oa African Entomology - Katacamilla Papp, 1978, a genus of Camillidae (Diptera: Schizophora) associated with the dung of bats, birds and hyraxes in Africa and the Arabian Peninsula
Katacamilla Papp, 1978, hitherto a monotypic genus of Camillidae known only from Namibia, is revised to include five species from Africa and the southern part of the Arabian Peninsula. The revision is based on more than 400 specimens. The placement of Katacamilla in the Camillidae is confirmed. A revised diagnosis of the genus is given. Katacamilla is distinguished from all other camillid genera by at least 10 character states, six of which are autapomorphies. A key to the species is presented. illustrations of head profiles, male forefemur and terminalia are provided for all species. Katacamilla cavernicola Papp is redescriptionbed from three Namibian localities. Four new species are descriptionbed: K. braacki from northeastern South Africa, K. ctenidia from northern Nigeria, K. gallagheri from eastern Oman and K. procavia from central Namibia. Katacamilla cavernicola is known only from caves, where it exhibits both parietal and troglophilic habitat preferences; it has been reared from dung of the rock pigeon, Columba guinea Linnaeus (parietal), and of the common slit-faced bat, Nycteris thebaica Geoffroy (troglophilic). Katacamilla braacki has been collected in close association with dung of the Egyptian fruit bat, Rousettus aegyptiacus (Geoffroy), in a troglophilic habitat. Katacamilla procavia has been reared from the dung of the rock hyrax, Procavia capensis (Pallas), taken from the shelter of a rocky overhang. Katacamilla ctenidia and K. gallagheri are probably associated with the dung of birds and/or small mammals in relatively exposed habitats. A preliminary cladistic analysis suggests that the clade comprising the bat-associated (cavernicolous) sister species, K. cavernicola and K. braacki, is the most highly derived in the genus and, consequently, that association with bats is a recent specialization.
