Etymology: Schistura: Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335); kengtungensis: Named for Keng Tung, a town close to the type locality.

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 11.0 cm SL male/unsexed; (Ref. 12693)
Dorsal soft rays (total): 12; Anal soft rays: 8. A member of the group of species with complete or nearly complete lateral line, 8 1/2 branched dorsal rays, 9+8 branched caudal rays and no sexual dimorphism. Can be distinguished by the following characters: caudal peduncle 1.10-1.44 times longer than deep, its length being 14.2-17.5% SL, 67-86% HL and its depth 11.5-13.2%SL, 52-62% HL; 8-11 bars; black basal caudal bar not reaching dorsal and ventral midlines, moderate keels on caudal peduncle, a median interruption in lower lip. Caudal fin emarginate (Ref. 39226). With slight depression at nape; 8-12 bars that turn into blotches on lateral line and saddle-markings dorsally; scales lacking on belly and on back between head and dorsal fin (Ref. 12693). Dorsal fin base with a black spot anteriorly, followed by an orange patch and a low elongate grey blotch (Ref. 43281).
Inhabit small, shallow, high gradient streams with cobble or boulder substrates (Ref. 12693). A ripe female measuring 5.27 cm SL with ovulae 2.4 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 (0.00310 - 0.01545), 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.
59153): Low vulnerability (10 of 100).
