C o m m e n t: Leptusa knappeorum was originally described from the Galicica range "unmittelbar südlich des Ochrid-Sees in Nordwest-Macedonien" ( SCHEERPELTZ 1964 ). The genitalia of this species are highly similar to those of L. peristerica , whose original description is based on four type specimens from "Perister, Perka, Macedonia " ( PACE 1989 ) and which was subsequently reported also from several localities in northern Greece ( ASSING 2006 ; ASSING & WUNDERLE 2001; ZERCHE 2002 ). It does not seem unlikely that these differences will eventually have to be attributed to intra- rather than interspecific variation. The specimens listed above significantly expand the known range of L. knappeorum further to the north.
