Figs 1-10: light microscopy of Lanfrediella amphicirrus gen. nov. sp. nov. 1: dorsoventral view of the scolex (Bar = 100 μm); 2: immature segments in a dorsoventral view (Bar = 50 μm); 3: mature segments (Bar = 50 μm); 4: cross section of mature segment showing two groups of reproductive organs and two cirrus pouches (Bar = 50 μm); 5: reconstruction of a cirrus pouch with cirri showing the genital atrium, deferent channel and vaginal channel (Bar = 50 μm); 6: pregravid strobila segments showing the initial region of segmentation (Bar = 100 μm); 7: gravid segments showing the maturation of the paruterine capsules and visible segmentation (Bar = 100 μm); 8: posterior extremity showing gravid segments (Bar = 100 μm); 9: detail of a gravid segment where it is possible to observe two paruterine capsules per segment (Bar = 50 μm); 10: details of eggs showing the outer envelope, embriophore, and the oncosphere (Bar = 30 μm). 
Figs 11-15: longitudinal and cross-sections of mature segments embedded in Historesin and three-dimensional (3D) reconstruction based on serial longitudinal sections of a strobila segment. 11: cross-section of mature segments showing testis (T), ejaculatory ducts (ed), vitelline glands (vg), viteline duct (vd), excretory channels (ec) and two cirrus (c) pouches (arrows) (Bar = 100 μm); 12: longitudinal section of a strobila with mature segments showing the presence of two c pouches (arrows) in each lateral side of the strobila (Bar = 100 μm); 13: detail of a c pouch in a longitudinal section of mature segments in which it is possible to observe the insertion of ed, c, female duct (fd) and the copulatory channel (cc) (Bar = 100 μm); 14: superior view of in the transversal axis of 3D reconstruction where is possible to observe the internal position of two lateral rows of c pouches (arrows); 15: dorsoventral view in 3D reconstruction showing the position of c pouches (arrows) in each lateral margin of the strobila. 
Figs 16-22: scanning electron microscopy of Lanfrediella amphicirrus gen. nov. sp. nov. 16: general view of relaxed scolex showing the suckers (S), absence of a rosteolum or apical organ (Bar = 100 μm); 17: overall view of contracted scolex showing morphology of S in this moment (Bar = 100 μm); 18: internal details of S (asterisk) in contracted scolex. Note the absence of spines or any other structures (Bar = 10 μm); 19: internal details of S (asterisk) in contracted scolex (Bar = 100 μm); 20: details of the microtriches close to border of S (Bar = 10 μm); 21: details of microtriches in immature segments (Bar = 10 μm); 22: details of microtriches in mature segments (Bar = 10 μm). 
Figs 23-28: scanning electron microscopy of mature segments and differential interference contrast (DIC) of mature segments of Lanfrediella amphicirrus gen. nov. sp. nov. 23: lateral view of a mature segment showing the segmentation (arrow) and genital pores (gp) (Bar = 26 μm); 24: view of the opposite side of the segment in Fig. 23 showing the gp and a partly extroverted (C) (Bar = 20 μm); 25: view of the region of the gp region observed in Fig. 23 (Bar = 10 μm); 26: details of the cirrus (c) located in the mature segment observed in Fig. 24 (Bar = 5 μm); 27: image of DIC of mature segments with the best-adjusted focus obtained using the CombineZP software showing c extroverted with many spines (arrows)
(Bar = 100 μm); 28: partially extroverted c (Bar = 3 μm)
Figs 29-33: scanning electron microscopy of mature and gravid segments of Lanfrediella amphicirrus gen. nov. sp. nov. 29: mature segments of parasite showing the segmentation (arrows) (Bar = 100 μm); 30: gravid segment view in strobila where is possible to observe the segmentation (arrows) (Bar = 100 μm); 31: posterior end of a strobila showing the segmentation of gravid segments (arrows) (Bar = 400 μm); 32: end portion of the parasite showing the constrictions between gravid segments (arrows) (Bar = 100 μm); 33: isolated gravid segment. Note the elliptical morphology, characteristic of this stage, and the absence of genital pores (Bar = 50 μm). Best viewed in Firefox
