Fig. 16 Scanning electron micrographs of P. fimbriatus. A, Nauplius VI antenna, ventral; arrow indicates minute second exopodal segment; B, 

 Adult female antennule, aesthetasc on segment 5; C, Male copepodid V antennule, dorsal; D, Male copepodid IV antennule, ventral; arrow indi- 

 cates the spine on segment 4; E, Adult female antennule, double fusion on terminal segment, lateral. Scale bars A = 20 urn, B = 5um, C = 40 urn, D

aesthetasc, 2, 3, 7 + 1 aesthetasc. Second endopodal segment of 

 antenna (Fig. 8E) with 8 setae; distal seta VIII stronger than 

 others. Praecoxal arthrite of maxillule with 5 setae. Proximal 

 spinulose seta ornamented with long spinules. Praecoxa of 

 maxilla with short spinular row on outer margin. Basis of 

 maxilliped with 2 spinular rows laterally. 



Leg 1 (Fig. 10E) with 3-segmented exopod and endopod, 

 bearing spinular row posteriorly on second segment of exopod. 

 Intercoxal sclerite with anterior spinular rows distally. Leg 2 

 (Fig. 1 IE) with praecoxa bearing spinular row on outer margin. 

 Exopod and endopod 3-segmented: first segment of exopod 

 with proximal spinular row anteriorly, second exopodal and
