It is widespread in the Afrotropical Region: Ethiopia, Kenya, Mauritania, Tanzaniaand Zaire( Smith & Vockeroth, 1980; Whittington 2003) and Yemen( Smit et al. 2017).  Genus  CerianaRafinesque   Cerianacontains 55 species and is found in all regions except the Neotropics ( Thompson 2013). Ricarte et al.(2007b)described and compared the puparia of 10 species of the tribe Cerioidini: three species of  Monoceromyia, two species of  CerianaRafinesque; four species of  PolybiomyiaShanon; and one species of  SphiximorphaRondani. Theyfound that all the species studied possessed the diagnostic characters for the tribe but there is no correlation of characters in early stages. They concluded that early stages did not form groupsbased on shared characters. They reared the larvae of these species from tree sap, tree holes, the liquid centre of a cut agave ( Agavaceae) and bee nests ( Hymenoptera: Apidae). From their field observations of larvae and their breeding site they suggested that there are functional explanations for some morphological features. 3029038337 [420,1319,326,352] 1981-11-19 KSMA A.
