Corumbataia was proposed
by Britski (1997) when describing Corumbataia
cuestae from the Upper Paraná basin in
the Rio Tietê and Corumbataia
from the Rio Araguaia and Rio Tocantins basins. Description:
This genus was delimited by an exposed portion in
the middle of the scapular bridge formed only by the
coracoid; compound hypurals 1 and 2 completely fused
to the compound hypurals 3-5; atrophic maxillary barbel,
and anastomosis of the infraorbital and otic sensory
canals over the pterotic-supracleitrum (Britski, 1997).
Four species were subsequently described: C. britskii
Ferreira & Ribeiro, 2007, C. veadeiros
Carvalho, 2008, C. lucianoi Silva, Roxo,
Souza & Oliveira, 2018 and C. liliai
Silva, Roxo, Souza & Oliveira, 2018. Additionally,
two species formerly described in Gymnotocinclus
were transferred to Corumbataia by Roxo et
al. (2019): C. anosteos (Carvalho, Lehmann
& Reis, 2008) and C. canoeiro (Roxo,
Silva, Ochoa & Zawadzki, 2017). This genera contains
six species (2020) C. tocantinensis Britski,
1997, C. cuestae Britski, 1997, C. anosteos
(Carvalho, Lehmann A. & Reis, 2008), C. britskii
Ferreira & Ribeiro, 2007, C. canoeiro
(Roxo, Silva, Ochoa & Zawadzki, 2017), and C.
veadeiros Carvalho, 2008. They are an intermediate
between the genera's, Parotocinclus and Otocinclus
and don't posses an adipose fin. and the body is stockier
than these two previous genera. Colouration:
Corumbataia species have a dark band along the
body. Sexual Differences: Males have
longer pectoral fins and also differing morphology
of the genital papilla. Aquarium Care:
Quite problematic to keep due to the cooler temperatures
and having to facilitate a flow current in the water.
Diet: Aufwuch feeder with the usual
aquarium fare of flake and tablet foods.
South America:Tietê River basin, Brazil. Type
locality: Cachoeira de Analândia, rio
Corumbataí, Analândia, SP [Brazil].
