It is easy to imagine that such species as P. mangarevae Chevreiix 

 (1908), P. senegalensis Chevreux (1926), and P. zeylanicus (Walker 

 1904) are simply variants and the relationship of this complex is very 

 close to P. chelonophilus (Chevreux and de Guerne). 



A study of variation and growth stages based on topotype materials 

 is needed in this group before the taxonomy can be clarified.

Figure 35 



Diagnosis of male: Eyes large; palm of gnathopod 1 bulbous, 

 slightly longer than hindmargin of article 6, bearing stout setae; 

 anterodistal end of article 2 on gnathopod 2 with a large lobe, article 4 

 acutely produced, article 6 slightly elongated, anterior edge convex, 

 posterior edge nearly straight, palm not distinct from hindmargin, 

 bearing 2 small bumps and a crenulate margin between distal bump 

 and hinge, article 6 reaching two thirds along hindmargin; article 2 

 of pereopods 1-2 not inflated; spines sparse on uropods 1-2; hinddorsal 

 margins of pleonal segments 1 and 2 and pereonal segment 7 distinctly 

 elevated but carinae not developed.

 a, lateral view; b,c, gnathopods 1,2 ; d-f, pereopods 3-5; male, 2.3 mm., Abbott st.i. 41-

 produced but not as strongly as in such species as P. mangarevae 

 Chevreux (1908).
