New Combination of Pararrhynchium paradoxum koreanum (Hymenoptera: Vespidae: Eumeninae)

Abstract

An eumenid subspecies Pararrhynchium paradoxum koreanum Giordani Soika, 1986 is newly combined to the genus Pseudepipona de Saussure, 1856. Although tegula of this subspecies is similar to one of Allodynerus, shape of scutellar crest and related structures in both sexes and peculiar shape of mandible in male are critically justifiable for the genus Pseudepipona. This form is a discrete species in the genus, thus named as Pseudepipona koreanum (Giordani Soika, 1986) n. comb. The original description of this species was based on the sole male specimen and hardly diagnostic, just providing coloration compared with the nominotypical subspecies of P. paradoxum. A redescription of males and description of the hitherto unknown female are provided.
