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
).
