Melanterius sp. near M. semiporcatus In the ANIC there are eight specimens of an undescribed species from Western Australia, similar to M. semiporcatus (in fact interpreted as the same species by E. C. Zimmerman in his manuscript on Melanterius) but differing in a smaller size, more regularly punctate pronotum, the presence of minute punctures on the interstices between the elytral punctures, two larger oblique setal fields on the metaventrite and, most clearly, the shape of the penis (short and broad, with a pair of small simple basal endophallic sclerites but the endophallus densely spinulose). Five of the specimens in the ANIC are labelled as having been collected on Regelia, a small, endemic Western- Australian genus of Myrtaceae, but the species is unlikely to breed on this plant genus. We did not collect any specimens of it.
