Jupiaba, ZANATA, 1997

JUPIABA ZANATA, 1997 View in CoL

Type species: Jupiaba poranga Zanata, 1997 .

New combinations: Jupiaba ajuricaba ( Marinho & Lima, 2009) comb. nov., Jupiaba anterior ( Eigenmann, 1908) comb. nov.

Diagnosis: The new composition herein proposed for a monophyletic genus Jupiaba is diagnosed from the remaining Stethaprioninae by the following combination of characters: rhinosphenoid present and expanded dorsally between the olfactory nerves, circuli present on posterior field of scales, the base of the inner premaxillary teeth approximately as wide as their distal portion, absence of bony hooks in mature males, and by the presence of two series of teeth in the premaxilla, a complete lateral line and a naked caudal fin.

Synapomorphies: The clade of Jupiaba , including its type species, is supported by 12 molecular and two morphological synapomorphies: abrupt decrease of dentary teeth (207:1) and presence of 25 or more gill filaments attached to leading edge of first ceratobranchial (304:1).

Jupiaba View in CoL was herein obtained in two separate clades, with three species, including the type species, Jupiaba poranga View in CoL , in this clade, and three species in the Stethaprionini [‘ Jupiaba ’ acanthogaster ( Eigenmann, 1911) View in CoL , ‘ Jupiaba ’ mucronata ( Eigenmann, 1909) View in CoL and ‘ Jupiaba ’ scologaster (Weitzman & Vari, 1986) View in CoL ]. Because several species of Jupiaba View in CoL were not analysed, the complete composition of the genus is still unknown.
