FIGURE 4. (D–F) Line
drawings of Hornellobothrium najaforme n. sp. (D) Whole worm. (E) Scolex. (F) Mature terminal proglottid; arrowheads indicate level at which sections
in Fig. 6E and F were taken. 
FIGURE 6. Light micrographs. (E) Cross section of mature proglottid of Hornellobothrium najaforme n. sp. at level between ovary and cirrus sac. (F) Cross section of mature
proglottid of H. najaforme n. sp. at level slightly posterior to ovarian bridge. (I) Fusiform eggs of Hornellobothrium najaforme n. sp. with bipolar irregular fibrous extensions.

FIGURE 5. (J–R) Scanning electron
micrographs of Hornellobothrium najaforme n. sp. (J) Scolex and laterally expanded immature proglottids (i.e., hood); small letters indicate location of
details shown in P–R. (K) Scolex; small letters indicate location of details shown in L–O. (L) Distal bothridial surface with gladiate spinitriches and
acicular to capilliform filitriches. (M) Proximal bothridial surface with denser gladiate spinitriches and capilliform filitriches. (N) Scolex proper anterior
to bothridia with capilliform filitriches. (O) Scolex proper posterior to bothridia with spathulate spinitriches and capilliform filitriches. (P) Laterally
expanded immature proglottids (i.e., hood) with acicular to capilliform filitriches, with small scolopate spinitriches along posterior proglottid margin.
(Q) Posterior proglottid margin with small scolopate spinitriches. (R) Proglottid surface with capilliform filitriches.
