Revision in part of the genus Nebrioporus Régimbart, 1906, with emphasis on the N. laeviventris-group (Coleoptera: Dytiscidae) Author Toledo, Mario text Zootaxa 2009 2009-03-16 2040 1 111 journal article 1175­5334 Nebrioporus nipponicus ( Takizawa, 1933 ) Deronectes ( Potamodytes ) nipponicus Takizawa (1933: 117) (orig. descr.). Potamonectes nipponicus (Takizawa) ; Nakane (1990: 64) . Nebrioporus nipponicus (Takizawa) ; Mori & Kitayama (1993: 86) . Nebrioporus (s.str.) nipponicus (Takizawa) ; Nilsson (2001: 172 ; 2003: 66 ); Ribera (2004: 484, 486). Type locality. Japan > Honshu > Tamagawa and Tokyo . Type material. A series of syntypes in EIHU. The status of this taxon must be revised, comparing the type of N. hostilis and Japanese material formally named under N . hostilis . It seems probable (Liang-Jong Wang, personal communication, 2007) that it is a valid species and not a synonym of N . hostilis ; this is also in accord with Nakane (1990) and Mori & Kitayama (1993) .
