Description
Trunk is sausage shaped and measures 43 mm in length and 20 mm across the broadest part. Proboscis is 19 mm in length, fleshy, gradually narrowing anteriorly and somewhat tubular in shape by ventral inflection of its lateral margins. Proximal 1/3rd of the lateral margins are broken in the form of a series of ridges. Across the broadest part the proboscis is nearly 10 mm wide from one edge to another. Body wall is thick and covered with sparsely distributed papillae. Longitudinal muscle bands are 10 in number with transverse fascicles between the bands. Ventrally about 5 mm posterior to the mouth 2 very small dark brown hooks with golden yellow tips are present. Genital pores are indistinguishable.

Gonoducts 2 pairs, pear shaped and located posterior to the ventral hooks; the posterior part is larger in size. Gonostome basal, gonostomal lip drawn into two spirally coiled filaments. Dorsal vessel is robust, neuro-intestinal vessel is single throughout, and the ring sinus is narrow. Anal vesicles are two brown tubes about 15 mm in length and 1.5 mm in breadth and studded with excretory funnels.
