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.
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.
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).
