Chani-Posse, Mariana, Newton, Alfred F., Hansen, Aslak Kappel & Solodovnikov, Alexey, 2018, Checklist and taxonomic changes for Central and South American Philonthina (Coleoptera: Staphylinidae), Zootaxa 4449 (1), pp. 1-95: 30-31

Bisnius Stephens 1829  Edit

Bisnius Stephens 1829a: 23  Edit , attributed to Leach. Type species: Staphylinus cephalotes Gravenhorst,1802  Edit , by virtual monotypy.

Notes: There are 84 valid species of Bisnius  Edit distributed worldwide (Newton unpublished database).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  Edit as a non-monophyletic genus within a major clade that includes representatives of both Gabrius Stephens  Edit and the so-called Neotropical lineage. After Stephens (1829b, 1832) and Curtis (1829), most authors considered Bisnius  Edit as a synonym or subgenus of Philonthus  Edit (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.
