Description of Callophyllamacrocephala sp. n. from southern Tanzania

A male cetoniine specimen from the old Schürhoff collection currently deposited in the Ditsong National Museum of Natural History (Pretoria, South Africa), was recently submitted for identification and has been found to represent a yet undescribed species of the poorly-known genus Callophylla Moser, 1916. The species is named C.macrocephala sp. n., in recognition of its wider than average head, particularly at the level of the clypeus, and originates from the southern Tanzanian highlands, near the Tanzania-Zambia border town of Nakonde. This brings the total number of species now known for this genus to four, two from West Africa and two from East-Central Africa. All species were described on the basis of a male only, or this and a few extra specimens. The female is only known for the two West African species, C.costata Moser, 1916 and C.lamottei Antoine, 2007. A dichotomous key for the identification of the species of this genus is presented for the first time. It is suggested that the genus may be constituted of high altitude specialists, with a short period of activity and no ability to feed at the adult stage.
