Atopodontus adriaensi, a new genus and species of African suckermouth catfish from the Ogooué and Nyanga River systems of Gabon (Siluriformes: Mochokidae)

Abstract

Atopodontus adriaensi, a new genus and species of suckermouthed mochokid catfish, is described from the Ogooué and Nyanga basins of Gabon. It superficially resembles Atopochilus savorgnani, and is known to co-occur with this species at several localities. This new taxon can be distinguished from all other chiloglanidin species by a combination of features including robust mandibular teeth arranged in transverse rows that are approximately 66% of the width of the paired premaxillary tooth patches, and the presence of an anteriorly directed cavity located dorsal to the lower lip and ventral to the oral cavity.New taxa: Atopodontus Friel and Vigliotta, Atopodontus adriaensi Friel and Vigliotta
