While surveying dung beetles in Zambia and Mozambique, we found a series of specimens that key out to Onitis lycophron Klug, 1855 in the
The main purpose of describing this new species of Onitis is to make the name available for a field guide of the dung beetle species of Parque Nacional das Quirimbas (FG, in preparation). Although the taxonomy of the species belonging to group 19 needs to be reviewed, the uniquely shaped parameres unambiguously separate this undescribed taxon from all others in the genus.

While visiting the Royal Belgian Institute of Natural Sciences in Brussels, we found a specimen of this species bearing the “Onitis collarti” paratype label of André Janssens. Since Janssens’ name was never formally described we decided to honour this homage with the modification to “O. albertcollarti”. Albert DCH Collart was a colleague and friend of André Janssens a well-known scarab worker. Collart first worked as a sanitary agent in the former Belgian Congo from 1923 to 1930. For health reason he had to come back to Belgium and started to work as a scientific collaborator for the entomology department of the former Royal Museum of Natural History in 1932. He was promoted several times and concluded his career as the Laboratory Director of the Institution in 1964. He retired in January 1965 and remained associated as a scientific collaborator of the Royal Belgian Institute of Natural Sciences until his death in 1993.
From southern Democratic Republic of the Congo (Katanga) to Tanzania in the north and eastern Zambia through northern Mozambique in the south. Onitis albertcollarti occurs sympatrically with O. lycophron on most of its northern distribution.
Specimens with data were collected using pitfall traps baited with human faeces and elephant dung and were attracted to light traps. Some individuals were collected in eastern Miombo woodlands and central Zambezian woodlands.

The senior author wishes to thank Mark Hoekstra, Luis Augusto, Marcelino Denja, and the park warden José Dias dos Santos Mohamede, who greatly facilitated the fieldwork in Parque Nacional das Quirimbas (Cobo Delgado, Mozambique), where specimens of the new species were collected. Alain Drumont (IRSNB), Jean-François Josso, and Robert Minetti contributed the bulk of the studied specimens. Andrew Smith kindly reviewed the manuscript and greatly improved the final version. A special thanks to Francine and Robert K. Barrett for their ongoing support of scarab taxonomy and systematics.
