(Synhelea) tropicalis Kieffer are described and illustrated for the first time, and the pupa of C. similis Carter, Ingram & Macfie is redescribed. All seven species belong to the Similis supergroup; the immature stages of six are found in ground waters while those of C. olyslageri occur in tree holes. A concise key is presented for differentiating the seven species. Short notes on their larval habitats are given. Reference is made to C. accraensis Carter, Ingram & Macfie, also found in tree holes. Available data suggest that pupal morphology can be used to differentiate closely related species; group characters also exist for those species within the Similis supergroup which can be used to separate ground-water species from those utilizing tree holes. Indications are that the pupae are of limited help in resolving the systematic subdivision of the Similis supergroup.en© ARC-Onderstepoort (original). © University of Pretoria.
