SPECIMENS EXAMINED. Holotype – ♀, Turkmenistan: env. Ashgabat,

3.VIII 1931 [ ZIN] .

DIAGNOSIS. Chrysis hyalinopyga sp. n. belongs to the C. rufitarsis species group. It can be easily separated from all other species by shape of the last metasomal tergum, apically bordered with a broad hyaline rim. The only known species, within this group, with apical hyaline rim is C. parthorum Semenov, 1967, described from

Iran. Chrysis hyalinopyga sp. n. can be separated from the latter for: apical margin of T3 medially straight (vs. noticeably bisinuate in C. parthorum); lateral emargination of T3, deeper and starting closer to basal margin than in C. parthorum;

body colouration light green to golden (vs. distinctly darker and bicoulored, with red metasoma); squarish black spots on S2 (vs. rounded in C. parthorum).

DESCRIPTION. Body length 6.1 mm. Forewing length 4.0 mm. Female. OOL

= 1.6 MOD; POL = 2.0 MOD; MS = 1.1 MOD; relative length of P:F1:F2:F3 =

1.0:1.2:0.9:0.6.

Head. In full face view, length 1.4 mm, width 1.7 mm. Apex of clypeus arched,

medially raised; TFC hardly raised and vaguely M-shaped, with two rami almost enclosing midocellus; scapal basin almost flat, overall densely covered with minute punctures, and with silvery, appressed setae; frons and vertex with irregular, small to medium-sized, contiguous to confluent punctures. Ocelli area distinctly raised on vertex. Malar space 1.0 MOD, shorter than F1. Mandibles with subapical tooth.

Subantennal distance about 1.0 MOD. Genal carina fully developed to mandibular joint; malar spaces finely punctate.

Mesosoma. Length 2.3 mm; width (PPW) 1.6 mm. Pronotum anteromedially depressed, yet without a distinct groove; punctation irregular, with uneven punctures and tiny punctures on interstices. Mesoscutum basally with larger, closer punctures among notauli; lateral lobes with sparser punctures; notauli deep, formed by elongate subrectangular foveae. Mesoscutellum with even punctures, 1 PD apart, and polished interstices; anterolateral corners over axillary trough large and digitate. Metanotum very narrow, about one third of mesoscutellar length, with reticulate punctures. Mesopleuron with double punctation; episternal sulcus deep and complete. Propodeal teeth broad, divergent.

Metasoma. Length 2.7 mm. Punctation on T1 with small, even, medially scattered punctures, with small punctures on interstices; T2 with geminate punctures and shining interstices; anteromedially with larger, posteriorly with smaller and sparser punctures; median carina present on T2 and T3; T3 with punctation similar to the posterior half of T2; pits of the pit row small, round, yet very deep; post pit row area about 1.0 MOD; apical margin of T3 with lateral triangular angles, medially straight;

apical margin with broad hyaline rim. Black spots on S2 squarish, medially almost fused, covering about half sternum length.

habitus, lateral view; 25 – head, frontal view; 26 – metasoma, postero-lateral view. Scale bar

= 1.0 mm.

Coloration. Head and mesosoma green; propodeum, notauli and axillary trough bluish; metasoma golden-greenish. Mandibles with metallic green reflections at base,

medially testaceous, apically darker. Scape, pedicel and F1 greenish, the remaining flagellomeres light brown. Legs metallic red, yellowish on joints, tarsi light yellowish,

slightly darkened at apex. Tegulae metallic green. Wings hyaline with light brown nervures.

Vestiture. Body with short (1.0 MOD), erect, whitish setae.

Female. Unknown.

DISTRIBUTION. Turkmenistan.

ETYMOLOGY. The specific epithet hyalinopyga (adjective) refers to the unu-

sually broad hyaline edge of the third (anal) metasomal segment.
