Cladistic analysis of southern African paramelitids. Aquadulcaris gen. nov. is almost certainly most closely allied to the Aus- tralian genus Uroctena, which also includes members with 'pediform' second antennae and poorly emarginate fourth coxal plates (Williams & Barnard 1988). The unresolved nature of group B can be attributed to a combination of the relative shortage of 'good' apomorphies and the possibility that the genus, as currently composed, is not monophyletic. For example, it is possible that 'weak' synapomorphies are shared due to parallel evolution rather than due to common descent. A good example of this is the possession of medial spines on article 2 of pereopod 3, a condition shared by Paramelita granulicornis and P. capensis. Myers (1988) also expressed concern about the effect of parallel evolution on the development of a synapomorphic scheme and concluded, from his study of.
