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 .
