Emended diagnosis: Body large, elongate, fusiform. Tegument smooth, with few posterior annulations. Ventral sucker elongate, posterior, close to posterior extremity. Pharynx barrel-shaped, ventrosubterminal, surrounds mouth, smaller than ventral sucker; pre-oral lip reduced. Oesophagus long, sigmoid, lining developed, invested with glands along entire length. Oesophageal bulb well-developed, spheroid, distinct, smaller than pharynx. Intestinal bifurcation immediately posterior to oesophageal bulb; caeca 2, blind, extend to midpoint of body length. Testes 2, entire, ovoid, diagonal, in posterior third of body. Cirrus-sac prominent, entirely posterior to caeca, globular; ejaculatory duct short, eversible. Seminal vesicle partially external to cirrus-sac.

Genital pore posterior to caeca, equatorial, median, strongly muscular, laterally elongate. Ovary entire, post-testicular, median. Seminal receptacle prominent, canalicular. Vitellarium follicular; follicles dense, extend from level of pharynx to immediately anterior to testes; dorsal, ventral and lateral fields confluent. Uterus entirely pre-ovarian, coiled between testes, enters genital atrium sinistral to cirrus-sac. Eggs large, tanned, apparently unembryonated

In particular, the morphology of the female reproductive system is able to be well observed; we were able to discern the forked junction of the seminal receptacle, insemination chamber and oötype.
