Diagnosis.

Holopyga tyrneri sp. nov. is characterised by metasoma with noticeably scattered punctures, with shallow punctures on terga and relatively dense punctures on S2; head and mesosoma deep blue, with pronotum and mesoscutum flame red; metasoma red flame to golden-red.

Description.

Male. Body length 6.0-6.9 mm (holotype 6.9 mm). Head. Brow and vertex with irregularly-sized punctures, with narrow, polished interspaces; punctures on face between scapal basin and eye larger; face shallowly hollowed; scapal basin transversally microridged, polished below brow, glabrous; genae with coarsely, irregular and confluent punctures; mandibles bidentate; ocellar triangle isosceles, with deep ocellar line connecting posterior ocelli. Relative length of P:F1:F2:F3 = 1.0:2.0:1.2:1.2; OOL = 2.2 × MOD; POL = 2.3 × MOD; MS = 0.5 × MOD. Mesosoma. Pronotum with deep, irregularly-sized punctures mixed with small dots on interspaces; posterior margin with small dots only; mesoscutum with shallow, large punctures (0.5 × up to 1.0 × MOD on basal half), with scattered dots anteriorly on narrow interspaces; punctures dense and subcontiguous basally; mesoscutellum with larger (1.0 × MOD), irregular and dense punctures with narrow, polished interspaces; notauli and parapsidal lines deep, as fine lines; with large antero- and postero-median area polished and with shallow small dots; mesopleuron with dense, large punctures, irregularly confluent along posterior margin; metascutellum with dense large punctures, as large as those on mesoscutellum, with narrower interspaces; propodeal posterior projections small, subparallel, pointing slightly outwards. Legs and wings unmodified compared with similar species. Metasoma. Metasomal terga with even and minute punctures, equally spaced dorsally, 2-3 PD apart (Fig. 17E ); with some denser, larger punctures on T1 antero-laterally; apical margin of T3 with narrow brownish rim; S2-S3 with dense punctures (Fig. 17F ). Colouration. Head and mesosoma deep blue, with pronotum and mesoscutum flame red; metasoma red flame to golden-red; scape green, pedicel and flagellum black; clypeus non-metallic brown; legs metallic green to blue with brownish tarsi; metasomal sterna black without metallic reflections; forewing hyaline, slightly darkened medially.

Female. Body length 6.0-7.0 mm. Similar to male in habitus and colour pattern and with dimorphic T3, acutely arcuate (Fig. 18E ). Flagellum I distinctly longer l/w = 3.5 (l/w 2.5 in male); posterior propodeal projections more divergent and acute; metasoma with more scattered, minute punctures.

Etymology.

The specific epithet Holopyga tyrneri (masculine noun in genitive) is dedicated to Pavel Tyrner ( Litvínov, Czech Republic), who collected and provided data from Mongolia and for his precious contribution to the knowledge of the European Chrysididae .

Comparative diagnosis.

Holopyga tyrneri sp. nov. is closely related to Holopyga similis Mocsáry, 1889 [= H. chrysonota sensu Linsenmaier (1959)] for habitus and same colour pattern in both sexes. It can be immediately separated by metasoma with noticeably scattered and shallow punctures (Fig. 18E ) compared with H. similis (Fig. 18D ) and by different genital capsule. The female also resembles Holopyga chrysonota ( Förster, 1853) [= H. ignicollis sensu Linsenmaier (1959)] by colour pattern; however, it can be separated by metasoma with scattered, shallow punctures and by denser punctures on S2 (vs. scattered with only few dots in H. chrysonota ). The male of Holopyga chrysonota is differently coloured, with mesosoma green, pronotum and mesoscutum usually lighter.

Distribution.

Mongolia (Arkhangai, Bulgan, Dornod, Sukhbaatar, Zavkhan).
