Gymnotichthys Fernández-Yépez, 1950

The unique known species of this genus, Gymnotichthys hildae Fernández-Yépez has a naked predorsal line as occurs in Gymnocorymbus and the overall body shape and coloration are similar to some Moenkhausia of the lepidura -group (Géry, 1977). If this species is related with some of these genera, it should be included in the Tetragonopterinae . Indeed, if the Moenkhausia lepidura - group of Géry (1977) is monophyletic and includes G. hildae , all its species should be transferred to Gymnotichthys , according to the hypothesis herein proposed. However, all these conjectures are speculative in the current state of knowledge and further studies are necessary to assess the relationships of this genus.
