NEOTROPICAL ICHTHYOLOGY Volume 10 Number 2, June 29, 2012AbstractCrenicichla chicha
, new species, occurs in clear, fast-running waters with rocky substrates in the rio Papagaio and tributaries.
It is distinguished from all other Crenicichla
species by the combination of two character states: infraorbitals 3 and 4 coossified
(vs. separated) and 66-75 scales in the row immediately above to that containing the lower lateral line (E1 row scales).Crenicichla chicha
shares a smooth preopercular margin, co-ossification of infraorbitals 3 and 4, and some color features withC. hemera
from the adjacent rio Aripuanã drainage, rio Madeira basin. It differs from Crenicichla hemera
in more E1 scales (66-
75 vs. 58-65) and presence of a conspicuous black narrow stripe running from infraorbital 3 obliquely caudoventrad toward the
preopercular margin vs. a rounded and faint suborbital marking present on infraorbitals 3-4. Examination of the type series and
additional material from the rio Aripuanã confirms that Crenicichla guentheri
Ploeg, 1991 is a junior subjective synonym of C.
