Melobasis rothei  Distinctive features

Grey-bronze to coppery colouration with fine appressed hairs on the ventral surface, legs, frons and anterior margins of pronotum. In the protologue, Blackburn 1887 drew attention to the prosternum being depressed towards its anterior margin.

Notes

Named by Blackburn 1887 after a Mr. Rothe of Sedan (in the MU Region against the eastern margin of the Mt Lofty Ranges) from whom he received a collection of this species.

Adults are appear to be specifically associated with Senna and their appearance coincides with the flowering time of these bushes.
