two middle rows may be contiguous to some<br />

extent. Caudal ocellus dark brown, located above<br />

mid-axis, with yellow peripheral fields but not<br />

completely ocellated. Light spots absent from<br />

nape and cheeks.<br />

Specimens over 200 mm SL (Figs. 87-89) with<br />

light brown side, slightly darker dorsally. Halter<br />

stripe dark brown, extending back to jaw articulation.<br />

Preorbital stripe blackish, well expressed.<br />

Dark brown to blackish wide stripe with wide<br />

white margin from eye to opercular tip, not interrupted<br />

over preopercle. Horizontal lateral band<br />

not evident except occasionally as narrow dark<br />

brown stripe dorsally on caudal peduncle. Vertical<br />

bars faint. White spots in two horizontal rows<br />

along back, one row along abdominal side and<br />

two rows representing rows marginal to absent<br />

lateral band. Spots generally roundish and distinct<br />

except in latter rows in which spots elongate or<br />

to some extent confluent. Cheek, gill cover, and<br />

top of head with numerous white spots increasing<br />

in number and decreasing in relative size with<br />

increasing specimen length. Dorsal fin grey with<br />

two rows of white spot on spinous portion, four<br />

rows of white spots on soft portion. Anal fin<br />

whitish, shading to brownish distally. Pelvic fin<br />

brownish on lateral side, otherwise whitish.<br />

Caudal fin with round, dark brown spot, completely<br />

ringed with yellow stripe. Dorsal lobe<br />

otherwise brownish with about six rows of whitish<br />

spots; ventral lobe brownish or yellowish.<br />

Large adults, over 300 mm SL (Fig. 89), have<br />

the postorbital stripe partly fragmented and with<br />

a few additional black spots dorsally on subopercle<br />

and cheek, all with white borders. Anal fin<br />

brownish. Ocellar markings absent other than<br />

those formed by postorbital blotches and caudal<br />

spot. Specimens clearly representing breeding<br />

colour or sexual dimorphism absent in preserved<br />

material.<br />

Live and fresh preserved colours. Juvenile photographed<br />

at Rio Cadauiri yellowish with white<br />

underside and black lateral stripe.<br />

Large adults, known or estimated to be over<br />

500 mm SL apparently sexually dimorphic. Specimens<br />

probably representing males, with well<br />

developed nuchal hump, yellowish with greenish<br />

grey back and hump. Vertical bars evident, though<br />

not contrasted, light spots only indicated on side<br />

or, usually, completely absent from head, body<br />

and fins. Lower half of caudal fin, anal and pelvic<br />

fins, a band along abdominal side, branchiostegal<br />

membrane, and iris bright red or orange. Large<br />

specimens without hump, assumed to be females,<br />

with white spots on body, head and fins, but fins,<br />

branchiostegal membrane, side and iris red as in<br />

males. Vertical bars in those large adults proportionally<br />

wider than in young specimens; of about<br />

uniform width across side, and may appear to<br />

have slightly lighter margin, but do not form<br />

ocellar markings. Black, light-margined postorbital<br />

markings well evident and contrasted especially<br />

in large males.<br />

Geographical distribution. Restricted to blackwater<br />

rivers and their tributaries (Fig. 75), recorded<br />

from many localities along the Rio Negro<br />

in Brazil and Venezuela, many localities in the<br />

Rio Orinoco drainage, a few localities only in the<br />

Rio Branco drainage. Along the Rio Solimões-<br />

Amazonas recorded from Tefé, Rio Puraquequara,<br />

lower Rio Uatumã, Rio Preto da Eva, and Lago<br />

Saracá, all black-water habitats. Reported by<br />

Lowe-McConnell (1969) from the Rio Branco<br />

drainage in Guyana.<br />

An adult specimen from the Rio Jamari (INPA<br />

3493) and a small specimen from Lago Genipapo<br />

(INPA uncat.) on the Rio Aripuanã are questionably<br />

referred to C. temensis, but regrettably there<br />

is nearly no other Cichla material available from<br />

the Brazilian portion of the Madeira drainage to<br />

permit an understanding of the distribution of<br />

C. temensis in this region.<br />

Local names. Sarabiana (Natterer, in Heckel,<br />

1840: 413, Rio Negro); tucunaré (Natterer in Heckel,<br />

1840: 409, Boa Vista area); pintado (Schomburgk<br />

in Jardine, 1843:145, Rio Negro); Lucanari<br />

Grande (Schomburgk, in Jardine, 1843: 151, Rio<br />

Negro); tucunaré sorubiana (Magalhães, 1931:<br />

225, errata, Rio Negro); pavón pintado, pavón<br />

trucha, pavón venado (Román, 1981: 76, Venezuela);<br />

Pavón cinchado (large specimens; Román,<br />

1981: 82).<br />

Both the appelation pintado and sorubiana<br />

refer to the pimelodid catfish species Pseudoplatystoma<br />

fasciatum, known as surubi (Tupi-Guarani)<br />

or bagre pintado (Spanish).<br />

Notes. The smallest specimen (Fig. 81) was identified<br />

by the very small scales, estimated at 100<br />

in the E1 row but a precise count not possible.<br />

None of the preserved specimens show a<br />

nuchal protuberance; sport fishing web sites,<br />

however, frequently display large C. temensis,
