Fig. 10. A 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. 10. A. corticis - Ohfuchi's (1937: fig. 4) three representative forms of his 'P. heteropoda' from Japan that is now a synonym of A. corticis. However, the central figure agrees almost exactly with A. diffringens types (as described herein) having markings just above spermathecal pores (Fig. 9) while the outer two specimens seem to agree with those A. corticis Korean specimens figured that provided DNA sample WO4- WO5 (Figs. 1, 5).
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).
Fig. 5 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. 5. Amynthas corticis - specimen from Korea (DNA sample WO4) showing X2 enlargement of aberrant spermatheca and the male pore 18rhs; second specimen (DNA sample WO5) and [boxed] the male pore 18rhs of third specimen (DNA WO6). Note: these specimens with superficially different GMs comply genetically (see Fig. 1 and cf Fig. 10).
Fig. 12 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. 12. Amynthas fornicatus showing Gates' (1935: figs. 5-6) most uninformative and irrelevant details of spermathecae invoking adage "missing the forest for the trees".
Fig. 3. A 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. 3. A. carnosus - sketch of Hikone specimen (Tokyo An-460 - DNA JET-112) showing ventral view of anterior and dorsal views of prostomium, clitellum and flared male pores posteriorly (other specimen An-461 and JET samples 113-115 agreed 100%). This specimen resembles P. pingi (cf Fig. 11) but its DNA agrees with A. carnosus (as in Fig. 1).
Fig. 2. A. carnosus - A 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. 2. A. carnosus - A. Korean specimen from Geoman (NIBR IV261234 - DNA w37). B. Japanese neotype of A. carnosus (Tokyo An- 435 from Blakemore, 2012a). These two specimens are almost identical morphologically allowing genetic comparison (Fig. 1).
Fig. 11 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)

Compare to Fig. 3.
