General configuration, sections, and details of the reproductive structures.
(a) Schematic structure of the male reproductive system, showing the connection between the testes and seminal vesicles (via vasa deferentia) as well as the connection of seminal vesicles and accessory glands to the sperm pump; (b) Dorso-ventral (coronal) section at the level of the accessory glands and seminal vesicles ducts. (c, d, e) Antero-posterior (axial) sections of planes shown with blue, green, and red lines numbered as 1, 2, & 3, respectively; (f) Sagittal section; (g-k) sperm pump and ejaculatory duct (g: right lateral view, h: sagittal section i: ventral view, j: antero-posterior view, k: postero-anterior view); (l-n) Detail of the anterior plate on the sperm pump showing the foramens (l: antero-posterior view, m: postero-anterior view, n: dorsal view).

Internal details of the terminalia and aedeagus.
(a) CTVox volume rendering, (b-f) Amira volume renderings, (g) light-microscope right lateral view of the aedeagus, mounted in a slide. Volume renderings with details of the male hind abdominal segments showing the anatomical position of the aedeagus structures and associated musculature. (a, d) right-lateral, (b) postero-anterior, (c) antero-posterior, transparented to display the sclerotized structures of the aedeagus.

(a, h) angled left-lateral posterior view, (d) angled right latero-anterior view, (b, e, k) dorsal, (c, g) right-lateral, (i) postero-anterior, (f, j) angled dorsal, (l) ventral. (d-l) For visualization, the renderings have been transparented with Amira software to eliminate soft tissues and enhance harder-sclerotized structures.
