ABSTRACT
Trichomycterid catfishes of the Sarcoglanidinae, which includes
small-sized species living in sandy river substratum, have been
poorly represented in collections. We herein describe two new
species of the sarcoglanidine genus Microcambeva, endemic to
river basins draining the Brazilian Atlantic Forest. The presence of
a distal widening on the posterior process of the autopalatine and
a rudimentary anterior autopalatine ossification shared by the two
new species, M. mucuriensis sp. nov. from the Rio Mucuri
and M. jucuensis sp. nov. from the Rio Jucu basin, and M. draco
from the Rio Jucuruçu basin indicates that these three species are
more closely related to each other than to other congeners.
Microcambeva mucuriensis seems to be more closely related
to M. draco than to M. jucuensis in that the first two species
share the presence of a well-developed anterior process of the
interopercle. The two new species are also distinguished from
congeners by the number of opercular odontodes and premaxillary
teeth, and the relative size of the sesamoid supraorbital. Available
evidence taken from this study and previous reports indicates that
different sarcoglanidine lineages have adapted to live in distinct
riverine habitats, with species of Atlantic Forest Microcambeva
inhabiting clearwater streams and Amazonian sarcoglanidines
found in tea-stained acidic-water streams.
