Thermichthys (Bythitidae), replacement name for preoccupied Gerhardia Nielsen & Cohen, 2002 and a second specimen of Thermichthys hollisi from the Southeast Pacific

A replacement name, Thermichthys, is suggested for the preoccupied, monotypic fish genus, Gerhardia Nielsen & Cohen, 2002. A second specimen of Thermichthys hollisi (Cohen, Rosenblatt & Moser, 1990) caught at the hydrothermal vent site Hobbs is here described and compared to the holotype from the Galapagos Rift Zone about 4000 km northeast of Hobbs. The new specimen is a male but otherwise there is hardly any difference between the two specimens.Original Abstract: Un nouveau nom, Thermichthys, est propose pour remplacer celui, deja occupe, du genre monotypique Gerhardia Nielsen & Cohen 2002. Un deuxieme specimen de Thermichthys hollisi (Cohen, Rosenblatt & Moser, 1990), capture sur le site hydrothermal Hobbs, est decrit ici et compare a l'holotype provenant de la zone de la ride des Galapagos situee environ a 4000 km au nord-est de Hobbs. Le deuxieme specimen est un male, mais il est tres difficile de trouver une difference entre les deux specimens.
