Mattos, JLO, FP Ottoni & MA Barbosa, 2013. Microglanis pleriqueater, a new species of catfish from the São João river basin, eastern Brazil (Teleostei: Pseudopimelodidae). Ichthyological Exploration of Freshwaters 24: 147–154.
Abstract
Microglanis pleriqueater, new species, is described from the São João river basin, southeastern Brazil. It is similar to M. nigripinnis and M. ater in general colour pattern and body morphology. The new species differs from all its congeners, except M. ater and M. nigripinnis, by having the body and dorsal fin almost black or dark brown. It differs from M. nigripinnis and M. ater by having a third whitish brown band on flank, located on the origin of the caudal peduncle, presence of a rounded light brown mark on adipose fin posterior region, presence of a large pale brown region on dorsal fin, and 15-16 principal caudal-fin rays. In addition, M. pleriqueater is distinguished from M. nigripinnis by having pectoral fin light brown, and pectoral-fin counts I,6; and from M. ater by having 13-14 anal-fin rays.
