Pethia striata Atkore, Knight, Rema Devi & Krishnaswamy 2015

Pethia striata can be diagnosed from other species of the genus Pethia by the combination of the following characters: lateral line complete, with 20-21 pored scales up to tail fin base; upper half of body dark brown; outer edges of body scales dark, forming oblique bars, giving a distinct striped pattern along the side in both sexes; dorsal fin dark with a pale outer margin; dorsal, pectoral, pelvic, and anal fins tinged with black; caudal fin hyaline; black humeral spot one scale below the 4th lateral-line scales, a larger black blotch 3-4 scales high covering the 17th to 19th lateral-line scales, and only 2 scales between this blotch and the hypural notch. Other characters useful to distinguish from other congeners include the following: fewer transverse scales, 3 scales between lateral-line scale row and ventral fin; ½ 4+1+3 transverse scales; eight predorsal scales; a smaller humeral spot, restricted to a single scale; lacking a gray patch below the dorsal fin; two spots, a humeral spot and a caudal-peduncle blotch; 2+3-4 gill rakers on the first gill arch; a single blotch on the caudal peduncle; dark longitudinal band absent; and dorsal fin ofmale is black (Ref. 104010).

Dorsal soft rays (total): 9; Analsoft rays: 8

Formed small groups of three or four individuals in shallow pools beneath dense riparian canopy. Usually found together with other cyprinid species such as Puntius sahyadriensis and Dawkinsia arulius. A few juveniles were also observed with Pethia setnai in shallow pools (Ref. 104010).The type locality was a pool-riffle sequence in a small gently flowing clear water stream with a pH of 6.1 and water temperature of 25.5°C. The stream at the type locality has a width of 7 m and a depth of 0.6 m. The run-riffle sequence just below the type locality has a flow velocity of 0.2 m/s. This species was collected in an altitude range between 660-910 m ASL. Ochlandra sp., Ficus sp., and Elaeocarpus tuberculatus dominated the land vegetation, providing 80% shade. The substrate was composed of leaf litter mostly with Lagenandra sp., bamboo leaves, and clay. Other fishes commonly found at the type locality included the following: Devario malabaricus, Salmophasia boopis, Garra mullya, Barilius canarensis, Barbodes wynaadensis, Tor khudree, Dawkinsia arulius, Puntius sahyadriensis, Osteochilus nashii (Cyprinidae), Batasio sharavatiensis (Bagridae), and Nemacheilus denisoni (Nemacheilidae) (Ref. 104010).

Pethia striata is a species of cyprinid fish found in the Tunga River basin in Karnataka, India. This species can reach a length of 3.3 centimetres (1.3 in) SL.
