tenna 3-segmented, with clawlike terminal process and frequently, 

 in male, with adhesion or additional spinelike process. Mandible 

 rodlike, distal region flattened, with 12 denticulations on distal inner 

 sm-face. Postantennal process consisting of 3 nodules, each with 

 several hairlike processes, and clawlike projection; postoral process 

 spinelike, often with smaller, spinelike secondary projection on inner 

 surface in male. MaxUlule nodular, with setule-like processes; 

 maxilla 2-segmented, with 2 saber-like terminal processes. Sternal 

 fiu-ca present. Thoracic legs I-III biramous although endopodite of 

 first legs rudimentary; fourth legs uniramous, typically with 4

Distribution and hosts. — 4 host records: 



locality hosts reference 



Western Atlantic Rhombochirus osteochir V/ilson and Bere, 1936 



Eastern Pacific "Remora" 



Remilegia australis Shiino, 1963a 



Indian Ocean Echeneis albescens Shiino, 1960c 



Material. — Five females (USNM 112884) from external siu-face 

 of Rhombochirus osteochir (Cuvier) taken from Tetrapturus angusti- 

 rostris Tanaka captm-ed by longline at 21°04.5'N, 173°47.5'E (USF 

 WS). Two females and 1 male (USNM 112885) from external siu-- 

 isice oi Rhombochirus osteochir (Cuvier) taken at20°50.5'N, 167°34.5'E. 



Remarks. — Although these specimens were taken well west of the 

 Hawaiian Islands, the hosts are found in the Hawaiian area. Based 

 upon this and the wide reported distribution of the copepod, the author 

 feels that the copepod is a member of the Hawaiian parasitic copepod 

 fauna.
