Fig. 6 in Megascolex (Perichaeta) diffringens Baird, 1869 and Pheretima pingi Stephenson, 1925 types compared to the Amynthas corticis (Kinberg, 1867) and A. carnosus (Goto & Hatai, 1899) species-groups (Oligochaeta: Megadrilacea: Megascolecidae)

Fig. 6. Amynthas corticis - specimen from Incheon (NIBRIV261267, DNA sample w59) with enlargements of main characteristics; [boxed are sketches of GMs of two other sympatric specimens - IV261270]. The unusual arrangement of GMs around male pores suggested a new taxon but DNA did not differ from other A. corticis specimens (Fig. 1; Appendix and cf. A. hongkongensis, A. hatomajimensis and A. cruxus).
