Saffi 2, 61029, Urbino (PU), Italy (E-mail: micros.naturae@gmail.com) Abstract A new name, Onthophagus froggattellus Monteith & Rossini, nom. nov. is proposed for the preoccupied Onthophagus bicornis Macleay, 1888 and its type specimens and type locality near King Sound, NW Australia, are clarified. It occurs in a number of disjunct distributional foci across tropical Australia and specialises on dung of the fungus-feeding northern bettong, Bettongia tropica Wakefield, in part of its range. Introduction In 1887, the wealthy Sydney patron of natural history, William John Macleay, engaged the 28 years old Walter Wilson Froggatt to go for a year to the newly settled town of Derby, at the foot of King Sound on the remote NW Kimberley Coast of Australia, to collect specimens for his private Macleay Museum. Froggatt was an experienced and bold collector who had already been on the Royal Geographical Society of Australasia (NSW) 1885 New Guinea Expedition (Fig. 1) and had been employed previously by Macleay to collect in north Queensland in 1886 (Froggatt 1935). Froggatt was at King Sound from April 14, 1887 to February 22, 1888 (Froggatt 1934). Macleay exhibited some of Froggatt’s advance collection at meetings of the Linnean Society of NSW in late 1887 before Froggatt himself returned to Sydney (Macleay 1888a). Soon after Froggatt’s return, Macleay published a paper, in 3 parts, entitled ‘The Insects of King’s Sound and its vicinity’, describing 183 new species of Coleoptera from the material (Macleay 1888b, c, d), including 17 dung beetles. One of these, described on p. 901 of the second part, is a small brown dung beetle he called Onthophagus bicornis Macleay, 1888. As with all the species in these papers, he made no mention of particular specimens and did not designate types in the text, but his description of O. bicornis makes it clear that he had at least one male and one female before him. William Macleay, at that time, was elderly and in poor health. The curating and labelling of his specimens would have been done by George Masters, an experienced entomologist whom Macleay had lured from employment at the Australian Museum in 1874 to be curator of his private museum. In the same year that he published on those King Sound collections (1888), Macleay gifted his whole private museum to the University of Sydney and gave funds for it to employ George Masters to curate the collection until Masters’ death (Strahan 1979). Macleay died three years later and George Masters lived until
