Comment: Drusilla puncticollis, whose descriptions is based on two syntypesfrom “Kamtschatka” ( MOTSCHULSKY 1845), was previously treated as a subspecies of D. canaliculata( SMETANA 2004). According to MOTSCHULSKY (1845), who already expressed doubts regarding the status of this taxon (“Je propose cette espèce avec doute”), D. puncticollisis distinguished from D. canaliculataby larger body size, darker coloration, and a more deeply impressed pronotum. Examined material from the eastern East Palaearctic region indeed tends to be darker and of slightly larger size than material from West Europe; for previous records see ASSING(2005a, b, 2006b, 2008a, 2009, 2010). However, similar character conditions have been observed also in specimens from some regions in Middle Asia and the West Palaearctic region (particularly Iran), suggesting that these differences should be interpreted as intraspecific, possibly clinal variation. Moreover, the presence of a distinct subspecies in Kamchatka appears most unlikely. Hence the synonymy proposed above. The previously known trans-Palaearctic distribution of D. canaliculataextended from West Europe to the Russian Far East ( SMETANA 2004). The above specimens from Hokkaidorepresent the first records from Japan.
