The length of specimens in the present study is comparatively longer and the average size of proboscis hooks in 4 circles is longer in male. The average size of proboscis receptacle is slightly larger in the specimens of present study in male, whereas its size overlaps in case of the female. The average size of anterior and posterior testes in the original description is smaller in comparison to the specimens isolated in this study. Similarly, the average size of cement reservoir and saefftigen’s pouch is observed to be longer in the present specimens. Average size of cement gland in the present specimens measures 1422.6 × 136.8 with 24 – 27 cement gland nuclei (not mentioned in the original description).
