Geophagus brasiliensis ( Quoy & Gaimard, 1824) Figure 3T

Original description. Chromis brasiliensis Quoy and Gaimard 1824: 286 .

Material examined. BRAZIL • 10, 30.2−60.7 mm SL; São Paulo state, Pongaí, Córrego da Mina ; 21°43′45″S, 049° 21′29″W; 24 May 2018; leg. Silva G.S.C. and Reia L. (LBP 26615) .

Identification. Body deep; mouth terminal; premaxilla with three and dentary with two to four teeth rows. Upper lateral line with 18 to 20 perforated scales; lower lat- eral line with 11 to 13 perforated scales; longitudinal series with 26 to 29 scales; four horizontal scale rows above upper lateral line; five horizontal scale rows be- low lower lateral line. Overall body coloration silver to greenish; six to eight conspicuous dark bars; dark conspicuous blotch in middle-body; dark vertical bar across eye; longitudinal blue stripes rows on trunk; blue blotches on head and fins; eyes and fins reddish.

Remarks. Our results showed variation in the number of pored scales of the upper lateral line and total scales in the longitudinal series of G. brasiliensis in comparison to the description by Ota et al. (2018) for specimens from the upper rio Paraná floodplains (18−20 vs 17−19 and 26–29 vs 24−27, respectively). We also observed a single specimen with 13 pored scales in the upper lateral line and a non-pored lower lateral line. Our observations increase the known range for these counts in G. brasiliensis in the the upper rio Paraná.
