Sousa, J. de S., Sarmento-Soares, L.M., Canto, A.L.C. & Ribeiro, F.R.V. 2020. Description of a new species of Tatia from rio Tocantins drainage, central Brazil, with notes on Tatia simplex Mees, 1974 (Siluriformes, Auchenipteridae). Neotropical Ichthyology, Volume 18, Number 1. Epub April 17, 2020.
ABSTRACT:
Tatia comprises twenty-five valid species, distributed in the main inland watersheds of South America, including the Orinoco, Essequibo, and coastal rivers of Suriname, Amazon, upper rio Paraná and São Francisco basins. A new species is described from tributaries of upper rio Manuel Alves on uplands of Serra Geral do Tocantins plateau, Tocantins State, Brazil. It is promptly distinguished from all congeners, except Tatia britskii, due to absence of an adipose fin. It differs from T. britskii by the longer caudal peduncle length (24.1–30.5% SL, mean 25.3 vs. 20.0–22.7, mean 20.9); caudal peduncle depth (10.9–16.8 SL, mean 14.1 vs. 9.4–10.5, mean 9., and anterior cranial border with mesethmoid width equals its length (vs. width approximately three times its length in T. britskii). Additionally, information regarding the poorly known species Tatia simplex originally described from rio das Mortes, is provided.
The new species is named Tatia akroa.
Note: There is a goof to be corrected. On the third page at the beginning of the description of the new species the name "Astyanax varii" is used. OOOPS! The senior author has been contacted.

That is a big oops. Glad you (or someone) contacted the author.
