Tselikh, Ekaterina V., Rasplus, Jean-Yves, Lee, Jaehyeon & Ku, Deok-Seo, 2025, Krasava, a new genus of Pteromalidae (Hymenoptera, Chalcidoidea) from the Palaearctic region, Zootaxa 5715 (1), pp. 489-493 : 490

Genus Krasava Tselikh, Rasplus & Lee , gen. nov.

( Figs 1–7 )

Type species. Krasava sergeyi Tselikh , sp. nov., by present designation.

Description. Female. Body black with a dark metallic blue lustre ( Figs 1, 7 ); fore wing with light brownish tint ( Fig. 3 ).

Head in dorsal view, 2.00–2.08× as broad as long, scrobes absent ( Fig. 4 ); gena and occiput without carina. Clypeus broad and with neighbouring lateral parts convex, tentorial pits indistinct ( Fig. 2 ). Antennal formula 11264, with antennae inserted below level of lower edges of eyes ( Fig. 2 ), both anelli transverse, clava symmetrical with large micropilosity area in C1–C4 ( Fig. 5 ). Mandibular formula 3:3.

Mesosoma moderately arched dorsally. Pronotum almost as wide as mesoscutum, collar margin without carina ( Fig. 4 ). Notauli incomplete ( Fig. 7 ); prepectus shorter than tegula, upper mesepimeron alutaceous. Scutellum convex, with indistinct frenal area and frenal groove. Propodeum with concave median area, nucha short, spiracles positioned closer to metanotum ( Fig. 6 ). Petiole transverse. Fore wing narrow, with speculum; basal cell partly pilose, veins not thickened ( Fig. 3 ). Hind coxa bare dorsally; hind tibia with two spurs.

Metasoma lanceolate, longer than mesosoma and head combined ( Fig. 1 ), cerci with setae of subequal length, ovipositor not strongly exserted.

Male unknown.

Etymology. The generic name is the feminine noun “krasava ”, which means “handsome” in Russian.

Distribution. Eastern Palaearctic.

Comments. Krasava is similar to the cosmopolitan genus Psilocera Walker, 1833 ( Bouček, 1988; Bouček, Rasplus, 1991; Sureshan, Narendran, 2004; Xiau, Huang, 2019; UCD Community 2025) in several features including the large antennal clava with a wide micropilosity area ( Fig. 5 ); broad head, in dorsal view ( Fig. 4 ); head and mesosoma black ( Figs 1, 7 ); notauli incomplete ( Fig. 7 ); propodeum with spiracles positioned closer to metanotum ( Fig. 6 ); petiole transverse ( Figs 6, 7 ). However, Krasava gen. nov., can be distinguished by the clypeus with convex neighbouring lateral parts ( Fig. 2 ) vs clypeus without convex neighbouring lateral parts; lower margin of clypeus weakly emarginate ( Fig. 2 ) vs lower margin of clypeus with two teeth; antenna inserted below ocular line ( Fig. 2 ) vs antenna inserted above ocular line; propodeum with concave median area and without subglobose nucha and costula ( Fig. 6 ) vs propodeum without concave median area and with subglobose nucha and costula; fore wing narrow ( Fig. 3 ) vs fore wing not narrow.

Krasava also resembles the Palaearctic genera Monoksa Bouček, 1991 and Rohatina Boucek, 1954 in having a clypeus with convex neighbouring lateral parts ( Fig. 2 ); notauli incomplete ( Fig. 7 ); propodeum with spiracles positioned closer to metanotum ( Fig. 6 ); petiole transverse ( Figs 6, 7 ). However, the new genus clearly differs in the concave median area of propodeum ( Fig. 6 ) vs propodeum without concave median area; clava with a large micropilosity area on C1–C4 ( Fig. 5 ) vs micropilosity area never present on C1; antenna inserted below ocular line ( Fig. 2 ) vs antenna inserted above ocular line; fore wing narrow and slightly infuscate ( Fig. 3 ) vs fore wing not narrow and hyaline.
