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 ).
