Female. — Body form as in figure 34. Length 8.2 mm and width 

 4.6 mm based on an average of 10 specimens. Dorsal thoracic plates 

 similar to those of P. satyrus and P. cranchii except that plates of 

 segment 2 extend only to about middle of plate of segment 4. Genital 

 segment 2.2 mm long and 3.0 mm wide. Abdomen 1-segmented as in 

 P. satyrus. Dorsal plate of abdomen nearly round (see fig. 35). 

 Caudal rami (figs. 35, 36) L78 mm long and with an inner lobe extend- 

 ing ventrally below abdomen. In some specimens lobes extending 

 toward midline almost touching and thus forming shelflike structure 

 bridging the rami. 



Oral area similar to that of P. satyrus. Second antenna (fig. 37) 

 and maxilliped (fig. 38) are illustrated to show minor differences in 

 shapes of segments and lengths of spines. Legs 1-4 modified as in P. 

 satyrus and with the following spine and setal formula : 



leg I leg Z leg S leg 4 



exp. end. exp. end. exp. end. exp. end. 



seg. 1 1:0 0:0 1:0 0:0 1:0 0:0 VI I or 



seg. 2 VI III X IV VI I or II 



Formula like that of P. satyrus and P. cranchii except in variation of 

 numbers of spines on last podemere of expodite of legs 3 and 4 (fig. 39).
