Abstract
This paper describes four new species earthworms from Hunan and Anhui provinces, China, Amynthasxiangtanensis Qiu & Jin, sp. nov., Amynthastaoyuanensis Qiu & Jin, sp. nov., Amynthasxuanchengensis Jin & Li, sp. nov. and Metaphiredonganensis Jin & Jiang, sp. nov.Amynthasxiangtanensissp. nov., and A.taoyuanensissp. nov. belong to the Amynthascorticis group. Both have four pairs of intersegmental spermathecal pores in 5/6-8/9; male pores in segment XVIII, separated by 1/3 of body circumference, each on top of a slightly raised porophore, surrounded by several tiny genital papillae. Amynthastaoyuanensissp. nov. prostate glands are degenerated. Amynthasxuanchengensissp. nov. belongs to the Amynthasmorrisi group, it has two pairs of spermathecal pores in 5/6 and 6/7; male pores in XVIII, separated by 1/3 of body circumference, each on top of a slightly raised, circular porophore. Metaphiredonganensissp. nov. belongs to the Metaphirehoulleti group. It has three pairs of spermathecal pores in 6/7-8/9; male pores in XVIII, separated by 1/3 of body circumference, each on the bottom center of the longitudinal copulatory chamber.
