Type species: Cavonus armatus Sharp, 1875 , by monotypy. Coelothorax Ancey, 1880: 212 ; Blackburn 1888: 287 (synonymy). Type species: Coelothorax oberthuri Ancey, 1880 , by monotypy. Neocavonus Blackburn, 1888: 225 ; Carne 1957: 127 (synonymy). Type species: Neocavonus niger Blackburn, 1888 , designated by Cassis & Weir (1992) . Comments. Blackburn (1888) included two species in Neocavonus , N . niger Blackburn, 1888 , and N . occidentalis Blackburn, 1888 , the latter albeit only with some hesitation, and did not designate either as the type species. He later ( Blackburn 1896 ) added Neocavonus bidens Blackburn, 1896 . Carne (1957) transferred N. occidentalis out of Neocavonus to Orthocavonus Carne, 1957 at the same time as he synonymised Neocavonus with Cavonus , retaining C. niger as the only species originally attributed to Neocavonus . This does not constitute a type fixation (Article 69.4, International Commission on Zoological Nomenclature 1999 ). However, the designation of N. niger as the type species by Cassis & Weir (1992) does fix it as the type species, although they incorrectly attributed this status to Blackburn (1888) .
