Melobasis rothei Distinctive features
Bronze to dark grey-bronze colouration and a broad, thick body shape. Head with a shallow depression medially at the junction of the anterior frons and clypeus, a feature unique within the species group (Levey 2023). Readily distinguishable from M. sordida by the puncta of the medial pronotum not being transversely elongated, and from M. soror soror by the rather weak elytral costae.
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.
In the protologue, Blackburn 1887 commented that "the peculiar form of the thorax distinguishes this insect from all other species that bear any resemblance to it" and drew attention to "the prosternum a little elevated across its front margin instead of being declivous". These features are difficult to interpret.
Until November 2020 Melobasis rothei was included on these pages within the entity Melobasis sp. Brown. I am grateful to Brian Levey (2020, pers. comm.) who identified the images shown here as being M. rothei, having previously seen the type and matched specimens of this species against it.

Host plant notes
Levey 2023 reports adults that adults have been collected from foliage of Senna and Acacia species. My collections in SA have all been from Senna artemisioides.
