Abstract

BIRINDELLI, José L. O.  and  ZUANON, Jansen. Systematics of the Jaguar catfish genus Liosomadoras Fowler, 1940 (Auchenipteridae: Siluriformes). Neotrop. ichthyol. [online]. 2012, vol.10, n.1, pp.1-11. ISSN 1679-6225.  https://doi.org/10.1590/S1679-62252012000100001.

Liosomadoras Fowler, 1940 includes two nominal species: L. oncinus, described from the rio Negro in Brazil, and L. morrowi described from the Peruvian Amazon. Both species are known from only few specimens deposited in fish collections, and information on these fishes is scarce. In order to rectify this situation, diagnoses of the genus and its species and an osteological description of L. oncinus are presented based on recently collected specimens. In addition, the taxonomy of the species of Liosomadoras is reviewed, and L. morrowi is confirmed as distinct from L. oncinus, and also distributed in the Brazilian Amazon. Liosomadoras is hypothesized as a relatively basal genus within Auchenipterinae, sister to all other species of the group, except Asterophysus batrachus and Tocantinsia piresi.

Keywords : Auchenipterinae; Doradoidea; Phylogeny; Taxonomy.
