Material examined.

Holotype, ♂, CHINA, Xinjiang, Akesu Prefecture, Baicheng County, Jinhui Industrial area , Ruifeng , 41.741°N, 81.643°E, 30.VII.2019, Lingzhi Zhao (CNU) ; Paratype, 1♂, the same as holotype (CNU).

Description.

Male: body length 8.0-8.5 mm (Fig. 1 ), fore wing length 7.0-8.0 mm. Body mostly ferruginous (Fig. 1 ), only with the following parts black: inner margin and apex of mandible, two oblique narrow stripes on frons, vertex, A8-A13 (A7 ferruginous with black) (Fig. 2 ), mesoscutum, anterior margin of scutellum, ventral side of mesosoma, posterior face of propodeum medially, a transverse spot at the base of T2 and metasomal segments 4-7 (Figs 6-7 ); apex of fore wing dark.

Head. In front view head (Fig. 4 ) slightly wider than long, its side rounded; clypeus (Fig. 4 ) slightly wider than long (1.02 ×), with sparse punctures, interspaces polished, and apically with deep semi-circular emargination and width of emargination 1.3 × depth; inter-antennal longitudinal carina present; frons with shallow and moderate punctures; punctures on vertex and gena denser and deeper than those of frons; A13 hooked (Figs 2-3 ); occipital carina complete.

Mesosoma. In dorsal view, mesosoma about 1.4 × as long as wide (Fig. 5 ); pronotal carina complete, without tooth-shaped protrusion and with protruding corner at shoulder, pronotum wholly with dense and reticulate punctures; mesoscutum with one medial prescutal furrow and two postscutal furrows, with irregular punctures, interspaces between punctures polished, punctures denser at base; scutellum with moderate punctures and a medial longitudinal furrow; punctures on mesopleuron similar to pronotum; metanotum with dense and coarse punctures, interspaces between punctures slightly denticulate and protruding above scutellum (Fig. 5 ); horizontal carina between dorsal and posterior surfaces of propodeum complete and strong (Fig. 5 ), dorsal surface coarsely punctate and honeycomb-like, lateral carina tooth-like between dorsal and lateral surfaces, lateral surface with thin transverse striae.

Metasoma. T1 (Fig. 7 ) 1.45 × as wide as long in dorsal view, densely and coarsely punctate, medially with slight depression, basally without lateral carina; T2 (Fig. 7 ) densely punctate, punctures slightly sparser and smaller than those of T1, and those at apex obviously bigger and denser; S2 mostly with sparse punctures except apex; apexes of S2-S3 with moderate punctures; apex of T3 with dense punctures; other visible parts of metasoma 4-6 densely with minute punctures.

Female. Unknown.

Distribution.

China (Xinjiang).

Remarks.

This species resembles P. (P.) przewalskyi (Morawitz, 1885) with similar coloration (Figs 1 , 54 ) and clypeus (Figs 4 , 58 ). It can be distinguished from the related species and other members of the genus by the following character combination: pronotal carina medially without tooth-shaped protrusion (Figs 3 , 5 ), and T2 with dense and coarse punctures (Fig. 7 ).

Etymology.

The specific name Pseudepipona punctulata is derived from Latin word: punctulate, referring to T2 with dense and coarse punctures.
