Summary
The ultrastructure of tegumental and subtegumental receptors in the larva of Austramphilina elongata is described. The receptors are terminal swellings of dendrites and contain numerous small vesicles and neurofilaments which are predominantly peripheral. Tegumental receptors, together with a sheath consisting of basal lamina and tegument, project into the epidermis, and cross-striated rootlets were sometimes found in them. Subtegumental receptors lie below the tegument and ciliary rootlets were never observed in them. Anterior dendrites contain single centrioles and clusters of centrioles. The possible function of receptors and centrioles is discussed.
