New Parotocinclus

[Silurus]

Roxo, FF, BF Melo, GSC Silva & C Oliveira, 2017. New species of Parotocinclus (Siluriformes: Loricariidae) from coastal drainages of Rio de Janeiro, southeastern Brazil. Zootaxa 4232: 260–270.

Abstract

A new species of Parotocinclus is described from tributaries of rio São João, an Atlantic coastal river of Rio de Janeiro, southeastern Brazil. The new species is distinguished from its congeners by the possession of a triangular patch of dark pigmentation on the anterior portion of the dorsal-fin base, a fully developed adipose fin, complete exposure of the ventral surface of the pectoral girdle, and a distinctive pigmentation pattern of the caudal fin. The caudal fin has a hyaline background with a large black blotch covering its anterior portion, tapering irregularly through distal portions of the ventral lobe with a hyaline rounded area, and a small patch of dark pigmentation on distal portions of the dorsal lobe.

As far as I can tell, this new fish is represented currently by none of the "sp(#)" or "sp_rio XXX." I'm basing this on catch location to exclude some of the undescribed entries, and by appearance differences for the other undescribed fish. Is this correct?

Cheers, Eric

Yup. The new species doesn't look like anything in the Cat-eLog.
