Based on three specimens (two intact and one broken): Body 1,924 (1,352–2,496) by 537 (416–702); forebody 645 (560–730), representing 34% of body length. Mouth nearly terminal; oral sucker oval, 139 (47–230) by 220 (210–230); prepharynx short; pharynx oval, 77 (73–80) by 148 (86–210); ratio of width of pharynx to width of oral sucker 1:2.3 (1:2.1–1:2.4); esophagus 107 (0–213) long; ceca terminating well past posterior margin of ovary, occupying 38% of postovarian space. Ventral sucker oval, situated near posterior margin of anterior 1/3 distance of body, 179 (130–227) by 155 (133–177); ratio of ventral sucker width to oral sucker width 1:1.5 (1.3–1.6). Testes opposite or slightly oblique; right testis 138 (107–169) by 132 (125–139); left testis 136 (107–164) by 165 (156–174). Genital pore median, located immediately anterior to midlevel of esophagus. Cirrus sac 140 long, representing 7% of body length (n=1). Cirrus sac 140 long, representing 7% of body length. Ovary oval, 124 (104–143) by 122 (104–140); postovarian space 1,031 (580–1,482) long, representing 54% of body length. Uterus extensive, filling hindbody. Vitelline follicles distributed in lateral fields from midlevel of oral sucker to level of cecal ends, or slightly more posterior. Eggs 34 (29–39) by 21(16–26). Excretory system not visible.

One specimen (far left on slide) is clearly more fully developed (likely older) than the others, as indicated by having a larger body size, a longer, more developed postovarian space and noticeably more fully developed eggs in the uterus compared with the two other specimens. A limited number of structures could be observed in one specimen because the body was twisted causing the tegument to rupture, allowing the ovary and other organelles to protrude out of the body.
