Tung T. Nguyen, Dang H. Lam, and Anh
D. Nguyen (2016) The giant earthworms from
Vietnam are being reviewed to consist of six species, Amynthas
dangi (Thai, 1984), A. munglonganus (Thai & Tran,
1986) comb. nov., A. ghilarovi (Thai, 1982), and
three new, A. munglongoides sp. nov., A. antoanensis
sp. nov. and A. konkakinh
sp. nov. All six species have lengths ranging 300-680 mm, diameter ca.
16-20 mm, and without copulatory pouches. The new species, A.
sp. nov. is characterised by three pairs of spermathecal pores in
intersegment 5/6/7/8, genital markings paired in vii, viii and xviii. A.
antoanensis sp. nov. is distinguished by four pairs of
spermathecal pores in 5/6/7/8/9, genital marking paired in viii, ix,
and xviii. A. konkakinh
sp. nov. is recognised by four pairs of spermathecal pores in
5/6/7/8/9, genital marking single in viii, paired in xviii. In
addition, a key to all six gigantic species in Vietnam is also provided.
