Metasoma ( Fig. 53 ). Petiolate and polished. Terga 1–3 smooth without fine punctures, anterior half of following terga coriaceous.

Distribution. Italy, Korea (Seoul, GG, GW, CN).

Remarks. Since the original description of this species by Kieffer (1906) from Italy, no more information was added. Kieffer (1906) considered as Rhabdepyris Kieffer because he interpretated the scutellar pits are separated from each other by a low median trabeculate, as a wide groove. This is one pattern of scutellar pit variation of Epyris , and because of that we transfer Rhabdepyris fuscipes to Epyris . This species are recorded for the first time from Korea in spite that distribution has a large gap between Italy and Korea. It is one of the most abundant species of Epyris in Korea with more than 130 identified specimens, this gap can be explained by absence of collection data.

The male and female mophologically differ from each other by ratio of head, by ratio of each antennal segment, by status of metacarpus. However, these characters are common sexual dimorphism in genus Epyris as in the case of E. yamatonis Terayama. We regard male and female as an opposite sexes of one species because they have common such characters as mandible with five teeth, upper four teeth minute and lowest tooth long and sharpended, clypeus well developed apically with obtuse angle, same sculptures and carinae on propodeal disc. In comparison with the holotype, the specimens from Korea have texture stronger, wings more colorful.
