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.
