Cross section through ovarian isthmus in mature segment at position indicated by arrow numbered 5 in Figure 3. D, distal bothridial surface; O, ovary; P, proximal borthridial surface; T, testis; V, vitellaria.
FIGURE6S- 13. Scanning electron micrographs of Flexibothrium ruhnkei n. g., n. sp. 6. Scolex. 7. Enlarged view of bothridium. Location at which Figures 8, 10, 11 were taken are indicated with corresponding numbers. 8. Microtriches on proximal surface of flexed up portion of
bothridium. 9. Apical view of scolex with villus (V) retained in interbothridial space. Note open-faced grooves of bothridium (G), and flipped up portion of bothridium (F). 10. Microtriches on distal bothridial surface near margin of apical sucker. 11. Microtriches on face of distal bothridial surface. 12. Scolex attached to mucosal tissue. Note flipped up portions of 2 bothridia (F) making intimate contact with villi (V). 13. Scolex attached to mucosal tissue with villi removed from 2 open-faced grooves of 1 bothridium.
