Geographical distribution. Known from the

Teles Pires rivers, and from the middle and upper
Rio Xingu drainage, in the Fresco, Batovi, Culuene
and Suiá-Missu rivers (Fig. 9).
Lowe-McConnell (1991), reported Cichla ‘xingu’
as abundant in the Rio Suiá-Missu, and
present in Suiá-Missu lakes, and observed in the
Córrego do Gato (also a tributary of the Rio Suiá-
Missu). The only specimen preserved, however,
comes from the Córrego do Gato. Other records
