Pheretima abrevicapitata Thai & Le, 1993: 34, fig. 1B; Thai 2000a: 307. Amynthas? abrevicapitatus— Blakemore 2007a: 3; Blakemore 2008b.
Type locality. Vietnam (Hai Phong: Cat Ba Isl.).
Type material. SORC, Vietnam.
Records from Vietnam. Hai Phong (Cat Ba Isl.) (Thai & Le 1993).
Distribution. Only known from Vietnam.
Remarks. The species is fairly similar to Amynthas brevicapitatus (Thai, 1984) in having two pairs of spermathecal pores in intersegments 7/8/9, more or less same number of pre- and post-clitellar setae, prostatic duct S-shaped. However, it can be recognised by smaller body, prolobous prostomium, the absence of genital markings in spermathecal and male regions, spermathecal ampulla ellipsoid-shaped, and diverticula very short. The species was found inside decaying woods (Thai & Le 1993).
