Abstract

The carob gall midge, previously known as Eumarchalia gennadii (Marchal), is formally assigned to Asphondylia H. Loew, and Eumarchalia Del Guercio is synonymised with Asphondylia. Specimens of Asphondylia reared from pod galls on carob (Ceratonia siliqua) during biological research by G. M. Orphanides in Cyprus seem to be morphologically indistinguishable from specimens reared by him from galls on Capsicum annuum, Capparis spinosa, Urginea maritima, Asphodelus fistulosus, Solanum tuberosum, Hypericum crispum and Sinapis spp. Possible reasons for this unusually wide host range of the carob midge are discussed with particular reference to the occurrence of ambrosia fungi in galls of the genus Asphondylia. Gall midges reared from Verbascum sinuatum in Cyprus are morphologically distinct from A. gennadii and are identified as A. verbasci (Vallot). Characters separating these two species are illustrated and tabulated.
