Planche 3 Issued from : M. Madhupratap & P. Harida in J. Plankton Res., 1992, 14 (4). [p.558, Fig.3]. Female : A, P1; B, P2; C, P3; D, P4. Scale bar in mm.
Planche 4 Issued from : M. Madhupratap & P. Harida in J. Plankton Res., 1992, 14 (4). [p.559, Fig.4 A]. Female; A, P5 (anterior view).
Nota: P5 asymmetrical. coxa (B1) with proximal spinule row, basis (B2) with large posterior surface seta, very fine proximomedial spinule patch and a distal spinule row continuing on to lateral surface. Left basis (B2) extending over proximal corner of exopodal segment 1 with large bulbous ptojection at distomedial corner; right basis (B2) also extending over exopodal segment 1 with irregular medial margin. Exopodal segment 1 wit naked seta, exopodal segment 2 with stout medial spiriform process, both margins hirsute and small naked seta. Exopodal segment 3 with proximomedial spiniform process slightly lo,nger than exopodal segment 2 spiniform ptocess and appears divided distal to origin of basal process.
Planche 5 Issued from : M. Madhupratap & P. Harida in J. Plankton Res., 1992, 14 (4). [p.559, Fig.4]. Male: B, P5 (posterior view); C, P5 (anterior view). Scale bar in mm.
Nota: P5 posterior view : Coxa (B1) distomedial corners acute. Right leg -, basis (B2) with 1 large surface seta at midlength, 2 distal setae, rows of proximomedial spinules and a row of dorsolateral spinules. Endopodite consists of 2 processes, both oroiginating from the same base at the disyomedial corner of basis and with a hyaline process having an apical cleft in the middle. Medial process of endopodal spinifotrm with seta at the tip, lateral process stout, apex bulbous with irregular margin and a corona of small spinules. Exopodal segment 1 roughly triangular with a circular cluster of spinules at midlength, sculptured with 3 distolateral small ridges, 2 surface setae and distolateral corner ending in a small spine like process; outer seta long, recurved, reaching 3/4 of exopodal segment 2 with proximopmedial margin heavily serrate. Exopodal segment 2 elongate with distomedial knob, surface seta at midlength and outer seta 3/4 the length of segment. Exopodal segment 3 proximomedially swollen with spinules and 2 setae and tip finely serrate. Left leg basis (B2) with large surface seta, seta on medial margin and a distolateral row of spinules. Large recurved endopod originating from distomedial corner of basis, extending past midlength of exopodal segment 2, base swollen, apex with distomedial spinules and ending in a circular row of long spines. Exopodal segment 1 simple with naked outer seta. Exopodal segment 2 large, flattened and hemispherical with long outer seta, 3 surface setae and 1 terminal seta, medial margin with 3 setae. Anterior view: coxa (B1) with spinule row. Basis (B2) with row of spinules at midlength continuing on to the lateral sides and distal spinule row. Right exopodal segment 2 with fine distal spinules; left coxa (B1) with proximomedial very fine spinules; left exopodal segment 2 with proximomedial hairy patch extending distally along ridge.
The specific name, pankajus, refers to the lotus-like arrangement of clustered spinules at tips of both endopods and on right exupodal segment 1 (pankaj = lotus, origin-Sanskrit, gender: male).
