Etymology: Dario: Bengali/Bangla: ‘Darhi’, local Bengali name for this species; ‘Darhi’ also means ‘beard' (Ref. 2031); urops: The specific name is derived from the Greek ουρά, ta meaning tail, and ὄψ, , meaning eye. This is in reference to the conspicuous eye spot on the caudal peduncle. A noun in apposition.

Morphology | Morphometrics
(total): 14 - 15;
soft rays: 8 - 9;
Vertebrae: 28 - 29. Distinguished from all its congeners by having conspicuous black caudal blotch on the caudal peduncle (vs. absence), by having a horizontal suborbital stripe (vs. absence), by the anterior dorsal fin lappets in males not extending beyond fin spines (vs. extending considerably
beyond spines), and by its vertebral count (14+14-15= 28-29 vs 11-13+12-14=24-27). Differs further from Dario dario and Dario hysginon by the absence in males of a dark stripe along the anterior margin of the pelvic fin, and from Dario dario by the absence of bars in males (Ref. 90259).
Found in a small clear water stream, up to 10 m wide and 2 m deep, with a bottom formed of a mixture of sand and mud and larger boulders. Occurs mostly from among bundles of tree roots hanging into the water along the edges of the stream and from thicker layers of leaf litter that had accumulated in low current depressions of the stream (Ref. 90259).
