“…Rainboth (1991) proposed that the majority of Barilius species, including all Southeast Asian species, be placed in the genus Opsarius (Howes, 1983; Qin et al, 2019). Currently, the genus Opsarius has 29 recognized species, distinguished by its elongated and compressed body with round bellies, vertical bars on the flanks, 9–17 anal fin rays, and a sub‐laterally positioned lateral line (Arunkumar & Moyon, 2017; Barman et al, 2011; Howes, 1980; Kottelat, 2013; Talwar & Jhingran, 1991).…”
