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 Notes: There are 84 valid species of Bisnius distributed worldwide (Newton unpublished database).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] Staphylinus cephalotes Gravenhorst 1802: 22. Type locality: Brunsuigae [Brunswick, Germany].
