Female: a, forehead (left side); b, urosome (left); c, d, e, genital somite (left, right, ventral, respectively); f, outer lobe of Mx1; g, P1 (anterior); h, P2 (anterior).
Nota: Similar in habitus to P; abyssalis
and P. calva
but can be distinguished.
Rostrum beginning some distance from suprafrontal sensilla, pointing nearly parallel to anterodorsal margin of forehead.
Dorsal wall of genital somite smoothly and broadly ciurved. Genital flange relatively low, with small but distinct posterior lobe pointing posteroventrad. Posterior edge of genital field produced into low ridge some distance from genital flange. Posterior margin of genital prominence slightly bulging and nearly perpendicular to, and merging in a curve into, posterior ventral wall of somite, which is nearly twice length of posterior margin of prominence excluding posterior edge of genital field.A low tubercular outgrowth close to ventral wall anterior to genital ^prominence on left side of genital somite. Ventrally, genital somite widest anterior to middle, posterior lobe of genital flange pointing mediad (Fig.46-e).
Cephalosomal appendages similar to those of P. abyssalis
except that 1st endopodal segment of Mx1 with 7 setae (as in P. malayensis
); outer lobe with 6 long setae followed by a small proximal seta (as in P. abyssalis
Swimming legs similar to those of P. abyssalis
except that outer spine of 1st exopodal segment of P1 better developed and in P2 exopod, 4th outer spine only slightly longer than 2nd and incision setarating its marginal lobe short of reaching level of preceding incision.
