DIAGNOSIS. Chrysis inconsueta sp. n. belongs to the succincta species-group. It’s a medium-sized species (6.5 mm long) recognizable for the combination of the following characteristics: coloration pattern (bluish mesosoma with greenish-golden reflections on frons, anterior margin of pronotum and mesoscutellum; mesoscutum flame red; metasoma flame red, medially darker, purplish to blackish, on T2 and T3);

punctuation (mesosoma with shallow punctures and large, polished interspaces, giving a shining appearance); T3 after pit row elongate (2 MOD long), impunctate, concolorous with the rest of T3; T3 apical margin with four short and obtuse teeth.

A similar mesosoma coloration and apical margin of T3 is observed in the female of Ch. kessleri Radoszkowski, 1877 . Nevertheless, Ch. kessleri has a different,

robust habitus, similar to Ch. grohmanni Dahlbom, 1854 , and like the latter, apical margin of T3, after pit row, metallic blue, contrasting with the red coloration of T3;

the punctuation of metasoma is coarse, with large and deep punctures.

From general habitus and shining sculpture, Ch. inconsueta appears more closely related to Ch. popovi Semenov , which differs for the fully green mesosoma,

without any red or golden area; shape of T3, with ovoid pits on pit row, short distance between pit row and apical margin and different shape of apical teeth. However, actual affinities will be clear only when the male will be known.

DESCRIPTION. Female. Body length 6.5 mm. Fore wing length 3.8 mm. OOL =

1.8 MOD; POL = 2.5 MOD; MS = 1.0 MOD; relative length of P: F1: F2: F3 =

1.0: 1.6: 0.7: 0.6.

Head. Vertex and frons with large (up to 0.5 MOD), contiguous punctures; TFC

faint; scapal basin impunctate, polished, with minute punctures along eye margin,

as well as on clypeus and malar spaces; subantennal space 1.0 MOD; in frontal view, malar spaces subparallel ( Fig. 10A ).

Mesosoma. Pronotal groove narrow, forming a deep sulcus, reaching 2/3 of pronotal length; pronotal punctuation posteriorly coarse, with deep, uneven punctures,

anteriorly with polished interspaces; mesoscutum with shallow and sparse (1 PD

apart) punctures of different size, with polished and shining interspaces;

mesoscutellum with similar punctures, larger and deeper, anyway with polished and shining interspaces ( Fig. 10C ); metascutellum with deep, foveate, round punctures,

not larger than those on mesoscutellum. Mesopleuron with deep episternal sulcus with deep, aligned and small foveae, the rest with irregularly sized punctures and shining interspaces.

soma, lateral view; C – mesosoma, dorsal view; D – metasoma, lateral view; E – metasoma,

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

Metasoma. Punctuation on T1 double and spaced (up to 1 PD apart), with shining interspaces; T2 dorso-medially with small, dense punctures, becoming larger towards lateral margins, smaller and shallower toward posterior margin, here and there with tiny punctures on interspaces ( Fig. 10E ); interspaces polished and shining ( Fig. 10D );

T3 with punctures of different sizes ( Fig. 10F ), larger on lateral margins; medially with a longitudinal line of tiny dots; pit row with deep, broad and round pits; area between pit row and apical margin elongate (2.0 MOD) and impunctate ( Fig. 10F );

T3 apical margin with four short and obtuse teeth, interval between median teeth half as long as interval between median and lateral tooth.

Coloration. Head and mesosoma light to dark blue, darker to blackish on ocelli area, occipital area and genal carina; with golden reflections on clypeus and frons;

anterior margin of pronotum without red marks, laterally of the anteromedial groove with golden reflections; mesoscutum flame red; mesoscutellum golden-

green; metascutellum blue, lighter medially; mesopleuron blue with greenish reflections. Metasoma red; dorso-medially purplish on T1 and T3, and purplish to blackish on T2. Metasoma metallic red ventrally; S2 with black spots medially fused, with almost straight posterior margins, covering about 2/3 of sternum length.

Tegulae brown, without metallic reflections; tarsi brown; scape metallic green,

pedicel and flagellum black. Wings hyaline, with dark brown veins.

Vestiture. Setae brownish, dense, erect and elongate (1.5 MOD) on head and dorsally on mesosoma; ventrally with longer (more than 2.0 MOD) and whitish setae;

femora and tibiae with thick, erect and long setae (2.0 MOD). Metasoma laterally and posteriorly with very long, whitish setae (up to 3.0 MOD).

Male. Unknown.

DISTRIBUTION. Russia (Altai Rep.).

ETYMOLOGY. The specific epithet inconsueta (feminine, adjective) is given for the unusual combination of color pattern, elongate and impunctate area after the pit row and shape of apical margin of T3 with four teeth.
