Nanaloricus sp. Light micrography of adult stages (A and C) and body musculature visualized by fluorescently-labeled phalloidin staining and CLSM (B and D). Anterior faces upwards in all aspects. A: Same specimens as in B. Note that the introvert is fully retracted as in the specimen shown in C. B: Ventral view. Note that the net-like structure is located posteriorly to the neck circular muscle. C: Same specimens as in D. D: Dorsal view. The circle encloses a few thin longitudinal muscles folding inwards. Abbreviations: *, pharyngeal bulb musculature; an, anus; atI-V, abdominal transverse muscles; btr, buccal tube retractors; dl, dorsal longitudinal retractor muscle; lo, lorica; mcr, mouth cone retractors; nc, neck circular muscle; nl, net-like thin muscles; pa, pre-pharyngeal apparatus; ss, spinoscalid; sp, short posterior longitudinal muscles; te, testis; tl, thin longitudinal muscles; vl, ventral longitudinal retractor muscle; arrow, posterior short curved muscle.
