Pontellopsis laminata  C.B. Wilson, 1950   (F,M)
Ref.:
C.B. Wilson, 1950 (p.308, Descr.F, figs.F); Silas & Pillai, 1973 (1976) (p.777); Pillai, 1977 (1982) (p.61, figs.F,M, Rem.F,M)
Espèce Pontellopsis laminata - Planche 1 de figures morphologiquesissued from : C.B. Wilson in Bull. U.S. natn Mus., 100, 14 (4), 1950. [Pl.31, Figs.470, 471].
Female (from Palawan Island: Philippines): 470, habitus (dorsal); 471, urosome (dorsal).

Nota: Genital segment increasing in width to its posterior margin, where it is as wide as long. 2nd abdominal segment with an acute spine on each lateral margin; the one on the left is long and narrow and points diagonally bacward, while the right one is shorter and wider and extends outward at right angles to the urosome axis; to the dorsal surface of the segment at the right posterior corner are attached two rounded laminae, the smaller anterior one is elliptical in outline and is usually turned down over the ventral surface, the larger posterior one extends backward and inward above the anal segment and caudal rami and reaches the tips of the caudal setae; there is another smaller lamina attached to the posterior margin of the segment and extending back over the the anal segment and beyond its posterior margin. Usually yhese three complete the laminate armature of the urosome, but in one female there was a fourth large lamina attached to the left side and sweeping around backward and overlapping the one from the right. These laminae are chitinous and perfectly transparent but of course brittle and likely to be broken off. They still remained intact in 75 percent of the specimens. The genital protuberance on the ventral surface of the genital segment is at the posterior margin, and in most of the females a single spermatophore was attached to it; the long narrow discharge tube swept around and up over the right side of the urosome, and the body of the spermatophore trailed backward on the top of everything else
