          Abstract

          ABSTRACT A list of all valid names of species of Neotropical electric fishes (Gymnotiformes) is presented herein. The list is arranged by family and genus and includes all available synonyms. The list is comprehensive through 2016 and includes 240 valid species distributed among 34 genera and five families, including one monotypic genus known only from the fossil record. The presented classification reflects recently published interpretations about the validity of the included names which, in general, are widely accepted. When the validity of a particular name is disputed in recent literature, we followed one of the published interpretations and provide relevant information on the alternate interpretation(s) in the remarks section of that name. Synonymies of some names need to be considered tentative, inasmuch as the types underlying those names are either absent or appear to be based on more than one taxon. First reviser actions (e.g., lectotype and neotype designations, resolution of simultaneous synonyms, etc.) are reported and include erroneous subsequent attempts at problem resolutions. Herein, we include one new first reviser action by selecting Gymnotus aequilabiatus Humboldt, 1805, as type species of Sternopygus because previous attempts to select a type did not follow the provisions of the Code of Zoological Nomenclature.

          RESUMO Uma lista de todas as espécies válidas de peixes elétricos neotropicais (Gymnotiformes) é apresentada. A lista é organizada por família e gênero, e inclui todos os sinônimos válidos. A lista encontra-se atualizada até 2016 e inclui 240 espécies válidas viventes distribuídas entre os 34 gêneros e cinco famílias, e um gênero monotípico conhecido apenas por registros fósseis. A presente classificação reflete as recentes interpretações publicadas sobre a validade dos nomes incluídos, nos quais, em geral, são amplamente aceitos. Quando a validade de um nome em particular é disputada na literatura recente, nós seguimos uma das interpretações publicadas, e fornecemos informações relevantes sobre a(s) interpretação(ões) na seção de comentários do nome em questão. Sinônimos de alguns nomes precisam ser considerados com cautela, tendo em vista que os tipos para estes nomes são ausentes, ou parecem ser baseados em mais de um táxon. As primeira ações de revisão (e.g., designação de lectótipos e neótipos, resolução na designação simultânea de sinônimos, etc.) são registradas e incluem os esforços errôneos subsequentes para a solução do problema. Aqui, nós incluímos uma primeira ação de revisão selecionando Gymnotus aequilabiatus Humboldt, 1805, como a espécie-tipo de Sternopygus, porque os esforços prévios para selecionar o tipo não seguiram as recomendações do Código de Nomenclatura Zoológica.

          Model-based total evidence phylogeny of Neotropical electric knifefishes (Teleostei, Gymnotiformes).

          This study provides the most comprehensive Model-Based Total Evidence (MBTE) phylogenetic analyses of the clade Gymnotiformes to date, reappraising relationships using a dataset comprised of six genes (5277bp) and 223 morphological characters, and an ingroup taxon sample including 120 of 212 valid species representing 34 of the 35 extant genera. Our MBTE analyses indicate the two main gymnotiform clades are Gymnotidae and Sternopygoidei, the latter comprised of Rhamphichthyoidea (Rhamphichthyidae+Hypopomidae) and Sinusoidea (Sternopygidae+Apteronotidae). Within Gymnotidae, Electrophorus and Gymnotus are sister taxa, and Gymnotus includes the following six clades: (i) G. pantherinus clade, (ii) G. coatesi clade, (iii) G. anguillaris clade, (iv) G. tigre clade, (v) G. cylindricus clade, and (vi) G. carapo clade. Within Rhamphichthyoidea, Steatogenae (Steatogenys+Hypopygus) is a member of Rhamphichthyidae, and Hypopomidae includes the following clades: (i) Akawaio, (ii) Hypopomus, (iii) Microsternarchini, and (iv) Brachyhypopomus. Within Sternopygidae, Sternopygus and Eigenmanninae are sister groups, Rhabdolichops is the sister to other Eigenmanninae, Archolaemus+Distocyclus is the sister to Eigenmannia, and Japigny is nested within Eigenmannia. Within Apteronotidae, Sternarchorhamphinae (Sternarchorhamphus+Orthosternarchus) is the sister to Apteronotinae, Adontosternarchus is the sister group to other Apteronotinae, Sternarchorhynchini (Sternarchorhynchus+Platyurosternarchus) is the sister to Navajini, and species assigned to Apteronotus are members of two separate clades: (i) A. sensu stricto in the Apteronotini, and (ii) the "A." bonapartii clade in the Navajini.
