SPECIMENS EXAMINED. Holotype – ♀, Russia: Krasnodar Terr., vill. Sennoy ,

25.VI 2012 ( MM) [ZIN]. Paratypes: Stavropol Terr., Mineralnye Vody, St. Podkumok , white pan trap , 26–29.VI 2006, 1♂, 1♀ (N. Vinokurov); env. Kizlovodsk,

4.VIII 2006, 1♂, 1♀. (N. Vinokurov); env. Kizlovodsk, St. Podkumok, 21.VI 2006,

1♀ (N. Vinokurov); Abkhazia Rep., env. Pitsunda, 13.VI 2010 , 1♀ ( MM) [ZIN] .

DIAGNOSIS. Chrysis lyda sp. n. belongs to the leachii species-group. It is related to C. aegeica Arens, 2016 , recently described from the Cyclades Islands

(Santorini and Ios). It can be separated from the latter through body coloration, with metascutellum blue contrasting with the rest of mesosoma ( Fig. 9D View Fig ) (vs. concolour in C. aegeica ), T1 and T2 posteriorly with a blue margin ( Fig. 9E View Fig ) (vs. concolour);

it is morphologically separated through slender body (vs. robust, compare pictures in

Arens 2016), with narrow pronotum (vs. larger and subrectangular with subparallel anterior sides); sculpture of scapal basin, with peculiar double oriented wrinkles

( Fig. 9A View Fig ) (vs. weakly wrinkled, almost polished): wrinkles orientation, on lower scapal basin, may vary in some specimens, being more or less horizontal or concave.

Male genitalia are similar to C. verhoeffi Linsenmaier, 1959 (known from Corfu and continental Greece) and C. ignescoa Linsenmaier, 1959 (Cypriot endemism). It can be separated from these two species by coloration (similar to C. leachii Shuckard,

1837 in the other two species). The body coloration is similar to C. ignigena Linsenmaier, 1959 (Cypriot endemism), but the latter has different male genitalia

(Linsenmaier 1959: Fig. 338). The fully metallic red pronotum, mesoscutum and mesoscutellum is also observed in C. cypruscola Linsenmaier, 1959 (Cypriot endemism), which is distinct for head, tegulae, propodeum and T1 medially blue,

and shape of male genitalia (Linsenmaier 1959: Fig. 339).

DESCRIPTION. Body length 4.5–6.0 mm. Fore wing length 2.8–4.0 mm.

Female. OOL = 1.5 MOD; POL = 1.8 MOD; MS = 1.5 MOD; relative length of P:

F1: F2: F3 = 1.0: 1.5: 0.8: 0.7.

Head. Vertex and frons with large (up to 0.8 MOD), irregular and contiguous punctures; in some specimens with areolate-reticulate punctures, even partially fused; TFC faint. Scapal basin finely microridged: in the holotype microridges have two orientations, arched downwards in the upper part and opposite directed in the lower part (in some specimens lower scapal basin may be medially polished or with subparallel microridges); anterior margin of clypeus medially slightly emarginated;

subantennal space less than 1 MOD; malar spaces convergent. Genal carina fully developed to mandible.

Mesosoma. Pronotal groove weak and broad, almost reaching 2/3 of pronotum length; punctuation on mesosoma irregular, with punctures of different size, mostly contiguous with narrow interspaces ( Fig. 9C View Fig ); propodeal teeth acute and divergent.

Episternal sulcus with deep, subrectangular to subsquare foveate punctures ( Fig. View Fig

9B), often metallic green in contrast with red coloration of mesopleuron.

view; C – mesosoma, dorsal view; D – mesosoma, detail; E – T3, dorsal view; F – metasoma,

dorso-lateral view. Scale bar = 0.5 mm.

Metasoma. Punctuation on T2 with small punctures ( Fig. 7E View Fig ), becoming larger and scattered (up to 1PD apart) laterally ( Fig. 9F View Fig ); pit-row with pits of variable size:

in the holotype and some paratypes pits are round, small, brown without metallic colour. Apical margin of T3 with a small median denticle, more or less protruding in paratypes.

Coloration. Coloration pattern: body metallic red ( Fig. 7E View Fig ); green to blue on metascutellum and propodeum medially (dorsal area of the metapectal-propodeal complex) ( Fig. 9D View Fig ). Minor variations between holotype and paratypes are observed:

head, posterior margin of pronotum, mesoscutellum, mesonotum and metanotal trough, tegulae legs, posterior margin of T1 and T2, apical margin of T3 after pitrow usually red or with golden-greenish reflections. Black spots on S2 large and medially fused, covering 4/5 of sternite, posteriorly parallel to sternite margin.

Sternites dark purple to blackish, in one paratypes purple-red. Scape, pedicel and F1

basally metallic red, rest of flagellum black. Wings hyaline, smoky in radial cell.

Vestiture. Body covered with brownish to whitish, short, erect setae (1.0 to 1.5

MOD), laterally 1.5 MOD. Legs with erect brownish to whitish setae (1.0 MOD),

longer on femora (up to 2 MOD).

Male. Propodeum entirely green to blue, including propodeal teeth, whereas in female only median part of propodeum is green to blue. Some male paratypes show small colour differences as in female. Genitalia as in Fig. 7F View Fig .

DISTRIBUTION. Russia (Krasnodar Territory, Stavropol Territory), Abkhazia

Republic.

ETYMOLOGY. The specific name lyda (feminine noun, nominative case) is named after Lydia Vinokurova (Mineralnye Vody, Russia).

REMARKS. Vinokurov (2011) identified this species as C. excursa Linsenmaier, 1959 , which is a Northern African species well distinct through the uniform coppery body coloration and the undulate apical margin of T3, a unique feature in this species-group.
