344 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 18 



Proharpiniid sp. 



Harpinia obtusifrons, Chilton 1909: 619 (in part) ; Chilton 1912: 477- 

 478 (not Stebbing 1888). 



Remarks. — Some of the materials referred to in the above references 

 have not been clearly identified, although reference is made to harpiniids 

 with eyes, referable to Proharpinia or Heterophoxus. 



Localities. — New Zealand: Lyttelton Harbour and Bay of Islands; 

 South Orkneys: Scotia Bay Station 325. 



Genus Harpinia Boeck 



Harpinia Boeck 1876: 218; Sars 1895:150; Stebbing 1906: 140. 



Diagnosis. — Maxilliped palp article 4 with 2 or 3 long apical setae; 

 eyes absent; article 2 of peraeopod 3 narrow; male and female second 

 antennae short; male antennae of both pairs armed with large brushes 

 of setae on basal articles. 



Type species. — Phoxus plumosus Kroyer. 



Remarks. — This genus is unusual in the Phoxocephalidae for the 

 short second antennae of the male and the development of setal brushes 

 on both pairs of male antennae. Only a few males of the numerous 

 species are known and for this reason not all of the species based on 

 females can be placed firmly in Harpinia. Species of the genera Harpin- 

 iopsis and Pseudharpinia have been or can be placed in or confused with 

 Harpinia. 



It is a debatable procedure whether to base the genus Harpiniopsis 

 on a secondary sexual character such as elongated second male antennae 

 but the systematic concept has value for morphological and zoogeo- 

 graphic purposes until complete pictures of all the species can be 

 assembled (Barnard 1958). For these reasons I have restricted all 

 harpiniids with elongated male antennae in the genus Harpiniopsis 

 resulting in a body of species from the eastern Pacific Ocean and one 

 from the North Atlantic Ocean, with possible zoogeographic implica- 

 tions (Barnard 1958). The males of many species from the Atlantic 

 Ocean, North Pacific Ocean and other seas are unknown and are 

 provisionally relegated to Harpinia. 



Because of the confusion in these matters it has been necessary to 

 construct a key which includes females of Harpinia, Harpiniopsis and 

 Pseudharpinia, which follows.
