Holotype : AMS IA.39. Type locality: Clarence River Estuary, New South Wales , Australia . Local synonymy: Himantura (?) gerrardi— Filewood, 1973 : 12 (PNG).

Remarks: First recorded from PNG by Filewood (1973) as Himantura (?) gerrardi ; the characters provided in Filewood’s key includes “colour pattern of few pale-centred spots far apart, sometimes also irregular white splashes, tail usually strikingly banded” which matches the adult colour pattern of M. toshi . Possibly conspecific with M. astra . Appears to be more restricted to inshore muddy areas. Previously placed in the genus Himantura .
