NO. 3570 PANDARIDAE — CRESSEY 23 



1 -segmented and with dorsal plate. Dorsal plate small, extending 

 only slightly beyond posterior border of abdomen (see fig. 110). 

 Caudal ramus (fig. 110) long (1.8 mm) and well exposed dorsally. 



Oral ai'ea as in other members of genus. First antenna (fig. Ill) 

 2-segmented, bearing 22 spines on first segment and 10 naked setae 

 on second segment. Second antenna (fig. 112) with tip produced into 

 a short claw similar to that of P. hicolor. Fhst maxilla (fig. 113) with 

 group of short spines on basal thhd composed of only 2 spines rather 

 than usual 3. Second maxilla (fig. 112) with distal setae in form of 

 fringed claw. 



Legs 1-4 (figs. 115-118) biramose and with spine and setal formula 

 as follows :

Leg 5 (see fig. 110) with an inner lobe and an outer long seta. 



Color dark brown except where unpigmented. Eye spots separated 

 in older females. 



Male. — 'Unknown. Kirtesinghe (1950) illustrates and briefly de- 

 scribes an immature male but not enough is shown to be of value in 

 an analysis of the adult. 



Remarks. — So far this copepod has not been reported from areas 

 other than Ceylon and Formosa. It may well be a parasite restricted 

 to the Indian Ocean and western Pacific. Not enough is known to 

 ascertain its host preferences but inshore carcharinid sharks seem to 

 be preferred hosts. 



This copepod is closely related to P. hicolor, but the natiu-e of the 

 caudal ramus separates it easily from all other members of the genus. 

 Kirtesinghe (1950) notes the relationship between this species and 

 P. hicolor; he also suggests an affinity with P. satyrus on the basis of 

 the caudal ramus. A comparative survey of the genus shows this 

 not to be so, especially on that basis since the caudal ramus of P. 

 satyrus does not extend beyond the tip of the abdominal plate.

Specimens studied. — Paratype female from Formosa loaned to 

 me by Ho. Also 2 more collections of females from Formosa from 

 Galeorhinus species and Carcharinus gangeticus. Three collections 

 from Nosy Be, Madagascar, from Carcharinus leucas, C. sorrah, and 

 C. limhatus. A single collection from Durban, South Africa, from C. 

 leucas.
