DIAGNOSIS. Hedychridium leleji sp. n. and the following two species, H.

loktionovi sp. n. and H. proshchalykini sp. n. belong to a distinct species group or subgroup characterized by short and stout genital capsule ( Fig. 14A–G ), scapal basin microridged to broadly cross-ridged and unusual body coloration. Very likely,

H. uvarovi Semenov, 1967 is another member of this group, whose genitalia are not yet studied. Hedychridium leleji sp. n. is immediately recognizable for the peculiar body color: head blue to violet, in dorsal view; frons metallic red, face red to greenish;

ocellar area and occipital area dark blue to violet; propodeum red with two posterolaterally violet stripes, more or less medially separated, mesoscutum and mesoscutellum red, mesopleuron and metanotum red to greenish-red, propodeum and ventral surface bluish to blackish; metasoma dorsally red and ventrally black with an undefined bluish sheen on S2. Moreover, it can be recognized through face with broad cross-ridging from medial line of scapal basin to eye margin. It can be separated from H. proshchalykini sp. n. through simple sculpture of metanotum, without type, ♀: B – mesosoma, lateral view; C – mesosoma, dorsal view; D – mesosoma, dorsal view; E – metasoma, dorsal view; F – metasoma, lateral view. Scale bar = 0.5 mm.

longitudinal wrinkles (vs. rugulose in proshchalykini ), and from H. loktionovi sp. n.

through body coloration with violet stripes on pronotum (uniformly green in H.

loktionovi) and T2 uniformly red dorsally (vs. black, lustreless on T1 and T2).

DESCRIPTION. Body length 4.0–5.0 mm. Fore wing length 2.8–3.2 mm.

Female. OOL = 2.2 MOD; POL = 1.8 MOD; MS = 0.3 MOD; relative length of P:

F1: F2: F3 = 1: 1.3: 0.8: 0.7.

Head. Vertex and frons with contiguous, medium sized punctures (0.3–0.5 MOD);

face with punctures of the same size, along eye margin, interspersed with crossridging; scapal basin with broad cross-ridging, originating from middle line and reaching eye margin. Facial longitudinal midline deep and connecting midocellus to clypeal margin or nearly so. Punctuation on post-ocellar vertex coarse ( Fig. 9C ).

Ocellar triangle isosceles.

Mesosoma. Pronotum punctures irregularly sized, coarse, mostly shallow and contiguous. Mesoscutum and mesoscutellum with similar punctures; on mesoscutellum slightly rugulose ( Fig. 9D ). Mesopleuron with large, coarse, contiguous punctures

( Fig. 9B ). Metascutellum with areolate-reticulate punctures. Propodeal teeth triangular, with angle pointing outside ( Fig. 9D ). Forewing basal vein 1.2 times as long as RS stub, gently arched.

Metasoma. T1 and T2 with minute, sparse punctures, 1–3 PD apart, uniformly distributed ( Fig. 9E ); T2 laterally with double punctuation ( Fig. 9F ). T3 with denser punctures; T3 posterior margin with narrow brownish apical rim.

Coloration. Frons metallic red; face red to greenish; ocellar area and post-ocellar vertex dark blue to violet; genae from violet to greenish. Propodeum red with two postero-laterally violet stripes, more or less medially separate; mesoscutum and mesoscutellum red; mesopleuron and metascutellum red to greenish; propodeum and legs bluish to blackish; metasoma dorsally red and ventrally black, with an undefined bluish sheen on S2. Scape and pedicel shiny black, with metallic sheen;

flagellum blackish. Tegulae brown, non-metallic. Wings medially lightly amber.

Vestiture. Body dorsally with sparse, whitish, short setae (1 MOD), mesosoma and metasoma laterally with long setae (1.5 MOD) ( Fig. 9F ). Legs with erect setae

(1 MOD).

Male. Similar to female. Genital capsule as in Figs 14C, D .

DISTRIBUTION. Russia (Tuva Rep.).

ETYMOLOGY. The specific epithet leleji (masculine name in genitive case) is dedicated to Arkady S. Lelej (Vladivostok, Russia), curator at the Federal Scientific

Centre of the East Asia Terrestrial Biodiversity, expert hymenopterist and collector of part of the studied material in these articles, who entrusted the first author in the study of the Russian Chrysididae .
