Short description
Dorsal soft rays (total): 7; Anal soft rays: 11 - 12; Vertebrae: 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). Description: D i+6; A iii,8, iv,7, iv,8; P i+12, i+13; V i+5 (Ref. 57830).
Biology
Found in fast-flowing hill streams. Prefers deep riffles and runs over gravel, cobble substrates (Ref. 12045).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00264 - 0.01315), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.2 ±0.4 se; Based on size and trophs of closest relatives.
Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing vulnerability (Ref. 59153): Low vulnerability (10 of 100).
Nutrients (Ref. 124155): Calcium = 0 [0, 0] mg/100g; Iron = 0 [0, 0] mg/100g; Protein = 0 [0, 0] %; Omega3 = 0 [0, 0] g/100g; Selenium = 0 [0, 0] μg/100g; VitaminA = 0 [0, 0] μg/100g; Zinc = 0 [0, 0] mg/100g (wet weight);
