Etymology: Schistura:Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335); sonarengaensis:Name 'sonarengaensis' from the type locality of the species, Krem (= cave) Sonarenga. A noun in apposition.
背鰭 (合計) : 12; 臀鰭: 8; 脊つい: 35 - 37. This species is distinguished from its congeners by the following set of characters: a color pattern of 13-26 vertically elongate to circular mid-lateral black blotches (brownish in life) overlayered on a grayish black mid-lateral stripe on a dull white or pale-beige (golden brown in life) body; predorsal color pattern variable consisting of discrete saddles, or combination of saddles and longitudinally elongate anterior most blotches, or two parallel longitudinal stripes, and/or a combination of each; 7-8 discrete sub-dorsal and post-dorsal saddles not contiguous with the mid-lateral stripe, except the posterior most saddle sometimes reaching the stripe; and a short vertical black bar medially occupying the caudal-fin base; dorsal-fin origin nearly opposite to pelvic-fin origin; complete lateral line; short, shallow adipose crest on dorsal and ventral midlines of caudal peduncle; moderately forked caudal fin; axillary pelvic lobe present; prominent processus dentiformes on upper jaw; the chest naked; 9-8 + 8 caudal-fin branched rays; 8½ branched dorsal-fin rays; and no discernible sexual dimorphism (Ref. 137714). Body shape (shape guide): elongated; Cross section: oval.
This species inhabits a small, stagnant muddy pool measuring approximately 0.5 × 0.8 m2 and about 0.7 m deep, situated roughly 700 m from the main entrance. The substrate of the pool consists predominantly of sand interspersed with scattered pebbles (Ref. 137714).
