Pontella pulvinata  C.B. Wilson, 1950   (F,M)
Ref.:
C.B. Wilson, 1950 (p.295, figs.F,M); Silas & Pillai, 1976 (p.776)
Espèce Pontella pulvinata - Planche 1 de figures morphologiquesissued from : C.B. Wilson in Bull. U.S. natn Mus., 100, 14 (4), 1950. [Pl.16, Figs.198, 202, 203].
Female (from Okhotsk Sea: off Robben Island): 198, habitus (dorsal); 202, Md; 203, P5.

Nota: Head bordered on each side by a large membrane carrying a lateral hook. 4th and 5th metasomal segments fused, posterior corners produced into thick fleshy triangular asymmetrical pads, the one on the right wider and longer than the one on the left, nearly reaching the posterior margin of the genital segment; the posterior ends of the pads broadly rounded with a minute spine at the very tip. Urosome 3-segmented and very asymmetrical; the dorsal surface of the genital segment is produced to the left and backward into a curved spine; on the right side of the segment and nearer the posterior margin is a short blunt process curved over ventrally (concealed in dorsal view by the right pad at the corner of the thorax); on the left side is a rounded process projecting to the left (covered in dorsal view by the left pad at the corner). Caudal rami longer than wide, the left one is a little larger than the right


Espèce Pontella pulvinata - Planche 2 de figures morphologiquesissued from : C.B. Wilson in Bull. U.S. natn Mus., 100, 14 (4), 1950. [Pl.35, Fig.532].
Female: 532, last segments of metasome and urosome (dorsal).

Female: 245, urosome (dorsal).


Espèce Pontella pulvinata - Planche 4 de figures morphologiquesissued from : C.B. Wilson in Bull. U.S. natn Mus., 100, 14 (4), 1950. [Pl.16, Figs.199-201, 204].
Male: 199, habitus (dorsal); 200, middle segments of right A1; 201, urosome (ventral); 204, P5.

Nota: Genital segment considerably enlarged and is produced outward on the right side at the posterior corner into a short process cleft at its tip. Urosome 4-segmented. A1 reach the genital segment; the right one geniculate. The 2nd segment of the left P5 carries at its distal end a small spine which might be regarded as the rudiment of an endopod.
