簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 10; 臀鰭軟條: 7. Can be differentiated from all its congeners by the following characters: oral sucking disc large with posterior edge reaching vertical of anterior margin of eye; snout with small tubercles; body depth more than 17.2% SL; mid-ventral region anterior to pelvic-fin insertion scaleless; snout rounded, not projected; prepectoral length 16.3-18.3% SL; interorbital width 52.5-60.9% HL; head length 17.5-20.6% SL; head depth 13.2-14.2% SL; anus to anal-fin origin distance 25% posterior end of pelvic-fin base to anal-fin origin distance (Ref. 75176).
Prefers to inhabit fast-flowing water of limpid streams with cobble substrate. Reported by local people to feed mainly on algae and occasionally on aquatic plants and larvae of aquatic insects (Ref. 75176).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
