Diagnostic description of female, — Cephalothorax (fig. 14a) con- 

 sisting of cephalic, maxilliped-bearing and first pedigerous segments, 

 narrower anteriorly than posteriorly; lateral margins flatly convex, 

 posterior concave, with 8 irregular denticulations medially. Frontal 

 region narrow, with distinct median depression. Second through 

 fourth pedigerous segments (figs. 146, c) free, second and third each 

 with single plate covering median dorsal surface, second with pair of 

 ovoid plates originating from lateral dorsal sm-face, extending pos- 

 teriorly and laterally; third pedigerous segment with pah* of small, 

 posteriorly rounded plates dorsally, extending posteriorly and laterally, 

 slightly overlapped by plates of second pedigerous segment. Fourth 

 pedigerous segment with single, large, apron-shaped plate dorsally, 

 extending posteriorly over most of genital segment. 



Genital segment (figs. 146, c) wider than long, slightly narrower 

 posteriorly than anteriorly; lateral margins flatly convex, posterior 

 and anterior margins concave laterally, irregular medially, postero- 

 lateral projection each tipped by single denticulation. Large, rounded 

 anal lamina attached to dorsal surface of posterior concavity, ex- 

 tending posteriorly to distal end of caudal rami. Abdomen (fig, 14c) 

 1-segmented, extending posteriorly from posteroventral surface of 

 genital segment; narrower anteriorly, broadly rounded posteriorly, 

 bearing pair of heavily sclerotized, distally pointed caudal rami 

 directed posteriorly and laterally. Caudal rami attached to abdomen 

 by broad base formed of cuticular extension of proximal half of ramus. 



Color pattern of alcohol preserved material similar to that of 

 Pandarus satyrus. 



Antennule (figs. 14f/, 15a) 2-segmented, fu'st segment more than 

 twice the length of second, cui-ved posteriorly in distal region; with 

 approximately 23 naked setae on anterior ventral sm-face. Second 

 segment rounded distally, with approximately 7 fine setules on distal 

 surface and 1 on medial posterior surface. Antenna (figs. 14c^, 156) 

 3-segmented, proximal segment with oval adhesion pad, smaller than 

 postantennular adhesion pad, extending across ventral surface of most 

 of cephalic depression bearing antenna. Second antennal segment 

 longer than first, with heavily sclerotized, knob-shaped projection on
