Heterophoxus ophthalmicus (Schellenberg) 



Harpinia ophthalmica Schellenberg 1925: 136-138. 

 Heterophoxus ophthalmicus, J. L. Barnard 1958: 148. 



Remarks. — In looking over Schellenberg's rather good description 

 it is at once apparent that he had an heterophoxid. This is shown by 

 the presence of eyes, the ensiform process on the second antenna and 

 the short fourth palp article bearing a long seta on the maxilliped. 

 Because figures were not given, it is quite difficult to distinguish this 

 species either from H. trichosus or H. oculatus. Schellenberg distin- 

 guished his species from Harpinia oculata Holmes (=Heterophoxus) 

 by the larger expanded second article of peraeopod 5, the broad posterior 

 teeth of that appendage, and the paucity of setae on the antennae, coxae 

 and third pleonal epimeron. The setation in Holmes' figures and descrip- 

 tion is not typical of the species in general, for it is a rather large and 

 setose specimen, so that this difference would not be of great use in dis- 

 tinguishing the species. Only in the large and broad teeth of H. ophthal- 

 micus can any difference be found. 



Distribution. — Nigeria, Lagos. 



Heterophoxus trichosus K. H. Barnard 



Heterophoxus trichosus K. H. Barnard 1932: 100-101, fig. 50; Stephen- 



ensen 1947: 38. 



Diagnosis. — Third pleonal epimeron with a very long tooth; peraeo- 

 pod 5, article 2 reaching to middle of fourth article, posterior teeth 

 acute, lower edge anteriorly concave, appearing subacute, whereas in 

 other heterophoxids the lower edge is convex. 



Remarks. — A number of important generic and specific points need 

 to be described for this species in order to verify that it is an hetero- 

 phoxid. Particularly needed is a description of the third uropods, whether 

 the second article of the outer ramus is minute. 



Distribution. — South Shetlands and Graham Region, 200 m.
