Fig. 8 Schematic drawing of the nervous system in Rastrognathia macrostoma as inferred from serotonin-like (a–c) and tyrosinated tubulin-like (d and e) immunoreactivity and CLSM. a Entire body. b Head and pharyngeal regions, dorsal structures. c Head and pharyngeal regions, ventral structures. d Head and pharyngeal region, projection of both dorsal and ventral structures, dorsal view. Only one out of four pairs of compound cirri is shown. e Posterior region, dorsal view.
