ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ): 7-8; ຄີກົ້ນຂອງປາ: 16 - 18. Presence of a distinct and large ovoid area in the supraorbital laterosensory canal between the frontal and sphenotic delimited by the apparently slender dorsal walls of these bones and with foramen for a laterosensory branch. 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).
Occurs over rocky bottoms in a clear water stream, approximately 0.5 - 1 m deep, with pools around 3 m deep, running through a densely forested area (Ref. 75872). Tends to be gregarious as individuals were observed in dense group under large stones (Ref. 75872).
