is a small species with a maximum size in the type series of 52.5 mm SL. Body cylindriform; inner surface of lips with transverse plicae. Counts and proportional measurements are presented in Table 1. Two pairs of barbels present: maxillary barbels well developed, but mostly hidden with only tip reaching beyond jaw articulation (Fig. 3); rostral barbels small. Anterior nasal opening with well developed tube. Eyes large, in lateral position: visible in dorsal but not in ventral view. Prominent breeding tubercles sometimes developed.

Three of the unbranched rays supranumerary, at least anterior one only visible in cleared and stained specimens or x-rays. Pectoral fins low, laterally positioned on the body, reaching level of dorsal-fin base. Pectoral fin with 16 to 23 rays. Pectoral and pelvic fins broadly separated. Pelvic fins insert about in middle of dorsal fin and reach beyond anus. Anus 3 to 4 scale rows in front of anal fin. Pelvic fins consist of one unbranched, seven branched and again one unbranched ray. Caudal fin deeply notched with pointed dorsal and ventral lobes, consisting of 10 upper and 9 lower principal rays plus 10 - 11 upper and 7 - 10 lower procurrent rays. 39 to 41 scales in the lateral line, 5.5 scale rows between dorsal-fin origin and lateral line and 3.5 to 4.5 scales between lateral line and origin of pelvic fin. Vertebral column with 38 vertebrae (18 - 19 abdominal; 19 - 20 caudal vertebrae). Dorsal fin inserts after neural spine of vertebra number nine; anal fin inserts after haemal spine of vertebra 26 to 28, usually 27.</paragraph>

Towards to horizontal septum the coloration becomes more greenish. A narrow, almost golden reflecting band about one scale row above the horizontal septum. Along flank a broad grey band continuing on to the head. Belly clear white; some melanophores only on ventral side of snout. Fins transparent; only some melanophores in dorsal fin and along upper and lower border of caudal fin. Upper half of eye conspicuously orange (Fig. 2). Fixed specimens with brown back without reflections; belly pale. Grey band along flank hardly visible and completely absent from head. Fins less transparent and orange tint of eye absent.</paragraph>
