【 摘 要 】

Serrapinnus sterbai spec. nov. from the eastern parts of Brazil (probably Araguaya drainage) is described. Typically thereare (1) a black longitudinal band from the eye to the basis of caudal-fin, (2) an incomplete lateral line with eight to 12 poredscales, (3) 32 to 34 scales in a longitudinal line, (4) 21 to 23 anal-fin rays (total), (5) 32 to 33 vertebrae (4+9–10+18 – 20),(6) 14 to 16 gill-rakers on the first left arch (5 – 6 /9–10), (7) five seven- to ninecuspid premaxillary teeth, (8) two to threesevencuspid maxillary teeth, (9) five sevencuspid mandibulary teeth, (10) head relatively small (3,93 to 4,71 times in SL)and (11) body depth moderately high (2,63 to 3,18 times in SL). The species is easy to identify from all other members ofthe genus by its coloration. Cheirodon gracilis Géry, 1960 and Cheirodon littoris Géry, 1960 are transferred into the genusSerrapinnus.
