Figs 10A–F View Fig , 14A, B View Fig

SPECIMENS EXAMINED. Holotype – ♀, Russia: Tuva Rep., 20 km SSW

Erzin , Tore-Khol’ Lake, 3.VII 2013 ( VL, MP) [ ZIN]. Allotype – ♂, same locality,

30.VI 2013 [ZIN]. Paratypes: 2 ♀, 2 ♂, same locality, 30.VI–3.VII 2013 [ZIN, IBSS,

metasoma, dorsal view; F – metasoma, dorso-lateral view. Scale bar = 0.5 mm.

DIAGNOSIS. Hedychridium proshchalykini sp. n. is closely related to H. leleji

sp. n. for face with broad cross-ridging and structure of genital capsule. It differs from H. leleji sp. n. through: coloration without violet stripes on pronotum and a large dorso-medial black area on T1 and T2; punctuation on pronotum, mesonotum,

mesoscutellum and metascutellum shallower and scattered, with irregular sized punctures; pronotum and mesonotum, seen in posterior view, with punctuation rugulose, somehow forming transverse striae or wrinkles among punctures ( Fig. View Fig

10D); rugulose punctures on mesoscutellum outline longitudinal wrinkles, more obvious than in H. leleji sp. n. ( Fig. 10D View Fig ); genitalia ( Fig. 14A, B View Fig );

DESCRIPTION. Body length 3.7–4.8 mm. Fore wing length 2.5–2.8 mm.

Female. OOL = 2.8 MOD; POL = 2.0 MOD; MS = 0.4 MOD; relative length of P:

F1: F2: F3 = 1: 1.1: 0.7: 0.6.

Head. Vertex and frons with shallow, contiguous and medium-sized punctures

(0.3–0.5 MOD); face with punctures of the same size also along eye margin; on lower half of face, punctures interspersed with broad cross-ridging originating from middle line of scapal basin; face with deep and broad median sulcus, connecting midocellus to clypeus ( Fig. 10A View Fig ). Punctuation on post-ocellar vertex smaller, shallower, with impunctate interspaces. Ocellar triangle isosceles.

Mesosoma. Pronotum, mesoscutum and mesoscutellum with rugulose, shallow punctures; on pronotum irregularly sized, contiguous ( Fig. 10C View Fig ); on posterior half of mesoscutum shallow to almost vanishing, with transverse wrinkles between punctures ( Fig. 10D View Fig ). Mesoscutellum with rugulose punctures forming longitudinal wrinkles ( Fig. 10D View Fig ). Metascutellum with areolate-reticulate punctures and mesopleuron with large foveate punctures. Propodeal teeth triangular, with angle slightly pointing backward. Forewing basal vein as long as RS stub, gently arched.

Metasoma. T1 and T2 with minute, scattered punctures, 1–3 PD apart, T3 with denser punctures, partially transversely rugulose; T2 laterally with double punctuation. T3 posterior margin with very narrow brownish rim.

Coloration. Frons mostly metallic red and face bronze to coppery; broad median sulcus blue to blackish, contrasting with the rest of face; mid ocellar area and occipital area greenish. Pronotum metallic red; pronotal collar and propleuron dark blue to violet; mesoscutum and mesoscutellum red; mesopleuron and metanotum greenish,

propodeum and ventral surface bluish. Metasoma metallic red, postero-medially on

T1 and antero-medially on T2 black; sterna black with an ill-defined greenish sheen on S2. Scape and pedicel shiny black, with metallic sheen, flagellum blackish.

Tegulae brown, non-metallic. Wings medially light amber.

Vestiture. Body dorsally with sparse, whitish, long setae (1.5 MOD); mesosoma and metasoma laterally with very long setae (2.0 MOD). Legs with erect setae (1

MOD).

Male. Similar to female. Genital capsule as in Fig. 18A, B.

DISTRIBUTION. Russia (Tuva Rep.)

ETYMOLOGY. The specific epithet proshchalykini (masculine name in genitive case) is dedicated to M. Yu. Proshchalykin (Vladivostok, Russia), expert hymeno-

pterologist and collector of great part of the studied material of these articles.
