Devario coxi is similar to D. aequipinnatus in color pattern, with distinct P+1, P and P

stripes along the side, but P and P-1 stipes confluent anteriorly and containing light spots (vs.

integer to close to pectoral girdle, and interstripe I integer except occasional interruption anteriorly).

It differs from D. aequipinnatus by the combination of having more branched dorsal- fin rays (11½±12½ vs. 9½±10½, exceptionally 11½), more circumpeduncular scales (14, vs. 12, rarely 14); slightly deeper body (body depth 29.9±33.2 vs. 26.7±30.8% SL), and shorter upper jaw (upper jaw length 8.3±9.3 vs. 9.2±12.0% (SL). It is distinguished further from striped species of Devario in southern and south-western India, D. fraseri, D. malabaricus, D. mysoricus, and D. neilgherriensis by having infraorbital process vs. absent (Ref. 116720).
