Etymology: Oreoglanis: Greek, oreos = mountain+Greek, glanis = Latin, aurum = gold + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); vicinus: The specific name comes from the Latin adjective vicinus (neighboring), in allusion to the close proximity of distributional ranges it shares with two other congeners (Oreoglanis colurus and Oreoglanis tenuicauda).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Asia: upper reaches of the Nan River drainage, itself a tributary of the Chao Phraya River in northern Thailand.

Morphology | Morphometrics
soft rays: 4 - 5;
Vertebrae: 33 - 37. Belongs to the Oreoglanis delacouri species group as it lacks a distinct median notch on the posterior margin of the lower lip. Can be distinguished from other members of the genus in having the following combination of characters: maxillary barbel with rounded tip, dentary tooth patches separated by approximately one-third to half their width, pectoral fin reaching beyond pelvic-fin origin, body depth at anus 10.0-12.6 % SL, adipose fin confluent with upper procurrent caudal-fin rays, caudal peduncle length 15.1-21.2 % SL, caudal peduncle depth 5.0-6.9 % SL, caudal peduncle depth 2.51-3.80 times in its length and lunate caudal fin with upper and lower first principal ray of approximately the same length (Ref. 83406).
Occurs in rocky, fast-flowing streams (Ref. 83406).
