Cercariae and metacercariae of  Renylaima capensis.  A) photomicrographs showing living cercariae from sporocysts infecting Ariostralis nebulosa; note extension (left) and contraction (right) capacities in the same acaudate cercaria and small developing immature cercaria (centre) with caeca not yet reaching final part of body and terminal tail; B) acaudate mature cercaria from inside a sporocyst in ventral view; C) mature cercaria from a sporocyst showing absence of postacetabular rounded undifferentiated genital primordium typical of brachylaimids, but evident differentiation of genital structures; D) mature cercaria from a sporocyst showing ventral genital pore (gp); E) acaudate metacercaria from Ariopelta capensis in ventral view; F) long prepharynx (pp) in specimen of metacercaria in ventral view; G) tegumental spinulation in a metacercaria in ventral view; H) ventral genital pore (gp) in caudate metacercaria in ventral view.
