Abstract

The world fauna of Ctenostylidae is briefly reviewed and placement of the family in Tephritoidea discussed; southern African Ctenostylidae are characterised relative to other acalyptrate families. Exclusion of Ctenostylidae from Pyrgotidae is confirmed. Probable plesiomorphic features of Ctenostylidae relative to the ground plan of Tephritoidea are discussed. The Afrotropical Region has only two known species of Ctenotylidae, one from Madagascar (Ramuliseta madagascariensis Hennig, 1960) and the other from southern and east Africa (R. lindneri Keiser, 1952). A key to these species is presented, and lindneri is redescriptionbed on all available material. The first-instar larva of lindneri is descriptionbed and compared to those known for Ctenostylidae and Pyrgotidae; both Afrotropical species of Ramuliseta appear to be larviparous. The first-instar of lindneri differs markedly from that of Pyrgotidae in having well-developed mouthhooks and nine anteroventral bands of short spinules. No males of Lindneri are known, and it is suggested that this species and congeners may reproduce parthenogenetically.
