irregular wrinkles); laterally with small, aligned punctures, following the orientation of median wrinkles; frons and vertex with mediumsized, subcontiguous punctures; with polished area lateral to posterior ocelli and ahead of mid ocellus; deep small pit ahead of mid ocellus. Subantennal distance about 1.0. Genal carina complete and extending to mandible joint, malar spaces finely and minutely punctate. Mandible simple, without inner tooth.

Mesosoma. Length 2.3 mm; width (PPW) 1.5 mm. Pronotum anteromedially slightly depressed, without distinctive anteromedian groove; irregularly punctate,

with punctures of different diameter, denser at side; tiny punctures on interstices.

Mesoscutum with shallow punctures; polished, shining interstices, with sparse tiny punctures; notauli and parapsidal lines deep. Mesoscutellum anteromedially polished,

medially with sparser, small to medium (0.5 MOD) punctures; punctures smaller and denser towards axillary trough. Metanotum with denser, medium-sized, subreticulate punctures, without polished interstices. Mesopleuron with medium-sized,

subreticulate punctures; episternal sulcus faint or a simple depression. Propodeal teeth unmodified, pointing backwards.

Metasoma. Length 3.2 mm. Punctation geminate; scattered on T1, 1–2 PD apart,

densely micropunctate on interstices. T2 with similar geminate punctures, anterodorsally denser, laterally and posteriorly scattered; longitudinal medial carina visible.

T3 with dense punctation, similar in pattern to T2 ; longitudinal median carina scarcely visible; slightly transversely bulging before pit row; apical margin medially continuous to weakly undulate, with acute lateral angles (blunt in paratypes) and basolateral blunt angles; pit row with small (0.5 MOD) and slightly elongate pits; post pit row area about 1.0 MOD long; black spots on S2 square,

fused or medially with a very narrow purplish line.

Coloration. Head and mesosoma blue to green, metasoma red to greenish-golden.

Body ventrally green, reddish on third sternum. Mandibles light brown, with metallic green reflections at base and darkened at apex. Scape, pedicel and T1 basally metallic green, other flagellomeres blackish. Legs green, with brown tarsomere. Tegulae metallic green. Wings hyaline with light brown nervures.

Vestiture. Long (1.0–2.0 MOD), sparse, erect and whitish setae on frons, vertex,

mesosoma laterally, legs, metasoma laterally and ventrally.

Male. Similar to female, TFC only medially raised.

DISTRIBUTION. China (Qinghai), Tajikistan, Kyrgyzstan, Mongolia.

ETYMOLOGY. The specific epithet belokobylskiji (masculine name in genitive case) is named after Sergey A. Belokobylskij (St. Petersburg, Russia), who supported author’s studies on Russian Chrysididae for several years.
