Drusilla (Drusilla) canaliculata (FABRICIUS, 1787)

Myrmedonia polyporina GISTEL, 1857: 17 ; syn. nov.

Comment: HLAVÁČ et al. (2011) list Drusilla polyporina ( GISTEL, 1857) as a nomen dubium. The original description, which is based on an unspecified number of syntypes from “Styriae”, is practically devoid of relevant information. All that is specified is the coloration (“nigerrima; antennis thorace elytris et pedibus fuscis”), the size, and that it is close to D. canaliculata . The type material is presumably lost (ASSING 2008). However, it can be inferred that the type material of D. polyporina is conspecific with D. canaliculata , the only representative of the genus distributed in what used to be “Styria” ( ASSING 2005b). In order to dispose of the doubtful D. polyporina , it is placed in synonymy with the senior synonym D. canaliculata .
