Description from Gosavi et al. (2017)

The genus Leucisca was erected by MacLeay for the South African species, Leucisca squalina, until a second species from Australia, L. levigena, was described for the genus (George & Clark, 1976). Along its distribution range, Natal specimens are smaller than Cape specimens, but otherwise indistinguishable (Barnard, 1946).
