Redudasys brasiliensis sp. nov. Reconstruction of the musculature from confocal laser scanning microscopy images. (a) Schematic drawing of musculature in dorsal view. (b) Schematic detail of ventral musculature in the pharyngeal and the caudal regions. (c) Volocity-rendered 3D view of muscles in lateral view. Confocal micrographs of phalloidin-stained specimens. (d) Helicoidal muscles in the pharynx (arrow). (e) Detail of the pharynx posterior end with pharyngeal pores. asm = anterior semicircular muscle, cm = circular muscles, dlm = dorsal longitudinal muscles, llm = dorsal longitudinal muscles, mr = mouth ring, plm = pharyngeal longitudinal muscles, pp = pharyngeal pore, psm = posterior semicircular muscle, vlm = ventrolateral muscles.
