Abstract

A new species of Farlowella (Siluriformes: Loricariidae: Loricariinae: Farlowellini) from the Parapetí River (Iténez basin) and Grande River (Mamoré basin), in the Bolivian Amazon Basin, is described. Farlowella guarani sp. n. belongs to the nattereri species-group defined by Retzer & Page (1996), and has been identified and differs from its congeners by having short snout-mouth length (<50% of head length), snout- mouth length 30.5–73.5 % of pectoral fin length in adults, fourth row of anterior lateral plates keeled, pectoral fin length ˃100 % of pectoral fin origin to pelvic fin origin length, possession of 22–27 abdominal plates, 22–31 upper and 20–28 lower jaws teeth, presence of dark dots on head and dorsal portion forming longitudinal fragmented stripes. This is the first record of Farlowella in the Parapetí River and represents the record at highest elevation (>900 m) of the genus in South America. F. guarani is the second species recently described for the Bolivian Amazon, after F. altocorpus, and both are tentatively restricted to Andean portions of the Madera River watershed.
