Pontella sp.A Silas & Pillai, 1976 (F) | |
| | | | | | | Ref.: | | | Silas & Pillai, 1973 (1976) (p.829, Descr.F, figs.F, Rem.) |  issued from : E.G. Silas & P.P. Pillai in J. mar. biol. Ass. India, 1973 (1976), 15 (2). [p.830, Fig.24]. Female (from West coast of India): a, habitus (dorsal); b, urosome (dorsal); c, idem (lateral left side); d, forehead (lateral); e, rostrum (anterior view); f, P5. Nota : Rostrum lacking in distinct lenses ; dorsal eye lenses rounded and placed wide apart ; ventral eye lens well developed. Head and Th1, separate, Th4 and Th5 separate ; posterior corners of Th5 modified into asymmetrical acuminate lobes, left side reaching middle of urosome while right lobe produced outwards, reaching proximal two-third length of urosome ; on dorsal view left lobe is longer than broad and with globular base, while right lobe is broader than long and with truncate base. Urosme 2-segmented, the suture separating urosomal segment 1 and urosomal segment 2 incomplete and hardly perceptible ; posterior margin of genital segment asymmetrically produced posterd, enveloping part of segment projects over caudal rami and almost fully right ramus ; in lateral view, postrior margin of genital segment projects over caudal rami as a ‘shield’ ; genital segment with its right lateral margin undulated an dits dorsal margin flattened with smooth indentations. Caudal rami small, with relatively short caudal setae. A1 24-segmented, reaching to posterior margin of last urosomal segment. P5 with exopod nearly 2.5 times longer than endopod.

| | | | | | | Loc: | | | off W & S India, off N Laccadive Is. | | | | N: | 1 | | | | Lg.: | | | (256) F: 4,42-3,77; {F: 3,77-4,42} | | | | Rem.: | epipelagic.
According to Silas & Pillai (1973, p.831) this species differs markedly from all known species under the genus by the characteristic of the urosome, caudal rami and the proportional lengths of exopod/endopod of P5. | | | Dernière mise à jour : 29/01/2015 | |
