(a) The second leg, consisting of 6 segments, namely, coxa (c), trochanter (t), femur (f), genu (g), tibia (b), and tarsus (s) terminating with pulvillus (v), beside the peritreme. The coxa carries a row of minute conical tubercles (arrow) near the peritremal plate (pp). (b) Peritremal plate (pp) surrounding peritremal canal (pc) which contains minute papillae. (c) Higher magnification of the row of minute conical tubercles (ct) on the coxa. (d) Pulvillus of the first leg carrying 2 curved claws (cl), ventral longitudinal ribs (lr), two lateral laciniae (lc), and overlapping terminal integumental folds (f). (e) Pulvillus of 2nd–4th legs showing longitudinal integumental ridges (lr) on dorsal and ventral sides. (f) As in (e) showing terminal medioventral claws (cl), lateral laciniae (lc), and transverse ridges (tr).
