Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 1; Dorsal soft rays (total): 3; Anal soft rays: 75 - 79; Vertebrae: 58. Snout length 33.1-34.8% SL; vomerine teeth in 2 distinct elliptical patches; a distinct nuchal concavity; and mandibular barbels reaching beyond anterior base of anal fin. Males with pectoral spine enlarged and broad, somewhat flattened dorsoventrally with 7-9 posterior dentations, increasing in size distally; proximal articulated segments with 6-9 well-developed posterior dentations. Female or juvenile with spine slender and with no dentations; 6 articulated segments present. Mandibular barbels one pair, located slightly anterolateral to gular fold. Branchiostegal rays 9-10.
Inhabits mainstreams and tributaries (Ref. 58784). Feeds on insects and small shrimps (Ref. 58784).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00278 - 0.01137), b=3.00 (2.83 - 3.17), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 4.0 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref.
