Parepidosis Kieffer, 1913 View in CoL

This genus contained previously 11 species in the Palearctic and two species each in the Nearctic and Oriental regions ( Jaschhof & Jaschhof 2013; Gagné & Jaschhof 2017). Validation of the generic affiliation of the extra-Palearctic species is pending. Of the Palearctic species, four are poorly known and in need of redescription ( P. mamaevi Neacşu , P. militaris Mamaev , P. ulmicorticis Mamaev , P. ventralis Yukawa ), whereas the taxonomy of the remaining seven was recently revised on the basis of mostly Swedish material ( Jaschhof & Jaschhof 2013: 198 ff.). A new Parepidosis described here from Swedish Lapland shows that novelties hide even in regions that were intensively surveyed for Porricondylini in the past.

Parepidosis , again a genus of group Aa, is characterized by male genitalic features, as follows (see Jaschhof & Jaschhof 2013: 199). The parameres are fused posteriorly to form an inverted U or V with a pair of small, knob-like processes at the apex. The aedeagal apodeme is a long, moderately sclerotized rod whose apex – itself indistinguishably merged with the membranous aedeagal bulge – is modified in different, species-specific ways. While in many species the parameres are bent dorsad, the aedeagal apodeme is inclined markedly ventrad―a character that helps to identify a male Parepidosis even by means of a dissecting microscope. The gonostylus is, typically, a stout body of complex three-dimensional structure with a pectinate claw either apically or medially. Gonocoxal processes are absent.
