Peromyia impexa (SKUSE, 1888) and related species

Most PeromyiaPeromyia specimens from Tasmania belong to the species complex around Peromyia impexa [= Peromyia palustris]]. This species complex is quite common in the Holarctic Region and also present in New Zealand ( JASCHHOF 2001b, JASCHHOF & JASCHHOF 2004, 2009). Compound microscope study of male anatomy suggests there are eight or more sibling species of this complex alone in Japan, but based on just that method I am unable to ascertain the definite interspecific boundaries.The situation with impexa -like peromyias in Tasmania is comparable, so I refrained here from a detailed study. Among the 120 or so specimens at my disposal are several that do not differ from typical Peromyia impexaimpexa from Europe (cf. the species redescription by JASCHHOF 1998).
