Rostellar hooklets, continuous row between apical groups of large hooks (A); variation in hooklet form (B). 4. First (anterior) and last (posterior) hooks from row on cephalic peduncle. Interlandmark distances for length (A) and width (B) and posterior extension (C) measurements indicated by brackets on first hook. 5. Proglottid anatomy. (A) Mature proglottid in ventral view; (B) gravid proglottid in lateral view showing ovary in section.

All figures oriented with anterior end toward top of page. 6. Scolex, note large apical hooks of rostellum and microtriches on distal (adherent) surface of bothridium. 7. Hooklets forming contiguous row between large apical groups of hooks. 8. Cephalic peduncle. Note that only tips of spines protrude from longitudinal furrows. 9. Detail of rows of palmate microtriches on median distal bothridial surface. 10. Detail of palmate microthrix bearing 15 spinous processes; note small filamentous microtriches covering bothridial surface. 11. Detail of filamentous microtriches and circular pit on proximal bothridial surface. 12. Transition from proximal (right) to distal (left) surfaces of bothridium along posterior bothridial margin; note absence of palmate microtriches on proximal surface (right). 13. Detail of distal bothridial surface on lateral margin showing palmate microtriches; porelike openings are visible where microtriches were attached. Scale bars Figures 5 and 8, 100 µm; scale bars in Figures 7, 9, 12, and 13, 10 µm; scale bar in Figures 10, 11, 1 µm. |
