FIGURE 8 in Asian pheretimoid earthworms in North America north of Mexico: An illustrated key to the genera Amynthas, Metaphire, Pithemera, and Polypheretima (Clitellata: Megascolecidae)
FIGURE 8. Amynthas carnosus. (A) Right male pore region and the associated genital markings (arrows). (B) Pre-clitellar genital markings paired mid-ventral on VIII and IX and eight spermathecal pores right behind eight genital markings (arrows). (C) Right spermathecae in VII–IX. Only the spermathecal diverticulum in IX is visible. (D) Right spermatheca in IX. (E) Right prostate gland and its duct (arrow). (F) Right intestinal caecum.
