In 70% ethanol: chestnut brown on dorsal and lateral surfaces of head and body, fading to light brown on ventral region. Dorsal surfaces of head and body with indistinct light brown patches on supraoccipital spine and immediately anterior to dorsal-spine base. Lateral surfaces of body with very faint light brown patches: one patch immediately posterior to last dorsal-fin ray and an elongate ovate spots on side of body immediately ventral to origin of adipose fin. Dorsal and anal fins with chestnut brown base and subdistal band. Adipose fin chestnut brown, with light brown anterior margin and margin along posterior twothirds of fin. Caudal fin chestnut brown, with small hyaline spot on lobes near horizontal midline and hyaline distal margin. Dorsal surfaces of pectoral and pelvic fin bases chestnut brown, with hyaline distal margin; ventral surfaces hyaline. Maxillary and nasal barbels chestnut brown dorsally and light brown ventrally.
