.] With characteristics of genus. Body oval-elongate, rounded to somewhat truncate extremities, flattened dorsoventrally, widest in posterior 1/3 of body. Forebody contracted, 1/4 body length. Hindbody wider primarily than forebody, gradually widens in posterior 1/3 of body. Tegument smooth. Pre-oral lobe not observed. Oral sucker subspherical, subterminal, unspecialized. Ventral sucker prominent, unspecialized, muscular with thickwalled perimeter, transversely oval and wider than long, at junction of first and second 1/4 of body. Prepharynx absent. Pharynx muscular, oval, off center (rolled?) and overlapped by oral sucker. Esophagus contracted, short and straight. Intestinal bifurcation midway between oral and ventral suckers. Ceca long, moderately wide with consistent width throughout, terminate blindly near posterior extremity; left cecum slightly arcuate at posterior end.

Post-testicular region confined to posterior 1/6 of body. Cirrus pouch a slender, long, narrow tube with distinct wall, extends posteriorly to posterodextral margin of ventral sucker, passes anteriorly in a straight line dorsally over right side of ventral sucker to anterodextral margin of sucker, turns anterosinistrally to ventrally pass over left cecum to terminate near level of posterior pharynx and anterior esophagus. Seminal vesicle internal, bi-partite; proximal portion saccate, occupies only posterior 1/4 of cirrus pouch; distal portion tubular and occupies remaining anterior 3/4 of pouch. Pars prostatica and prostatic gland cells not observed but expected to be present with former located near distal end of cirrus pouch. Genital pore submedian (sinistral), pre-acetabular, at level of esophagus, midway between left margin and midline of worm. Genital atrium present.</paragraph>

Portions of proximal female system not observed; canalicular seminal receptacle and Laurer’s canal with dorsal opening expected. Vitelline reservoir large, submedian (dextral), sub-triangular in shape, immediately anterodextral to ovary. Path of oviduct not observed, but expected to arise anteriorly from ovary, receive both Laurer’s canal and main vitelline duct, then enter oötype which is itself expected to be anterior to ovary and surrounded by Mehlis’ gland cells. Uterus conspicuous, intercecal, wider proximally, extends posterior to ovary; proximal portion proceeds anteriorly from level of anterior testis, passes dorsally and narrows over center of ventral sucker; distal portion runs parallel and to left side of distal portion of cirrus pouch to enter genital atrium. Metraterm not observed. Vitelline follicles moderate in size, dense, round to globular to oblong in shape, ventral and lateral to ceca but not dorsal, extend longitudinally in 2 uninterrupted lateral bands from near posterior extremity anteriorly up to level of posterior margin of ventral sucker (right band to posterior margin of sucker; left band short of sucker by 52 μm), overlap lateral margins of posterior testis, not confluent in pre-ovar- ian region, in space between ovary and anterior testis, in inter-testicular region and in post-testicular region. Eggs collapsed and/or crenulated, small, operculate, amber, non-embryonated, non-filamented, numerous with nib on one pole; bloated / inflated eggs also observed.</paragraph>
