Fig. 29From: The male sexual apparatus in the order Scorpiones (Arachnida): a comparative study of functional morphology as a tool to define hypotheses of homologyMale reproductive apparatus of Opisthacanthus (Nepabellus) cf. validus Thorell, 1876 (South Africa, Durban, MHNG). Hemispermatophore (a – c). Pre- (d, e) and post-insemination (f – g) spermatophores. Lateral (a, h, i), anterior (b, g), contra-lateral (c), and dorsal (f) aspects. The white arrow shows the deep invagination of the basal edge of the capsule. The black arrow indicates the site and direction of semen expulsion.
