Amynthas exilisarius exilisarius— Blakemore 2007a: 35; Blakemore 2008b.

Type locality. Vietnam (Hanoi: Soc Son ).

Type material. ZMUM (W.214), Russia.

Examined material. 1 C (SORC-V.045.01) forest at elevation of 900m a.s.l., Tam Quan, Tam Dao, Vinh Phuc, 19/4/1984.

Distribution. Only known from Vietnam.

Remarks. Thai (1983) proposed a new subgenus Terrata of the genus Pheretima , and placed the species under the new subgenus. Blakemore (2007a, 2008b) considered it as " species inquirenda ". Material was re-examined and absence of male copulatory pouches and hence placement of the species in Amynthas is confirmed here.
