Based on 12 gravid specimens. Body elongated, 1,53 (1,13–1,98) long, 398 (264–462) wide. Body tegument covered by very tiny spines, hardly visible with light microscopy but evident through SEM study. Oral sucker subterminal, 158 (128–181) long, 150 (123–171) wide, possessing four pairs of papillae around anterior borders of mouth opening. Mouth opening longer than wide, 56 (27–84 long, 35 (16–84) wide. Prepharynx elongated, relatively long 55 (18–99) long; pharynx 99 (51–153) long, 81 (34–129) wide. Esophagus 59 (39–80) long. Ventral sucker 168 (132–202) long, 166 (134–189) wide, 446 (352–542) from anterior end of body. Dispersed eyespots remnants in area between pharynx and oral sucker. Average ratio of oral sucker length to ventral sucker length 1:1.063. Average ratio of oral sucker width to ventral sucker width 1:1.10. Ceca bifurcating approximately half distance between pharynx and ventral sucker, 319 (203–481) from anterior end of body; ceca end blindly, left cecum 201 (161–256) from posterior body end, right cecum 193 (131–237) from posterior body end. Testes subspherical, located in tandem, contiguous; anterior testis 177 (130–254) long, 184 (134–234) wide; posterior testis 213 (157–264) long, 192 (144–250) wide. Postesticular space 337 (251–452), representing approximately 22% of body length. Cirrus sac absent. Seminal vesicle free in parenchyma, submedian, elongate, lying dorsal to ventral sucker, 139 (86–158) long, 94 (72–113) wide, inconspicuous hermaphroditic duct opening through medial genital pore, immediately anterior to ventral sucker, 423 (350–514) from anterior end of body. Ovary subspherical, 91 (76–105) long, 83 (64–99) wide, dextral, located approximately 2/3 distance between ventral sucker and anterior testis. Seminal receptacle spherical, dorsal to ovary, sometimes overlapping. Laurer’s canal muscular not observed. Vitelline follicles in two fields mainly extracecal, 664 (525–826) from anterior end of body, with some follicles confluent at anterior testis level, completely confluent in posttesticular space, with scattered follicles in area terminating 143 (54–98) from posterior end. Vitelline follicles extending from half distance between ovary and ventral sucker to posterior end of body. Uterus pretesticular, intercecal, occupying most of area between ovary and ventral sucker, confluent with ejaculatory duct to form inconspicuous hermaphroditic duct. Eggs 61 (51–70) long, 48 (42–57) wide. Excretory vesicle I-shaped, terminating in postesticular space; excretory pore dorsally subterminal.
