Description
Specimens are yellowish brown in color in the preserved state and proboscis missing. They measure 50-56 mm in length and around 7 mm across the broadest part. Body wall is thick and the papillae on the body wall are irregular in outline except at the posterior end where transverse rows of oval papillae alternate with the rows of smaller ones. Two dark brown ventral hooks are located a little posterior to the mouth. At the posterior tip there are two rows of slightly bent setae, in some specimens 7 in the anterior row and 4 in the posterior, in the other specimen setae present are 4 in the anterior row and 1 in the posterior. These setae have been found to come out easily from the preserved specimen.

Gonoducts 2 pairs, small oval in shape. Gonostome basal, simple annular gonostomal lip is borne on a stalk.
