<paragraph pageId="3" pageNumber="4">Adult: General characteristics given of mature, egg-producing parasite (Figure 1). Body elongated and ellipsoid, total length 5.707 (3.052-7.378), greatest width 2.278 (1.276-2.751), width at vagina 2.270 (1.276-2.739), haptor length 1.310 (912-1.616), haptor width 1.931 (1.232-2.182); haptor length to body length ratio 0.23; six haptoral suckers, mean diameter 564 (148-781), haptors internally supported by an elaborate skeletal structure. Two pairs of hamuli: inner pair 69 (48-95) long with a hamulus hook length of 21 (17-26); outer pair 138 (104-173) long with a hamulus hook length of 22 (19-26). Mouth sub-terminal. False oral sucker 788 (398-1 036) wide; pharynx length 539 (345-917), width 658 (391-881). Intestine bifurcates with no diverticula and no anastomoses present; caeca extend to the end of the body proper and do not join posteriorly nor do they extend into the haptor. Testis compact, mid-ventral, medial, and posterior to ovary (Figure 1); 401 (108-687) long and 564 (148-781) wide. Genital atrium median, ventral, posterior to intestinal bifurcation: 586 (302-816) in length with 123 (108-132) spines, 101 (93-106) long. Ovary, dextral, anterior, 38% of body length; ovary length 251 (102-330), and width 86 (27-124). Short tubular uterus anterior to ovary, containing up to eight eggs; length 227 (182-274), and width 144 (118-194). No intra-uterine development, operculated egg. Vitellarium extends throughout most of the body proper posterior to the pharynx except the central area around the gonads (Figure 1). Oncomiracidia. Marginal hooklets were observed and measured on slides prepared from incubated oncomiracidia (Figure 2). Marginal hooklet I found to be 28 (25-30) and hooklets II - VIII 27 (25-29).</paragraph>
