The monotypic genus Acanopsilus (Hymenoptera: Diapriidae), is hitherto known only from Europe, where it is widely distributed.
The genus is here recorded for the first time from South Korea and China, which constitutes the first formal record of the species from the entire Eastern Palaearctic region. A detailed redescription and photographs of Acanopsilus heterocerus (Haliday, 1857) are provided. Also, Acanopsilus brevinervis Kieffer, 1909 is proposed as junior synonym of Anommatium ashmeadi Mayr, 1856 (syn. nov.).

Acanopsilus, a monotypic genus of tribe Pantolytini (Diapriidae: Belytinae) was established (
As a result of the present study, the known range of A. heterocerus is extended from Europe (Western Palaearctic) to South Korea and China (Eastern Palaearctic). A redescription of the species, along with figures of taxonomically important morphological features are provided.
The terminology used in the present study follows
The following abbreviations are used throughout the text: POL, distance between the inner edges of the two lateral ocelli; OOL, distance from the outer edge of a lateral ocellus to the compound eye; MT, Malaise Trap; YPT, Yellow Pan Trap.

Female (Fig.
Mesosoma. Mesosoma much longer than width (15: 9); cervix with two large pits and bare in dorsal view; pronotal shoulders angled; epomia absent; mesoscutum convex and covered with long setae; notauli complete; humeral sulcus distinct; scutellum smooth, covered with long sparse setae and convex; anterior scutellar pit large and deep, transverse (5: 4), longer than remaining scutellar disc; posterior scutellar pits absent; mesosoma in lateral view clearly longer than high (25: 16); lateral part of pronotum smooth, bare and shiny; upper part of mesopleuron smooth, bare and shiny with deep sulcus under tegula, without sternaulus; lower part of mesopleuron smooth and covered with sparse setae; median keel of dorsellum prominent, tubercle-shaped; propodeum transverse; posterior margin of propodeum slightly emarginated; posterior transverse propodeal keel distinctly raised; median propodeal keel raised into ridge.
Wing. Fore wing with costal, subcostal, marginal and stigmal veins tubular; basal, cubital and medial veins pigmented; stigmal vein short, nearly perpendicular to the marginal vein, as long as post-marginal vein and half of marginal vein.
Metasoma. Petiole cylindrical in dorsal view smooth, bare, shiny, with irregular longitudinal keels, with long setae laterally and dense cushion of long setae ventrally; base of T2 with several costae, not angled in lateral view; following tergites with micropunctures medially and few long setae laterally; all sternites with sparse short setae.
Color. Head black; mesosoma and metasoma dark brown to blackish brown; antenna brown, except A11–A14 dark brown; legs, tegula yellowish brown; palps yellow.
Measurements. Head length 0.43 mm, width 0.47 mm; mesosoma length 0.80 mm, width 0.52 mm; metasoma length 1.45 mm; fore wing length 2.05 mm; total body length 2.68 mm.
Male (Fig.
South Korea (new record), China (new record), widely distributed in Europe.

The genus Acanopsilus was established by Kieffer (1908) based on the description of a single species. Subsequently he (
