are from nearby, at the confluence of the Culuene<br />

and Sete de Setembro rivers, and without precise<br />

locality in the Rio Batovi (shown as Rio Tamitatoala<br />

on current maps). The Córrego do Gato is<br />

also the type locality of Crenicichla rosemariae<br />

(<strong>Kullander</strong>, 1997).<br />

Etymology. Named for Mirian Leal-Carvalho,<br />

who participated in the collection of part of the<br />

type series.<br />

Notes. Small specimens of C. mirianae display an<br />

indistinct continuous lateral band from snout to<br />

caudal peduncle (Fig. 37), and retain this band as<br />

adults displaying as irregular blackish blotches<br />

arranged in a narrow band connecting the three<br />

lateral ocellar blotches and continuing onto the<br />

caudal peduncle. This development of the colour<br />

pattern is similar to that of C. intermedia, but in<br />

that species, the juvenile lateral band is wider and<br />

more prominent, and whitish spots covering body<br />

and head of C. mirianae are absent. Cichla intermedia<br />

lacks the prominent lateral ocelli of C. mirianae<br />

and has about 6 narrow vertical bars across the<br />

side. Adult C. mirianae are similar to C. orinocensis<br />

in possession of three prominent ocellated blotches<br />

along the side, but juvenile C. orinocensis do<br />

not possess a continuous horizontal band along<br />

the side.<br />

The Cichla material from the upper Rio Tapajós<br />

and upper Rio Xingu drainages are referred<br />

to the same species. There are no morphometric<br />

or meristic differences between the two geographical<br />

samples. Whereas all specimens from<br />

the Rio Tapajós drainage display prominent<br />

ocelli on the side from small sizes, the lateral<br />

blotches are less prominent in Xingu specimens,<br />

and also large specimens possess distinct white
