soft rays: 8. Processus dentiformis present; 9+8 branched caudal rays; 8 1/2 branched dorsal rays; no suborbital flap in males; incomplete lateral line reaching about anal fin origin; two black spots at base of caudal fin; 8-11 bars on body; caudal fin emarginate to slightly forked (Ref. 39226).
Found over pebbles in small shallow streams. A female measuring 4.56 cm SL contained ovulae of about 0.9 mm in diameter. Its stomach contained insect remains (Ref. 39226).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00268 - 0.01487), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (24 of 100) .
