Species Pontella spinipes - Plate 2 of morphological figures

Plate 2 Issued from : R.B.S. Sewell in Rec. Indian Mus., 1912, 7. [Pl.XXIV, Figs.1-4]
Male (from Bay of Bengal): 1, habitus (lateral right side); 2, right A1; 3, left P5; 4, right P5.

Nota: Head with side hooks. Rostral lens large and well-developed. The length of the abdomen and caudal rami contained nearly 3.5 times in that of the cephalothorax. Lef A1 24-segmented (11 th and 12 th segments partially fused) resembles that of the female. The grasping A1 resembles that of P. securifer; there are slight differences in the 18 th segment, which is shorter and has fewer teeth; the teeth are long and sharp and set fairly widely apart, diminishing gradually in size towards the distal end; the number varies from 25 to 30.; the toothed-plate is shorter than the segment itself; the distal segment of the knee-segments bears two toothed-plates, the proximal being the smaller and having from 8 to 11 arrow-shaped teeth; these two segments appear to vary very considerably in their relative proportions; in some the proximal is longer, while in others it is very shorter than the distal segment (proportions between 20-24 for the first and 19-22 for the second. The left P5 has a short terminal segment, bearing a stout curved spine and 2 more delicate processes at its distal extremity and a short spine on its external border, and the inner surface is covered with hair; The claw of the right P5 has the proximal segment with 3 teeth on its margin; the distal segment bears on its margin 3 rounded teeth.

Remarks

epiplagic. Neritic.
Sewell (1912) remarked the differences between the male of P. spinipes and P. securifer, and the relation between the size and the length of toothed plates on the fused segments 19-21. He concluded that in in the smaller specimens of P. spinipes, the distal plate of fused segment 19-21 longer than the proximal one.
