oa Annals of the Natal Museum - The southern African species of Neriidae (Diptera)

Volume 34, Issue 1
  • ISSN : 0304-0798



The southern African Neriidae are characterised relative to other acalyptrate families and distinguished from the Micropezidae, the only other family of Nerioidea represented in the subregion. The Afrotropical fauna of Neriidae is discussed and Chaetonerius Hendel, 1903 (the only African genus) is distinguished from Oriental and Australasian genera of Telostylinae. The biology, behaviour and distribution of Chaetonerius species in southern Africa are discussed; two species have been reared from (decaying) pumpkin (Cucurbita pepo L.). Four species of Chaetonerius are recorded from the subregion, two of which are descriptionbed as new. An annotated species key is provided. The southern African species of Neriidae are: C. apicalis (Walker, 1849), C. londti sp. n., C. nolae sp. n. and C. perstriatus (Speiser, 1910). The male postabdomen is descriptionbed for each species and although C. apicalis and C. perstriatus are not redescriptionbed, intraspecific variation is reviewed.
