Etymology: Schistura: Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335); udomritthiruji: Named for Kamphol Udomritthiruj.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 8.0 - ?; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 29°C - ? (Ref. 83421)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.8 cm SL male/unsexed; (Ref. 83421)
Morphology | Morphometrics
soft rays: 8. Differs from congeners by the combination of the following characters: caudal fin with 9+8 branched rays; males possess suborbital flap (absent in females); lateral line ends above base of anal fin; caudal fin hyaline; and bars on posterior half of body more than twice as wide as interspaces (Ref. 83421).
At the time of sampling, the type locality was a stream with width up to 8 m, but the riverbed would allow a 20 m wide river at high water level, and with calm stretches, depression up to 1 m deep as well as riffles. Riffle consisted of gravel with few larger stones and maximum water depth of 40 cm (Ref. 83421).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00270 - 0.01543), b=3.00 (2.83 - 3.17), 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
Vulnerability (Ref. 59153
