Type species. Eopompilus orientalis Gussakovskij, 1932 = Sialus (!) internalis Matsumura, 1911, by original designation.
Diagnosis. Females. Females are easily separated from all other genera of tribe Priocnemini by having inner side of metatibia with smooth furrow along upper margin of brush, S2 with weak transverse furrow, and face along inner orbit always with yellow or ivory strip. Other characters of importance are: first flagellomere 5.0–6.3 times its width; propodeum matt and smooth, sometimes with dense soft punctures; claws with additional small tooth; body black or brown with few or abundant yellow spots on: head, mesosoma, metasoma and legs, face along inner orbit always with yellow spots; antenna from black with yellow-orange ventral side to almost yellow-brown (Figs 1, 3, 7, 8).
Males. Males are easily separated from all other genera of tribe Priocnemini by having posterior margin of S6 with row of dense short equal length bristles (Fig. 17), and flagellomeres 2–11 serrate beneath (Fig. 2). Other characters of importance are: first flagellomere 2.3–4.2 times its width; propodeum smooth or with dense punctures; tarsal claws usually without additional tooth, but sometimes bifid, with additional inner small tooth; body black or dark brown with few or abundant yellow (yellow-orange) spots on: head, mesosoma, metasoma and legs (Figs 2, 4, 5, 6).

(China: Yunnan).
Distribution. Palaearctic: Russia (the South of the Far East), China (Inner Mongolia, Heilongjiang, Ningxia, Hebei, Henan), South Korea, Japan (from Hokkaido in the North to Yakushima in the South). Oriental Region: China (Yunnan, Taiwan).
Biology. Spiders (Araneae) from the genera Achaearanea Strand, Theridion Walckenaer (Theridiidae), Leucauge White (Tetragnathidae) (Nambu & Shimizu 1994, Lelej 1995, Loktionov & Lelej 2014), and Araneus Clerck (Araneidae) have been recorded as hosts (see below) (Fig. 43).
