Several light spots on proximal half of caudal fin.<br />

Large, partially confluent black spots with white<br />

or yellow margin on abdominal side between<br />

pectoral fin and middle vertical bar. Nuchal hump<br />

prominent, dark grey.<br />

Breeding female NRM 18023 yellowish to<br />

golden on side yellowish on cheek and gill cover,<br />

with pattern as preserved specimen. Lower jaw,<br />

chest, abdomen and ventral side of caudal peduncle<br />

white. Branchiostegal membrane orange.<br />

Light spots posterodorsally on side, light ring of<br />

caudal ocellus and spots on anal fin yellow. Light<br />

spots on pelvic fin white.<br />

Other large adults, without nuchal hump,<br />

greyish to olive on side, lower part of head, abdomen<br />

and ventral margin of caudal peduncle white;<br />

greyish on side next to anal fin base. Orange stripe<br />

from angle of mouth to lower part of subopercle,<br />

and often indistinct pale orange along abdominal<br />

side. Spots on fins white. Anal fin and lower lobe<br />

of caudal fin maroon.<br />

Etymology. Named for Dieter Kelber, in recognition<br />

of his promotion of Cichla as sport fishes, and<br />

for supporting our study with information and<br />

images of the tucunaré amarela (C. kelberi) and<br />

tucunaré azul (C. piquiti).<br />

Geographical distribution. Rio Araguaia drainage<br />

and the lower Rio Tocantins drainage (Fig.<br />

23). Introduced in reservoirs in Rio Grande do<br />

Norte, Minas Gerais and Ceará (Chellappa et al.,<br />

2003, as C. monoculus; Fontenele, 1948, as C. ocellaris),<br />

in the Rio Paraíba do Sul (State of Rio de<br />

Janeiro), and the Rio Paraná.<br />

Kelber (1999) listed Tucunaré amarela from<br />

the Itaipu, Porto Primavera, Jupiá, Três Irmãos,<br />

Ilha Solteira, São Simão, Porto Colômbia, Volta<br />

Grande, Jaguara, Estreito, Promissão, Igaratá and<br />

Paraibuna dams in the Brazilian Paraná basin, the<br />

Funil and Ribeirão das Lajes dams in the Rio<br />

Paraíba do Sul drainage, the Xingó dam in the<br />

Rio São Francisco drainage, the Pacoti-Riachão<br />

dam near Fortaleza in Ceará, the Serra da Mesa<br />

dam in the Rio Tocantins drainage. The Tucunaré<br />

amarela corresponds to C. kelberi according to<br />

photographs provided by D. Kelber.<br />

Local names. Tucunaré amarela (São Paulo,<br />

Brazil; Kelber, 1999), Tucunaré comum (Northeast<br />

of Brazil; Fontenele, 1948).<br />

Ichthyol. Explor. Freshwaters, Vol. 17, No. 4<br />

Notes. Cichla kelberi has long been confused with<br />

C. monoculus (e.g., Fontenele, 1958, as C. ocellaris),<br />

which it resembles in shape and general colour<br />

pattern. We have not found any diagnostic character<br />

other than the light-spotted pelvic, anal and<br />

caudal fins, to separate the two species, but since<br />

this character state is unique in the genus, we are<br />

confident about species distinctness. The lateral<br />

scale count is within the higher range of C. monoculus,<br />

and below the range of C. pleiozona.<br />

The type material of Cycla toucounarai is represented<br />

by two preserved specimens, MNHN<br />

A.9490, labelled simply as coming from the<br />

“Amazone”, although the description (Castelnau,<br />

1855) also mentions “le lac des Perles de la province<br />

de Goyaz”, and the Rio Tocantins. They were<br />

referred to C. monoculus by <strong>Kullander</strong> (1986). Both<br />

specimens have characteristic blotches on the<br />

abdominal side posterior to the pectoral fin base.<br />

The larger syntype (<strong>Kullander</strong>, 1986: pl. 4 fig. 1)<br />

is a male with nuchal hump, the smaller specimen<br />

a female. The pigmentation of the smaller specimen<br />

is slightly faded on both sides, and it shows<br />

no traces of light spots on the pelvic, anal, or<br />

caudal fins. The larger specimen possesses a black<br />

occipital stripe, three prominent vertical bars<br />

dorsally on the side, and trace of a dark blotch<br />

dorsally at the root of the caudal peduncle. The<br />

pigmentation of the right side is significantly<br />

faded, but the dark pigmentation is relatively well<br />

preserved on the left side. The anal fin is brownish<br />

with indicated lighter patches distally on the<br />

scaled portion of the anterior five soft rays. The<br />

ventral half of the caudal fin is brownish with<br />

indistinct lighter mottling but without light distinct<br />

spots. The pelvic fin is brownish anteriorly<br />

with two lighter patches on anterior soft rays. The<br />

caudal spot is ringed with a prominent silvery<br />

ring in both specimens.<br />

Castelnau’s description and drawing disagree<br />

with the preserved syntypes. The drawing shows<br />

a specimen without occipital bar, and without<br />

dark blotches on abdominal side, but with three<br />

distinct vertical bars below the dorsal fin and one<br />

anteriorly on the caudal peduncle, and some red<br />

spots on the anal fin. The description apparently<br />

partly refers to the drawing, but the total length<br />

agrees with the larger syntype. Both syntypes<br />

have D. XVI.17, the drawing shows XV.18, Castelnau<br />

gives XV.17. He counts A. II.11, we count<br />

A. III.11. The pectoral fin count, 14 is in agreement.<br />

We count approximately 79 (larger syntype) and<br />

71 (smaller syntype) scales along the midline, but
