Remarks

The morphological parameters of the present species are almost similar to the morphology of the already described species P. nandai by Sarkar (1953), and differ slightly in having longer testes and longer cement reservoir. The average size of anterior testis of male in the present specimens is 1115.3 × 254.0 µm which is different than the original description 505 × 150 µm by Sarkar 1953 and 622 × 188 µm by Amin et al. (2021a). Similarly, the average size posterior testis in the present specimens is 898.4 × 272.7 µm which is longer than the original description 450 × 150 µm by Sarkar 1953 and 606 × 184 µm by Amin et al. (2021a). Cement reservoir in present specimens ranged 684.8 × 187.1 µm, whereas it is relatively shorter in the earlier descriptions.
