FIGURES 11–16. Macrobothriotaenia ficta (Meggitt, 1931) from Xenopeltis unicolor. 11–13. Flattened scolex of mounted specimens (11, 12. adult specimen. 13. juvenile specimen, Vietnam, MHNG-PLAT 45476). 14, 15. Mature and pregravid proglottides, respectively, dorsal view, Thailand (BMNH 1976.4.13.14–15). 16. Gravid proglottis, ventral view, Vietnam (MHNG-PLAT 75454).

FIGURES 1–10 in Macrobothriotaenia ficta (Cestoda: Proteocephalidea), a parasite of sunbeam snake (Xenopeltis unicolor): example of convergent evolution

FIGURES 1–10. Macrobothriotaenia ficta (Meggitt, 1931) from Xenopeltis unicolor. Scanning electron micrographs. 1. Scolex, apical view. 2. Scolex, lateral view. 3. Detail of a sucker, apical view. 4. Lower part of the exterior surface of a sucker. 5. Capilliform filitriches at level of the apex surface. 6. Capilliform filitriches at the upper marginal surface of a sucker. 7. Luminal surface of suckers covered with capilliform filitriches and few gladiate spinitriches. 8. Non-adherent surface of suckers covered with long capilliform filitriches and few gladiate spinitriches. 9, 10. Posterior part of suckers and proliferation zone covered with long gladiate spinitriches. Note: small black numbers correspond to the figures showing higher magnification images of these surfaces.

Figure 1. Habitat used by A. castelnaudii in Abra Malaga, along the Cusco-Machu Picchu road with some patches of Polylepis forest (a), mixed with open areas and fragments of shrubs and mid-height trees belonging principally to the families Ericaceae and Asteraceae (b), at the southeastern Peruvian Andes.

Figure 3 in First description of the nest, eggs, and nestlings of White-tufted Sunbeam (Aglaeactis castelnaudii) and incubation behaviours of Shining Sunbeam (A. cupripennis) in the southeast of Peru

Figure 3. Nest, eggs, and incubation behavior of A. cupripennis for 10 days early in the incubation period (a) female incubating on the nest (Photo: D. Ocampo), showing the temperature sensor cord inserted through the nest indicated by the white arrow; (b) eggs (Photo: G. Londoño); (c) daily count of trips off the nest; and (d) duration of the trips. Notice that days 2 and 8 (brown background) had the highest values of number of trips and the shortest average trip duration which might be a different incubation strategy compared to the other days of monitoring.
