Himasthla elongata cercariae, schemes of the body-wall musculature (ventral side). a: scheme showing the arrangement of longitudinal and some additional groups of muscles; b: scheme showing the arrangement of diagonal and some additional muscle groups. al – anteriolateral muscle fibers; ar – anterioradial muscle fibers; csp – collar spines; dm – diagonal muscle fibers; ium – muscle fibers of iU-shaped set; lm – longitudinal muscle fibers; os – oral sucker; pcdm(I, II, III) – specific groups of the diagonal muscle fibers in the precollar region; pclm (I to IV) – specific groups of the longitudinal muscle fibers in the precollar region; pcom – oblique muscle fibers in the precollar region; pr – posterioradial muscle fibers; t – tail; tmb – dense muscle bundles close to the tail basis; vllm – ventrolateral longitudinal muscle bands; vmlm – ventromedial longitudinal muscle fibers; vs – ventral sucker. Scale bars 10 μm
