Planche 2 Issued from : Y. Ranga Reddy & Y. Radhakrishna in Hydrobiologia, 1982, 87. [p.263, Plate III, Figs. 1-11].
Female (from 16)32'-16°47'N, 81°4'-81°22'E): 1, habitus (dorsal); 2, postrior part of prosome and urosome with spermatophore (lateral); 3, posterior segment of prosome and genital segment (lateral); 4, segment genital (ventral); 5, caudal ramus; 6 & 6a, A1 and its modified seta; 7, P1; 8, P2; 9, P4; 10, P5; 11, egg sac.

Nota: Rostrum strongly developed with 2 long acute spines overreaching the 2nd segment of A1.
- Prosme twice the length of urosome.
- Head and 1st pedigerous segment separate, 4th and 5th pedigeous segments fused.
- Posterolateral corners of the 5th pedigerous segment rounded with a sharp, posterolaterally-directed spine; a few short hairs occur on the margin internal to the spine.
- Urosome 4-segmented.
- Genital segment slightly asymmetrical, proximally swollen with a short, strong spine on the right side; the armature of this segment is more complex than described by Sewell.
- Urosomites together with the caudal rami are in the proportion of 35 : 17 : 19 : 16 : 25.
- Caudal rami symmetrical, somewhat divergent, 23.3 times as long as broad with long coarse hairs on their inner margins. The five caudal setae are jointed; the middle seta the longest; a small sensory bristle lies between the inner 2 setae.
- A1 21-segmented, reaching a little beyond the posterior margin of prosome.
- The structural details of A2 and oral parts quite similar to those of P. binghami. Sewell'sremark that A2 of P. hickmanidiffer from others in possessing a row of spine-like processes on the margin of the last segment of the endopodite appears to be not well-founded as this character is shared by other species.
- P1- P4 are identical with P. binghami but for the spine pattern of the basipodite segments. In P1, 1 or 2 strong spines , present on the outer margin of coxa, are absent in other species.
- P5 asymmetrical, the left leg, particularly its 2 exopoditesegments, being more slender than their counterparts of the right leg. Each leg consists of 4 segments, 2 each of basipodite and exopodite. Coxa naked. Basis bears 1 seta on the posterior face. Exopodite 1 slightly over twice as long as broad with a small spine at the distal outer corner. Exopodite 2 has 1 spine at about its distal corner, and the segment proper ends in an out-curved, claw-like process serrated on both margins. Between this and the outer spine is a large spine with a lobe-like serrated process at its base on the inner side.
- The ovigerous female bears a single large, compact efgg sac, furrowed in the middle owing to the compression of urosome, with 24-38 individual eggs.

Planche 3 Issued from : Y. Ranga Reddy & Y. Radhakrishna in Hydrobiologia, 1982, 87. [p.263, Plate III, Figs. 12-15].
Male: 12, posterior part of prosome and urosome (dorsal); 13, same (lateral); 14 & 14a, right A1 and its segments 9-14; 15, P5 (posterior view).

Nota: Prosome as in the female except that the right spine of the 5th pedigerous segment is comparatively larger than its left counterpart and both are backwardly directed.
- Urosome 5-segmented; the posterodorsal margin of segments 2-4 with short spines; the 4 midorsal spines of 4th segment distinctly larger.
- Genital segment bears at its distal right corner a few small spines arranged in a short transverse row. In the lateral view from the left side, the 2nd urosomite, in addition, shows a few minute spines arranged in 2 short transverse rows.
- Caudal rami and setae as in the female.
- All appendages except for the right A1 and P5 similar to those of the female.
- Right A1 21-segmented, with 3 segments distal to the geniculation; segments 13-17 swollen; segment 3 with a long jointed aesthetasc besides 2 setae; segments 10-13 with a spine each, the spine on segment 10 characteristically bifid and hoohed; segment 17 with an unarmed tooth plate, overlapping the proximal part of the succeeding segment. The tooth plate on segment 18 with long, straight spine-like teeth in the proximal 2/3. Segment 19 has 2 unarmed 'tooth plates'.
- P5 asymmetrical, biramoius; basipodite 2-segmented, exopodite 3-segmented in the right leg and 2-segmented in the left. Right leg with coxa naked; basis quite larger than coxa and bears on its outer aspect a Y-shaped spinous process (i.e. endopodite), the two arms of which are nearly of equal length; basis has near the distal outer margin a few spinules arranged in a short transverse row, and 1 short seta at about the centre of the segment on the posterior face. Exopodite 1 has on the outer distal angle a Y-shaped spinous process, the outer arm of which has a short subapical spine; the segment also has a row of short blunt spines on its proximal inner margin. Exopodite 2 longer than broad, having on its distal outer region a short thick spine with serrated margins; near this spine lie a few minute spines on the outer margin; at the middle of the inner margin of the same segment lie a short blunt spinous projection and 1 seta. Exopodite 3 bent inward, 'sickle-shaped', apically drawn out into a slender spinous process, and having on the proximal inner side a pair of short setae, one of which lies on a small lobe; the inner margin of the segment, distal to the lobe, serrated. Left leg with coxa and basis as in the right leg; the endopodite long, unjointed and 'fringed'. Exopodite 1 has a small spine at its distal corner. Exopodite 2 narrow at its base and expands distally into a large thin plate, whose ornamentation can be best understood from the figure.
- Colour: Light brown in preserved specimen. A few orange red spots at the base of Mxp and on the ventral part of the anal segment.
