Raggi dorsali molli (totale) : 7; Raggi anali molli: 11 - 12; Vertebre: 37 - 39. Excluding Pseudecheneis paviei, Pseudecheneis sulcatoides, and Pseudecheneis sympelvica, this species differs from other all congeners by the absence of a prominent bony spur on the anterodorsal surface of the first dorsal-fin pterygiophore. Can be separated from these three species by the combination of the following characters: body elongate with 36-39 vertebrae; thoracic adhesive apparatus with 12-14 transverse laminae; separate pelvic fin; caudal peduncle length 25.0-28.3% SL; presence of a first-dorsal element; complex vertebra with bifid neural spines. Additional characters useful to distinguish this species include: caudal-peduncle depth 4.0-5.2% SL; eye diameter 8.8-10.6% HL; pelvic-fin length 21.2-28.7% SL; length of adipose-fin base 17.8-22.7%; body with pale colored patches; neural spines of the last 2-3 preanal and first 6-7 postanal vertebrae gradually increasing in height; pectoral fin length 121.6-156.3% HL; and vertebrae 37 (Ref. 74729).
Body shape (shape guide): elongated.
Found in fast-flowing hill streams. Prefers deep riffles and runs over gravel, cobble substrates (Ref. 12045).
