Pheretima angusticauda Thai, 1982: 821, fig. 1B; Do 1994: 55; Nakamura 1999: 20; Thai 2000a: 307. Pheretima (Amynthas) angusticauda— Thai 1983: 125.

Amynthas angusticaudus— Blakemore 2007a: 7; Blakemore 2008b.

Type locality. Vietnam (Ninh Binh: Cuc Phuong).

Type material. ZMUM (W.249), Russia.

Examined material. 10 C (SORC-V.009.01) limestone forests, Moc Chau, Son La, 12/04/1990; 12 C, 3 A (SORC-V.009.02) Thuy Phuoc, Hue, 07/01/1980.

Records from Vietnam. Son La (Moc Chau); Lao Cai (Sa Pa); Ninh Binh (Cuc Phuong); Thua Thien Hue (Hue city) (Thai 1982; Do 1994).

Distribution. Only known from Vietnam.

Vietnamese name. Giun đuôi nhọn.

Remarks. The species is variable in the number of spermathecae. It has been found in decaying woods (Do 1994). Material was re-examined and absence of male copulatory pouches and hence placement of the species in Amynthas is confirmed here.
