Description
The two currently described species of ''Microcambeva'' have similar general morphology.
''M. ribeirae'' has a maximum recorded length of 4.8
centimetres (1.9
in)
SL.
''M. ribeirae'' is distinguished from ''M. barbata'' by a series of morphological features, including the extent of the
nasal barbels (to the nostril instead of the eye), the position of the eye (posterior half of head instead of on central portion), the first pectoral fin ray being shorter than the posterior ones (instead of the first ray being elongate and forming a prominent filament), the anal fin origin behind the vertical through the base of the last
dorsal fin

rays (instead of at this vertical), and others.
Habitat
''M. ribeirae'' has been found in clear, shallow streams (about 60 cm or 24 in deep) with a gray, sandy bottom in which the specimens were found entirely buried except for snout and barbels.
