Tends to be gregarious as individuals were observed in dense group under large stones (Ref. 75872). Bockmann, F.A. and A.M.

Differs further from other species of Rhamdella by the following combination of characters: barbel tip reaching from the base of pectoral-fin ray in a specimen measuring 8.80 cm SL, to the posterior portion of opercular region, not surpassing the branchial slit, in a 15.75 cm SL specimen; horizontal eye diameter 20.6-23.9% of HL; interorbital distance 17.9-20.7% of HL; snout profile slightly convex but almost straight; branchiostegal rays seven, branchiostegal membranes not reaching the basal part of the first pectoral-fin ray in most specimens; interdorsal length 7.6-11.3% of SL; adipose-fin base length 36.0-41.6% of SL; anal-fin base length 16.6-22.0% of SL; anal-fin rays 16-18, commonly 17; and length of ventral caudal-fin lobe is 55.8-65.5% of length of dorsal lobe in males; snout length 37.9-43.2% of HL; pelvic fin length 13.3-16.9% of SL; a dense concentration of long and slender papillae on the lateral body surface in the pectoral and abdominal regions, most conspicuous near the lateral line, resulting in a hairy aspect; and by the presence of a distinct narrow dark mid lateral stripe (Ref. 75872).Description: Dorsal fin with 1 long unbranched and 6 or 7 branched rays; Anal fin with 16, 17, or 18 rays, including 10 or 11 branched rays (vi,10, v,11, vii,10, vi,11, or viii,10); Pectoral fin with 1 unbranched and 8, 9, or 10 branched rays; Pelvic fin with 6 rays (Ref. 75872).
