A new sexually dimorphic species of the armoured catfish genus Neoplecostomus (Siluriformes: Loricariidae) from Neotropical Atlantic coastal drainages

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of the small‐sized armoured catfish genus Neoplecostomus is described from Neotropical Atlantic coastal drainages, in southeast Brazil. The new species can be readily diagnosed from all congeners by having the first plates of the ventral series reduced in size, rounded and ventrally displaced, resulting in a naked band between ...

We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.
