🐟 Physical Description

It possesses the characters of the sandy group and it can be diagnosed within the species of the sandy group by having the following characters: elongate naked area at tip of snout reaching the most anterior pore of the infraorbital sensory canal (vs. oval naked area at tip of snout, not reaching the most anterior pore of the infraorbital sensory canal in Rineloricaria quadrensis, Rineloricaria misionera, and Rineloricaria strigilata); plain, light brown background color (vs. with numerous dark and vermiculated spots on a light brown background in Rineloricaria strigilata); shallower body, depth at anal-fin origin 6.0-7.4 (vs. 7.9-9.4% SL in specimens above 10 cm SL in Rineloricaria cadeae); dorsal caudal-fin unbranched ray not prolonged (vs. dorsal caudal-fin unbranched ray produced as a short filament in Rineloricaria catamarcencis); usually with three series of plates between the lateral abdominal plates (vs. four of five series in Rineloricaria catamarcensis and Rineloricaria felipponei); comparatively larger plates covering the pectoral girdle, usually 5-6 plates versally and usually three series of plates between the lateral abdominal plates (vs. many small platelets covering the pectoral girdle, usually more than 15 platelets, and four of five series of plates between the lateral abdominal plates in Rineloricaria pareiacantha and Rineloricaria thrissoceps) .: elongated.
