Based on two specimens (one intact and one somewhat distorted): Body 1,846 by 520; forebody 340 long, representing 18% of body length. Mouth subterminal; oral sucker circular, 160 by 160; prepharynx short; pharynx 52 by 62; ratio of pharynx width to oral sucker width 1:2.4; esophagus 21 long; ceca terminating posterior to posterior margin of ovary, occupying at least 20% of postovarian space (cecal ends not visible). Ventral sucker longer than wide, situated in anterior 1/3 of body, 135 by 133; ratio of ventral sucker width to oral sucker width 1:1.2. Testes opposite; left testis 159 by 135; right testis 143 by 122. Genital pore median, located immediately posterior to posterior margin of pharynx. Cirrus sac clavate, 143 long, representing 8% of body length. Ovary oval, 117 by 143; postovarian space 1,170 long, representing 63% of body length. Uterus extensive, filling hindbody. Vitelline follicles distributed in lateral fields from level of posterior margin of oral sucker to level of cecal ends posteriorly. Eggs 31 (27–35) by 22 (21–23). Excretory system not visible.

Both specimens appeared to be contracted and their bodies rolled to one side. The oral sucker has been pulled away from the anterior end of the body, the pharynx has been tilted to the right and the esophagus has become constricted. Additionally, the gonads have become shifted right and pulled into a tight, overlapping cluster at the level of the ventral sucker. The poor quality of these specimens precluded observation of some structures (e.g. ceca termination and bladder).
