Based on one specimen: Body 1,950 by 676; forebody 500 long, representing 26% of body length. Mouth subterminal; oral sucker subspherical, 263 by 270; prepharynx absent; pharynx subspherical, 101 by 109; ratio of width of pharynx to width of oral sucker 1:2.5; esophagus (could not be measured); ceca surpassing ovary posteriorly, occupying 47 % of postovarian space. Ventral sucker subspherical, situated in anterior 1/3 of body, 179 by 161; ratio of ventral sucker width to oral sucker width 1:1.7. Testes oval to subspherical, oblique; left testis 130 by 150; right testis 140 by 120. Genital pore median, located at level of posterior 1/3 of pharynx. Cirrus sac clavate, 164 long, representing 8% of body length. Ovary oval, 160 by 150; postovarian space 1,196 long, representing 61% 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 36 (33–40) by 22 (20–23). Excretory system not visible.
