Belonuchus Nordmann 1837

Belonuchus Nordmann 1837: 129 . Type species: Staphylinus haemorrhoidalis Fabricius, 1801, by monotypy.

= Musicoderus Sharp 1885: 455 . Type species: Musicoderus cephalotes Sharp 1885, des. by Lucas 1920: 425. Notes: as subgenus of Belonuchus (Bernhauer 1916c: 266); as synonym of Belonuchus (Blackwelder 1943: 421) .

Notes: There are 165 valid species of Belonuchus distributed in CASA. A recent study (Chani-Posse et al. 2018) shows Belonuchus as a genus of Neotropical origin and generic limits so far undefined. The current concept of the genus is that of Smetana (1995), Chani-Posse (2014a) and Chani-Posse et al. (2018) but most of its Neotropical endemic species were never revised after being described and they do not fit into this concept. Species that may belong to the so called ‘ Belonuchus haemorrhoidalis clade’ (Chani-Posse et al. 2018) are here denoted with an asterisk *.
