Barbonymus: from the generic name Barbus, to which members of this genus were previously assigned, and Ancient Greek ἀνώνυμος (anṓnumos), meaning ‘anonymous’, since this group of fishes had previously lacked a proper generic name.

Gonionotus: from the Ancient Greek γωνία (gōnía), meaning ‘angle’, and νῶτον (nōton), meaning ‘back’, in reference to this species arched lateral profile.

Classification

This‚ species‚ is currently accepted to have an enormous distribution that covers much of Southeast Asia including Cambodia, Laos, Thailand, Vietnam, Singapore, and Indonesia (Java and Sumatra). It is present in several major‚ river‚ systems including the Mekong, Mae Klong, and Chao Phraya, and appears to have been introduced to the Terengganu and Perak river systems in Peninsular Malaysia.

Type locality is ‘Indonesia: Java: Kalimas River [Brantas] in Surabaya’.
