Peter R. Møller, Werner Schwarzhans, Thomas M. Iliffe & Jørgen G. Nielsen, 2006, Revision of the Bahamian cave-fishes of the genus Lucifuga (Ophidiiformes, Bythitidae), with description of a new species from islands on the Little Bahama Bank., Zootaxa 1223, pp. 23-46 : 26-27

Lucifuga

Lucifuga Poey, 1858 : 95 (type species: Lucifuga subterraneus Poey, 1858 by subsequent designation of Jordan and Evermann (1896), type locality: Caves of San Antonio, South Cuba .

Stygicola Gill, 1863 : 252 (type species: Lucifuga dentatus (Poey, 1858) by original designation, type locality: Cave of Cajio , Cuba ).

Remarks. Poey (1858) described Lucifuga subterraneus and Lucifuga dentata after the generic description in the same volume, without type species designation. The designation of a type species was done subsequently by Jordan and Evermann (1896) as stated in Cohen and McCosker (1998) and Nielsen et al. (1999), and not by monotopy as stated in Eschmeyer (1998) and Nielsen (2003).
