Fig. 2. Surface ultrastructure of the scolex and tentacular armature of Pa. otobothrioides. (A) Dorso-ventral view of the scolex dissected from the blastocyst showing the distal bothrial surface without complete median separation. (B) Pedunculus scolecis showing 2 bothria with free lateral and posterior margins. (C) Apical view of the scolex bothrial surfaces. (D) Capilliform filitriches. (E) External tentacle surface, metabasal armature with solid uncinate hooks. (F) Distal bothrial surface showing (G) hamulate spinitriches and (H) lineate spinitriches. Scale bars: (A,C) 100 μm; (D–H) 50 μm.
