Ventral sucker oval, situated in anterior 1/3 of body, 200 by 227; ratio of ventral sucker width to oral sucker width 1:1.1. Testes spherical to subspherical, slightly oblique; right testis 88 by 95; left testis 85 by 92. Genital pore submedian located immediately anterior to cecal bifurcation. Cirrus sac clavate, 125 long, representing 7% of body length. Ovary subspherical, 115 by 93; postovarian space 1,000 long, representing 58% of body length. Uterus extensive, filling hindbody. Vitelline follicles distributed along ceca in lateral fields from level of posterior 1/3 of oral sucker to near level of cecal ends posteriorly. Eggs 46 (43–48) by 29 (28–30). Excretory system not visible.

This specimen appears to have been cold fixed without coverslip pressure. It is contracted, irregular in shape and the body has been rolled to one side displacing the ventral sucker and genital pore to the right. Additionally, the pharynx is pulled anteriorly into the posterior aspect of the oral sucker.
