Tubercles on snout and lower jaw absent, 9–11 blue vertcal bars along the body, dorsal fn hyaline with dark pigment concentrated along lower two-third of the dorsal-fn rays.

INTRODUCTION & Vishwanath (2012). Colour patern was recorded from fresh and preserved (10% formalin) specimens. Fishes of the genus Barilius Hamilton Voucher specimens are deposited in the Museum of (Cyprinidae:Danioninae: Chedrini) are one of the the Zoological Survey of India (ZSI), Kolkata and at the dominant small-sized fshes occurring in hill streams ICAR-Central Inland Fisheries Research Insttute (CIFRI), and upland rivers throughout India, Bangladesh, Barrackpore. Myanmar, Nepal, Sri Lanka, China, Iraq, and Thailand (Selim & Vishwanath 2002; Jayram 2010; Tejavej 2012; Barilius torsai sp. nov. Qin et al. 2019). Barilius was erected as a subgenus (Image 1) of Cyprinus with Cyprinus barila Hamilton, as the type urn:lsid:zoobank.org:act:79FEC835-A4FA-4D27-8EC1-2EDD65616A31 (Qin et al. 2019). Howes (1980) identfed two groups within Barilius (sensu lato), corresponding to the genera Type material Barilius and Opsarius (Rainboth 1991). These bariliine Holotype: ZSI FF5542, 12.xi.2015, 26.7290N & fshes are characterised by their relatvely elongate, 89.3250E, 71.41mm SL, Torsa River, Jaldapara, Alipurduar compressed bodies with round belly, vertcal bars on the District, West Bengal, India, coll. A. Roy Chaudhary. fanks, 9–17 anal-fn rays and sub-laterally placed lateral Paratype: ZSI FF5543, 26.vii.2015, 26.7290N & line (Hamilton 1822; Howes 1980; Talwar & Jhingran 89.3250E, 74.56mm SL, data same as for holotype, coll. 1991; Tejavej 2012). Of the 36 valid species of bariliine A. Mitra; CIFRI F10003-10010, 8 ex., 26.vii.2015, 71.46– fshes, 24 have been recorded in India (Fricke et al. 74.23 mm SL, data same as for holotype, coll. A. Mitra; 2019; Qin et al. 2019). Currently, most bariliine fshes, CIFRI F10011, 12.xi.2015, 71.46mm SL, data same as for including all southeastern Asian species are assigned to holotype, coll. A. Roy Chaudhary. the genus Opsarius (Howes 1983; Rainboth 1991; Qin et al. 2019) and the genus Barilius is restricted to fve Diagnosis species characterized by an extremely shallow body: Barilius torsai is distnguished from all other species B. barila (Hamilton, 1822), B. evezardi Day, 1872, B. of Barilius by a combinaton of the following characters: modestus Day, 1872 and B. vagra (Hamilton, 1822) from lateral line complete with 52–53 scales, 29 pre-dorsal India, and B. mesopotamicus Berg, 1932 from the Tigris- scales, pectoral fn notched, two well-developed pairs Euphrates basin, based on the diagnosis of Barilius sensu of barbels (rostral and maxillary), body with 9–11 blue by Howes (1980), as well as morphological (Howes 1980; vertcal bars, dorsal fn hyaline with dark pigment 1983) and molecular phylogenetc evidence (Tang et al. concentrated along lower 2/3rd of dorsal-fn rays. 2010; Liao et al. 2011; Qin et al. 2019).
