Fig. 5 Confocal maximum projections of Typosyllis antoni n. sp. Phalloidin–rhodamine labeling of adult specimens. Anterior is up in b and c, down in a and d, and right in e and f. a Lateral view of the anterior region, with everted pharynx (ph) and prominent dorsal cirri (dc), antennae (an), and palps (pl). The antennae exhibit prominent basal muscular sockets (dotted ring). b Ventral view of the anterior region showing the distinct longitudinal muscle bundles (lm) and the transverse muscle fibers (tm) forming semicircular fibers. c Dorsal view of the anterior region. Distinct longitudinal muscle fibers (lm) and the partly diagonal cross bracing transverse muscle fibers (tm) are exhibited. d Dorsal view of the posterior end showing the prominent pygidium (py) lacking distinct muscle bundles and the pygidial cirri (pc). e Lateral view of the midbody region, dorsal is up. The dorsal cirri (dc) insert at the base of the parapodium (pa). f Dorsolateral view of a midbody parapodial region. The dorsal cirri (dc) are represented by a prominent staining exhibiting a striped pattern; an antenna, ch chaetae, dc dorsal cirrus, lm longitudinal muscle fiber, mo mouth opening, pa parapodium, pc pygidial cirri, ph pharynx, pl palps, pp pharyngeal papillae, pr parapodial retractor muscle, py pygidium, tm transverse muscle fiber, vc ventral cirrus.
