Identification The genus Microglanis was described by Eigenmann (1912) to include small pimelodids with the head as wide as long, the skull covered by skin only; the occipital crest small; frontal fontanel not extending much if any behind the eye, and a minute occipital fontanel sometimes present; eye without a free orbital margin; dorsal and pectoral spines well developed; and premaxillary patches of teeth without backward projecting angles.

This species is distinguished from all other Microglanis species by the caudal fin color pattern which is almost completely black with a narrow vertical white band across central portions of the caudal-fin rays.
General Remarks Per the original description, all specimens of M. malabarbai were caught under dead tree branches and leaves in dark water, lentic stretches of shallow streams, with sand and mud on the bottom, and moderate amount of riparian vegetation. The rio Ijuí drainage is surrounded mainly by soybean, wheat, and pasture plantations, with narrow areas of original vegetation on stream margins. Other species collected in same habitat with M. malabarbai were: Cichlasoma dimerus, Crenicichla scotti, Heptapterus mustelinus, Hisonotus sp., Rhamdia quelen, and Rineloricaria sp.
