Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical
Asia: known from high altitudes in the Rivers Ko and Tan in Annam, Viet Nam. Has not been rediscovered since the collection of the types in 1936.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.7 cm SL male/unsexed; (Ref. 40772)
Dorsal soft rays (total): 12; Anal soft rays: 8. Can be distinguished from any other nemacheiline by the presence of a strong processus dentiformis on both jaws and by anterior nostril pierced in front side of a pointed tube (Ref. 40772).
This species was collected from the upland streams (Ref. 117882). The ovaries of a 6 cm SL female contain ovulae about 0.8 mm in diameter (Ref. 39226).

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=0.00692 (0.00311 - 0.01538), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.3 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.
