Amynthas asacceus— Tsai et al. 2001: 284; Blakemore 2007a: 9; Blakemore 2008b. Pheretima pusilla Ohfuchi, 1956: 138 (non Ude, 1893 = A. minimus ), synonymized by Tsai et al. (2000, 2001). Pheretima medipusilla Nakamura, 1999: 2 , nom. nov., pro Pheretima pusilla Ohfuchi, 1956 .

Type locality. China (Hainan).

Type material. Unknown.

Records from Vietnam. Yen Bai (Luc Yen; Bao Ha) ; Ninh Binh (Cuc Phuong NP) (Do 1994; Le 1995a; Thai 1982).

Distribution. China, Japan ( Chen 1938; Nakamura 1999).

Remarks. An "incorrect original spelling" (under ICZN, 1999: Art. 32.5.1.1) as Pheretima assaccea was subsequently corrected by Chen in an ERRATA sheet to asaccea ( Tsai et al. 2001). Thus, it is often misspelt as " Amynthas assacceus ". No re-examination was made because of lack of available specimens. Do (1994) stated that the population found in northwestern Vietnam has additional genital markings on spermathecal region.
