Etymology: xyrops: The specific name is derived from the combined Greek xyron (χυρον), razor, and ops (ωψ), eye, in reference to the sharp, exposed bony margin of the supraorbital and the wide infraorbital process. A noun in apposition. More on authors: Fang & Kullander.

Morphology | Morphometrics
soft rays: 17 - 19;
Vertebrae: 34 - 35. Diagnosed from all congeners except Devario anomalus by its the color pattern, with a dark blotch anteriorly on the side composed of 4-5 short partly confluent vertical bars which may also be confluent to form a homogeneous blotch, and a wide dark horizontal band (P stripe) posteriorly on the side. Differs from Devario anomalus by proportional measurements and meristics, most important by deeper body (29.9-35.,8% SL, vs. 25.0-26.8 % SL) and fewer lateral line scales (31-33, modally 32 vs. 33-35, modally 34). In addition, the presence of an infraorbital process separates this species from all barred species of Devario (Ref. 81819).
The type locality is a small forest river with clear, colorless and slow-flowing or stagnant water and with bottom made up of stones, gravel and rock (Ref. 81819). During low water season, this forest river is reduced to a series of connected pools, up to 2 m wide, and not more than 1 m deep (Ref. 81819).
