Diagnosis. Similar to C. jariina, C. pinima, C. temensis,
and C. thyrorus in possession of four horizontal
rows of light spots along side in subadults
and large females, and prominent black, lightmargined
vertical bars or blotches in adults. Scales
in E1 row ca 100-110, exceptionally 95-114, vs.
77-90 in C. thyrorus. Lateral line nearly always

discontinuous, vs. usually continuous in C. temensis
and C. thyrorus. Vertical bars of breeding
specimens ocellated and modified, typically with
small blotch close to dorsal fin base, below that
ocellated vertical bars, or bar 1 with two separate
or contiguous blotches, one on midaxis and one
under pectoral fin, posterior bars rarely modified
into blotches (vs. typically three vertical rows of
3, 3, and 2 blotches in C. jariina and C. thyrorus).
A dark blotch at anterodorsal process of preopercle
is nearly always present in adults over 200 mm
SL (vs. usually absent in C. pinima).
Distinguished from C. pinima also by smaller
scales (95-114 vs. 86-105), but ranges overlap, and
consistent presence of row of light spots along
abdominal side (vs. commonly absent in C. pinima).
Breeding C. pinima have three ocellated bars
which continuous above upper lateral line when
extending above it, and usually no isolated
blotches on dorsum; subadult and adult specimens
of C. pinima possess an ocellated blotch
dorsally in bar 3, which never occurs single in
C. vazzoleri but only in breeding pattern together
with other ocellated blotches. Cichla temensis
generally possesses more E1 scales, 98-128, usually
more than 110, and vertical bars of adults
entire, extending from dorsum to abdominal
side.
Description. Refer to Figs. 76-80 for general shape
and colour pattern, Table 24 for morphometrics,
and Tables 2-10 for meristics. Specimens 26 to
410 mm SL were available from the lower Rio
Trombetas (downstream of Cachoeira Porteira).
Most are adults in breeding colouration. The
description is based primarily on the adult Trombetas
material. Specimens 36-335 mm were available
from the Rio Uatumã, and the smaller size
range was used in the description below.
Relatively elongate (depth 25.2-29.3 % SL,
N = 20, 200-410 mm SL). Predorsal contour ascending
gently curved; or in large males straight, with
soft nuchal swelling projecting from predorsal
midline. Maxilla reaching to vertical from anterior
margin or middle of orbit, lower jaw distinctly
prognathous, its articulation below middle
of orbit. Lateral line usually discontinuous, bilaterally
continuous in two of 33 specimens; free
ends of discontinuous sections usually with long
overlap.
Dorsal fin spines 4-5 longest: soft dorsal fin
rounded, not reaching to caudal fin base. Soft anal
fin rounded, reaching halfway to middle of cau-
