Remarks. Eunice afra has been widely reported from warm water areas; the type, from Mozambique was redescribed by Fauchald (1992). It is uncertain how much of the material previously reported from the Pacific and Indian Oceans, including the coasts of Australia, belong to this species. Specimens in the collections of the Australian Museum agree with E. afra (sensu Fauchald 1992) in having dark bidentate subacicular hooks and branchiae starting posterior to chaetiger 10. All specimens examined have short, irregularly articulated antennae and palps. However, the variability, especially in the first occurrence of branchiae and subacicular hooks in similarly sized specimens is so high that it is likely that more than one species is present. According to our observations, none of them agree fully with the holotype of E. afra. Resolution of the problems related to this species will depend on a careful study of a large amount of circumtropical material and is well beyond the scope of this study. Day (1975: 194) reported both E. afra and E. afra paupera Grube, 1878 present in material from Western Australia. He had available only juveniles with single branchial filaments and would not have been able to separate the two, which traditionally have been separated only on the number of branchial filaments present. Eunice paupera is here considered a distinct species differing from E. afra in adult chaetal characters as well as in the structure of the branchiae (see Fauchald 1992).
Type locality. Ibo, Mozambique.
