Hutchinson, Paul M. & Allsopp, Peter G., 2020, Cavonus Sharp, 1875 (Coleoptera: Scarabaeidae: Dynastinae: Pentodontini Pseudoryctina) in Western Australia with description of a new species and the female of Cavonus sculpturatus Blackburn, 1888, Zootaxa 4852 (4), pp. 449-460 : 450

Cavonus Sharp, 1875

Cavonus Sharp, 1875: 43 . 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).
