Microcambeva


Microcambeva is a genus of catfishes of the family Trichomycteridae. It includes three species, M. draco, M. barbata and M. ribeirae.

Species

There are currently three recognized species in this genus:
Microcambeva is thought to be widespread along coastal basins of southern, southeastern, and eastern Brazil. M. barbata originates from Atlantic coastal drainages of Rio de Janeiro and Espírito Santo states in Brazil. M. ribeirae originates from the Ribeira do Iguape River basin of southeastern Brazil. Two undescribed species of Microcambeva are known from the Doce River basin in Minas Gerais state and Jucuruçu River in Bahia state.

Description

The two currently described species of Microcambeva have similar general morphology. M. ribeirae has a maximum recorded length of 4.8 centimetres SL. M. ribeirae is distinguished from M. barbata by a series of morphological features, including the extent of the nasal barbels, the position of the eye, the first pectoral fin ray being shorter than the posterior ones, the anal fin origin behind the vertical through the base of the last dorsal fin rays, and others.

Habitat

M. ribeirae has been found in clear, shallow streams with a gray, sandy bottom in which the specimens were found entirely buried except for snout and barbels.
