Etymology: Schistura: Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335).
More on author: Smith.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical
Asia: Chao Phraya in Thailand (Ref. 12041), Mekong basin in Laos and Thailand, northern Mae Nam Ping basin in Thailand and Salween basin in Thailand and Myanmar (Ref. 43281).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.9 cm SL male/unsexed; (Ref. 39226)
Dorsal soft rays (total): 12; Anal soft rays: 8. Distinguished by its color pattern: the bars in front of dorsal fin are conspicuously thinner than those behind, usually united in pairs (or more) at their upper extremity. This color pattern is shared with a few other species in area; S. poculi is distinguished from S. vinciguerrae by 8+7 branched caudal rays (versus 9+8), from S. mahnerti and S. bella by the absence of sexual dimorphism (both species have a well developed suborbital flap in males ) and by details of the color pattern (Ref. 39226).
Body shape (shape guide): elongated.
Occurs in brooks and streams with swift current, among large pebbles, stones and boulders (Ref. 39226). Found in creeks and streams with moderate current and clear water (Ref. 43281). A 4.82 cm SL female contained nearly ripe ovulae, about 1.3 m diameter; when collected, a 5.22 cm SL female extruded yellow-orange ovulae; one of them still adheres to its genital opening (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).
