Fig. 8 Light microscopy pictures of regenerating specimens of Typosyllis antoni n. sp. All pictures are dorsal views except d2 (ventral view). a, c, e anterior end, b, d1, d2, f posterior end. The dotted white line indicates the site of dissection. a At 4 days after dissection, the re-developing prostomium (ps), as well as the first two segments (1, 2) are visible (in other specimens also three segments were observed). The prostomium shows palps (pl), antenna (la, ma) and two pairs of eyes (ey). Dorsal tentacular cirri (dt) of the first segment occur. b After 4 days, the pygidium (py) with the anal cirri (ac) and the median papillae (mp) are regenerated. c At 6 days, all in a described anterior structures have grown. Pharynx (ph) is re-developed, connecting the mouth opening (not visible) with the
