DIAGNOSIS. Hedychridium loktionovi sp. n. is related to H. proshchalykini sp.

n., but can separated through body coloration, almost uniformly greenish to bronze,

including propodeum (vs. metallic red, with bluish contrasting matanotum and propodeum in H. proshchalykini sp. n.); S2 black with large, defined red to greenish median spot (vs. S2 black with ill-limited greenish area); face punctuation with large punctures and weak cross-ridging, limited to the median part (vs. lower half of face with punctures interspersed with broad cross-ridging); punctuation on mesoscutellum contiguous, without transverse wrinkles; punctuation on metascutellum rugulose without longitudinal wrinkles; genitalia differently shaped

( Figs. 14E, F ).

DESCRIPTION. Female. Body length 4.0– 4.5 mm. Fore wing length 3.0–3.2

mm. OOL = 2.5 MOD; POL = 2.0 MOD; MS = 0.6 MOD; relative length of P: F1:

F2: F3 = 1: 1.3: 0.9: 0.8.

Head. Vertex and front with deep, defined, contiguous and medium-sized punctures (0.3–0.5 MOD); face with punctures of the same size on upper scapal basin and along eye margin; scapal basin medially cross-ridged, only partially interspersed in punctures ( Fig. 11A ); face with deep and broad median sulcus connecting midocellus to clypeus. Punctuation on post-ocellar vertex smaller, irregular, denser,

without polished interspaces. Ocellar triangle isosceles.

Mesosoma. Pronotum with irregularly sized, contiguous, coarse and rugulose punctures. Mesoscutum and mesoscutellum with smaller punctures, interspaces slightly rugulose or polished ( Fig. 11C ). Mesopleuron with large, coarse and contiguous punctures ( Fig. 11B ). Metascutellum with areolate punctures ( Fig. 11D ).

Propodeal teeth triangular, with angle pointing outside. Forewing basal vein two-

thirds as long as RS stub, gently arched.

Metasoma. T1 and T2 with minute, scattered punctures, 1–4 PD apart ( Fig. 11E ),

T3 with denser punctures; T1 and T2 laterally with double punctuation. T3 posterior margin with very narrow brownish rim ( Fig. 11F ).

Coloration. Frons and face green to bronze; broad median sulcus blue to blackish;

ocellar area, post-ocellar vertex and occipital area bluish; mesosoma green with coppery reflections; propodeum mostly unicolor, darker to bluish on the lower and posterior part; metasoma greenish, laterally coppery, dorsally with extensively black spot on T1 and T2; sterna black with large and defined greenish-coppery median spot. Scape and pedicel metallic green, flagellum black, Tegulae brown. Wings slightly infuscate.

Vestiture. Head and mesosoma dorsally with dense, whitish, erect and long setae

(1.5 MOD); metasoma dorsally with sparser, appressed, shorter setae (1.0 MOD);

metasoma postero-laterally with long, erect whitish setae (2.0 MOD). Femura and tibiae with long, erect setae (> 1.5 MOD).

mesosoma, lateral view; C – mesosoma, dorsal view; D – mesosoma, detail, dorsal view; E –

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

mesosoma, lateral view; C – mesosoma, dorsal view; D – metasoma, dorso-lateral view; E –

metasoma, dorsal view; F – metasoma, ventral view. Scale bar = 0.5 mm.

Male. Similar to female. Genital capsule as in Fig. 14E, F .

DISTRIBUTION. Russia (Tuva Rep.).

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

is dedicated to Valery M. Loktionov (Vladivostok, Russia), researcher of Siberian

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