Pontellopsis herdmani Thompson & Scott, 1903 (F,M) | |
| | | | | | | Syn.: | no Pontellopsis herdmani : Sewell, 1912 (p.375, figs.F, Rem.) | | | | Ref.: | | | Thompson & Scott, 1903 (p.236, 253, Descr.F, figs.F); Sewell, 1914 a (p.238, Rem.); 1932 (p.385, figs.F); 1948 (p.324); Kasturirangan, 1963 (p.57, figs.F); Saraswathy, 1966 (1967) (p.84); Silas & Pillai, 1973 (1976) (p.843, Descr.M, figs.F,M, Rem.); Greenwood, 1979 (p.109, figs.F, Rem.); Kimmerer & al., 1985 (p.428); Bradford-Grieve, 1999 b (p.208, figs.F, fig. 194); Mulyadi, 2002 (p.128, figs.F, Rem.); Othman & Toda , 2006 (p.316, figs.F,M); Al-Yamani & al., 2011 (p.78, figs.F,M) |  issued from : J.G. Greenwood in Proc. R. Soc. Qd, 1979, 90. [p.108, Fig.9]. Female (from Moreton Bay, E Australia): a, habitus (dorsal); b, urosome (dorsal); c, urosome (dorsal); d, posterior part of thorax and urosome (lateral right side); d, P5.

 issued from : E.G. Silas & P.P. Pillai in J. mar. biol. Ass. India, 1973 (1976), 15 (2). [p.843, Fig.31]. Female (from Gulf of Manaar): a, urosome (dorsal); b, P5. Male (from South Kerala Coast): c, urosome (dorsal); d, right A1 (distal part); e, P5. Nota: Posterior corners of Th5 modified into a rounded lobe on its left side and into an acuminate long spine on its right side, which is directed ventrad and curved inwards; tip of this process reaches mid-margin of ouosomal segment 3. Urosomal segment 1 with 2 small spinuous setae at its right distal margin. Urosomal segment 2 not modified. Urosomal segment 3 with a prominent projection at its right margin beset with small denticles. caudal rami asymmetrical, left ramus broader than long, while right ramus is longer than broad. Right A1 geniculate, segment 14 with a moderately long spine with a flagellum at its tip; segment 17 with a dorsal plate, finely serrated; segment 18 with dorsal denticles more triangular and well packed; segment 19 of fusion segment 19-21 with 5-7 flagellum like setae arranged radially. P5 bears a close resemblance to that of P. krameri; right leg with a chela, thumb of chela is long, exceeds length of claw and is serrated at its apex; inner margin of hand with a triangular protuberance; claw more or less straight, with striated outer margin; it is proximally thicker and tapers to apex; inner margin of claw with 2 setae and with another seta at its apex. Left P5 with terminal segment carrying 2 subequal spines distally and 1 outer marginal spine; inner margin with a band of setae; subterminal segment with a disto-lateral spine. Scale as in Calanopia minor. Remarks: The present material differs from the original description of this species by Thompson & Scott (1953) in that, the genital segment has 1 dorsal and 1 right lateral spine instead of 2 thorn-like projection on the left side. Sewell (1912, p.375) described a form 'intermediate' between P. herdmani and P. macronyx and commented that these are different forms of a single variable species; later (1935, p.388-390) he dscribed this 'intermediate' form as P. scotti. The male of this species, which remained undescribed so far shows cose resemblance to that of P. krameri; the diagnostic characters of the P5 separates this species from the former.

 issued from : Mulyadi in Treubia, 2002, 32; [p.129, Fig.47]. Female (from S Java): a, habitus (dorsal); b, metasomal somite 5 and urosome (dorsal) from another specimen c, metasomal segment 5 and urosome (lateral); d, urosome (ventral); e, P5. Nota: The present female differs from the female figured by Thompson & Scott (1903), Silas & Pillai (1973), Greenwood (1979) in having: the urosomal somite 1 has 2 unequal processes on anterior part, 1 spine-like process on right posterior margin, and 1 rounded process on left posterior margin; the P5 almost symmetrical with 3 outer spines and bifurcated apex.
