description: Bisnius Stephens 1829
Bisnius Stephens 1829a: 23, attributed to Leach. Type species: Staphylinus cephalotes Gravenhorst,1802, by virtual monotypy.
Notes: There are 84 valid species of Bisnius distributed worldwide (Newton unpublished database). However, only three of them had been recorded from the Neotropical region and none of those was endemic to this area prior to the present study. A recent study (Chani-Posse et al. 2018) reveals Bisnius as a non-monophyletic genus within a major clade that includes representatives of both Gabrius Stephens and the so-called Neotropical lineage. After Stephens (1829b, 1832) and Curtis (1829), most authors considered Bisnius as a synonym or subgenus of Philonthus (see Herman 2001d: 2537) until Smetana (1995: 513) recognized it as a valid genus and revised its species from America North of Mexico. We owe its current concept to this author.
Bisnius cephalotes (Gravenhorst 1802) [adventive in CASA]

Bisnius instabilis (Horn 1884)
Philonthus instabilis Horn 1884: 218. Type locality: Colorado [no specific locality]. Type depository: MCZ LT ♂, 2 PLT. Distribution: Canada, USA, Mexico. Notes: comb. nov. ex Philonthus, lectotype designation, no Mexican records (Smetana 1995: 599); distribution within (and including) Mexico (Navarrete-Heredia et al. 2002).
Bisnius sordidus (Gravenhorst 1802) [adventive in CASA]
Staphylinus sordidus Gravenhorst 1802: 176 (senior primary homonym of Staphylinus sordidus Marsham 1802: 514). Type locality: Brunsuigae [Germany]. Type depository: ZMHB LT ♂, 8 PLT.

= Staphylinus chilensis Solier 1849: 315. Type locality: San Carlos, Coquimbo & Longotomo [Chile]. Type depository: MNHN? #? ST. Distribution: Chile. Note: as synonym of S. sordidus (Fauvel 1866: 344).
= Staphylinus chloropterus Solier 1849: 319 (preoccupied, junior primary homonym of Staphylinus chloropterus Panzer 1796: pl.20). Type locality: no specificic locality “en los lugares húmedos”. Type depository: MNHN? #?ST. Distribution: Chile. Note: as synonym of S. sordidus (Fauvel 1866: 344).
= Philonthus bruchi Bruch 1915: 501, attributed to Bernhauer in litteris; nomen nudum. Locality: Buenos Aires. Note: One specimen in MACN hand-labeled " Philonthus Bruchi Brh. tipo" by Bruch and " Bruchi n. sp." by Bernhauer was identified as Bisnius sordidus by MCP in 2010; an additional specimen in FMNH was identified as Bisnius cephalotes by MCP in 2003 (Bachmann et al. 2017: 44).
