(Le Souef, 1924)
|Purple-necked rock-wallaby range|
The purple-necked rock-wallaby (Petrogale purpureicollis) was first classified in 1924 by Albert Sherbourne Le Souef, then director of the Taronga Zoo in Sydney, Australia, who noted a strange purple colouration around the neck as well as skull differences separating it from other rock-wallaby species. The species has undergone taxonomic upheaval for decades and has variously been classified as an unadorned rock-wallaby, brush-tailed rock-wallaby, and black-flanked rock-wallaby. Le Souef and others have asserted that it was a new species, and this has been affirmed by a 2001 paper in the Australian Journal of Zoology.
The purple colouration was thought by some sceptical scientists to be due to the animal rubbing against a dye, but the animal does in fact secrete the purple pigment. The pigment is known to wash off in the rain and fade away after death, causing some possible confusion with other rock-wallaby species.
