SPECIMENS EXAMINED. Holotype – ♀, Russia: North Caucasus : Stavropol

Terr., Mineralnye Vody, St. Podkumok, 2.VIII 2006 (N. Vinokurov) [ZIN].

DIAGNOSIS. Chrysis vinokurovi sp. n. is a remarkable species, one of the largest in the succincta species-group (10 mm long). It shows the body coloration of

C. gribodoi spilota Linsenmaier, 1959 ( Fig. 7A ), with typical coloration pattern of

C. succincta and purple-blackish spots on T1 and T2. Nevertheless, it can be easily separated for the peculiar tridentate apical margin of T3 ( Fig. 8E ) and the black spots on S2, covering most of the sternite length ( Fig. 8F ). This tridentate apical margin is observed in the Cypriot endemism C. mavromoustakisi Trautmann, 1929 ( Fig.

7B) too. The new species differs from C. mavromoustakisi by body coloration (mesosoma largely metallic red in C. mavromoustakisi ) and metasoma punctuation, with small and dense punctures (vs. large, foveate and contiguous in C. mavromoustakisi ).

Chrysis vinokurovi sp. n. belongs to the same subgroup of C. gribodoi Abeille de

Perrin, 1877, C. cohaerea Linsenmaier, 1959 and C. pseudogribodoi Linsenmaier,

1959. It is separated from these relative species through shape of T3, black spots on

S2 and punctuation of metasoma.

DESCRIPTION. Body length 10.0 mm. Fore wing length 6.0 mm. Female.

OOL = 1.8 MOD; POL = 2.4 MOD; MS = 1.0 MOD; relative length of P: F1: F2:

F3 = 1.0: 1.5: 0.8: 0.7.

Head. Vertex and frons with small, contiguous punctures; TFC irregular, barely raised on interspaces among punctures, thus appearing double and with ramifications

( Figs 7A , 8A ); scapal basin medially polished and laterally punctate, with minute and dense punctures; subantennal space about 1.0 MOD; anterior margin of clypeus medially emarginate, laterally with thickened brownish rim; in frontal view, malar spaces slightly convergent. Genal carina fully developed to mandible.

♀, Cyprus; C, D – C. mokrousovi Rosa , sp. n. (C – holotype, ♀; D – paratype, ♂); E, F – C .

lyda sp. n. (E – holotype, ♀; F – paratype, ♂). A–C, E – habitus, dorsal view; D, F – genital capsule. Scale bar for A–C, E = 1.0 mm, D, F = 0.5 mm.

Mesosoma. Pronotal groove relatively deep and wide, almost reaching 2/3 of pronotum length; punctuation on pronotum with small, contiguous punctures; on mesoscutum with punctures of larger size, increasing in size towards posterior margin; on mesoscutellum and metascutellum with minute punctures on interspaces; mesoscutellum antero-medially impunctate and with minute punctures,

darker to black; propodeal teeth divergent ( Fig. 7A ). Episternal and scrobal sulci with deep, foveate punctures ( Fig. 8B ).

lateral view; C – metasoma, dorsal view; D – metasoma, lateral view; E – T3, dorsal view;

F – metasoma, ventral view. Scale bar = 1.0 mm.

Metasoma. Punctuation on T1 with small punctures, 1 PD apart ( Fig. 8C );

postero-laterally and laterally double, with minute punctures on interspaces; on T2

dorsally denser (<1 PD apart) ( Fig. 8C ), laterally double and more spaced (1–2 PD

apart), with larger and lacunose punctures ( Fig. 8D ); on T3 with larger punctures contiguous and bearing long, whitish setae; pit row with deep and elongate pits;

median teeth on apical margin of T3 fused, as a result apical margin appears tridentate ( Fig. 8E ); this median tooth extending further posteriorly than lateral teeth; lateral teeth as blunted corners ( Fig. 8D ).

Coloration. Body colour as in Chrysis succincta Linnaeus , with metallic blue head and mesosoma; red to golden red on anterior margin of pronotum, mesoscutum,

antero-lateral corners of mesoscutellum; metasoma red with antero-median dark purplish spot on T1 and T2; apical margin of T3, after pit-row, dark purple to black.

Black spots on S2 large and medially fused, covering 4/5 of sternite and not strongly oblique posteriorly. Tegulae dark brown, without metallic reflections; tarsi dark brown; scape, pedicel and F1 basally metallic green, rest of flagellum black. Hind wings smoky.

Vestiture. Body covered with whitish, short, erect setae (1.0 MOD), laterally longer (up to 1.5 MOD); laterally on T3 up to 2.0 MOD. Legs with erect, whitish setae,

shorter on foretibiae (1.0 MOD), longer on mid- and hindtibiae (up to 1.5 MOD).

Male. Unavailable for this study.

DISTRIBUTION. Russia (Stavropol Territory).

ETYMOLOGY. The specific epithet vinokurovi (masculine name in genitive case) is named after Nikolaj B. Vinokurov ( Mineralnye Vody , Russia), who collected the holotype .

REMARKS. This species was misidentified by Vinokurov (2013) as Chrysis mavromoustakisi Trautmann, 1929 .
