Habitat: Microglanis malabarbai, is described from the Rio Ijuí drainage, tributary of the middle Rio Uruguay, Rio Grande do Sul, Brazil. The new species is distinguished from all other Microglanis species by the caudal fin colour pattern, almost completely black, with a narrow vertical white band across central portions of the caudal-fin rays. Furthermore, it is distinguished from M. cottoides and M. eurystoma, both from rio Uruguay drainage, by head length, maxillary barbel length, internareal distance, and number of lateral-line pores, and from M. cibelae from the coastal drainages of northern Rio Grande do Sul and southern Santa Catarina states, by head length, maxillary barbel length, and body width. Aquarium Care: Microglanis malabarbai is one of twenty six, small to medium sized pims, found in this family, and as such is a good addition to the medium sized community tank, and will not harm the occupants unless they are small enough to fit into its mouth such as newly born fry and young fish. Diet: Can be fed a varied diet of tablet food, pellets, worm foods and frozen food such as bloodworm. Remarks: 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 are (all lots deposited at MCP): Cichlasoma dimerus, Crenicichla scotti, Heptapterus mustelinus, Hisonotus sp., Rhamdia quelen, and Rineloricaria sp. (Bertaco, V.A. and A.R. Cardoso, 2005).
