The specific name refers to the rectangular shape of the black subdorsal blotch of the species. A noun in apposition..

Chaves de identificação | Morfologia | Morfometria
Raios dorsais moles (total) : 8; Raios anais moles: 7; Vértebras: 32 - 33. Diagnosed from other species of Rasbora by the following combination of characters: supra-anal pigmentation absent; the black midlateral stripe is only represented by a rectangular subdorsal blotch without a midhumeral diffuse patch and the posterior-portion stripe; and the basicaudal blotch appearing somewhat oval and lacking the basicaudal triangular patch (Ref. 94947).
