Abstract

In order to clarify the identity ofParacacoxenus kaszabiOkada, 1973, a species described from Mongolia, the morphological structures of one male paratype, collected at 1,750 m altitude, were analyzed and redescribed. In addition, one of the male specimens, previously referred to in literature as ‘sp. aff.kaszabi’, is restudied and described asParacacoxenus macaisp. nov.(type locality: Schmelz, Parco Nazionale dello Stelvio, Province of Bolzano, Region of Trentino-Alto Adige, Italy). The former species seems to be distributed in central and eastern Asia while the latter is supposed to have an exclusively European distribution. The midtibial preapical seta of maleParacacoxenus argyreator(Frey, 1932), which is unusually long, is illustrated by photomicrographs. A key to the European species ofParacacoxenusHardy, 1960 is presented.
