Amynthas carnosus carnosus ( Goto & Hatai, 1899 )

Blakemore, Robert J., 2013, 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), Journal of Species Research 2 (2), pp. 99-126 : 101

Amynthas carnosus carnosus ( Goto & Hatai, 1899)

( Figs. 2-3 )

Delailed by Kobayashi (1936), Ohfuchi (1937) and Blakemore (2012a; 2013a; 2013b) (cf A. pingi described below). DNA data ( Fig. 1 ) indicates a new sub-species as next described.

Figures

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. 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. 1. Phylotree from MEGA5 program Maximum Likelihood defaults - sample codes explained in the Appendix; ◆- samples have figured specimens; ◇- ex GenBank. Appears to show significant genetic difference between specimens superficially compliant with broad A. corticis definition as discussed below that taxon herein. Synonym priority for either Gp 1 or Gp 2 is currently unresolved.
