Fig. 75. Collecting localities of Cichla temensis, C. pinima (including translocation), C. vazzoleri, and C. cf. pinima.<br />

A symbol may cover more than one collecting site.<br />

Cichla pinima and C. vazzoleri share a distinctive<br />

adult breeding colour pattern, best expressed<br />

in males. The vertical bars become deep black<br />

and the dorsal portion of each bar may separate<br />

as a dark ocellated blotch above the upper lateral<br />

line, regularly in C. vazzoleri but rarely in<br />

C. pinima. In C. pinima the middle portion of the<br />

first bar forms a large prominent ocellus and the<br />

ventral part becomes obsolete or forms a blotch<br />

under the pectoral fin; the middle portion of bar 2<br />

may be slightly expanded and blotch-like, but<br />

usually there is a complete ocellated vertical bar<br />

extending to the abdominal side; the third bar,<br />

below the dorsal blotch, remains vertically extended,<br />

and is usually contiguous with the dorsal<br />

blotch. In C. vazzoleri the pattern is similar to that<br />

of C. pinima, although the vertical bars are usually<br />

narrower, and the middle ocellus in bar 1 is<br />

not as well formed as in C. pinima.<br />

All populations sharing the development of<br />

the blotch in the dorsal portion of bar 3 were assigned<br />

to C. pinima, although samples other than<br />

those from the Tapajós and Xingu river drainages<br />

generally do not contain large breeding males<br />

in which breeding colour could be verified. Samples<br />

from southern tributaries assigned to C. pinima<br />

on the basis of colour markings turned out to<br />

be highly variable in fin ray and particularly scale<br />

counts. E1 row counts show some geographic<br />

variation and are generally higher to the west and<br />
