In this study, we described two new species of the genus Amynthas with one pair of spermathecal pores in segment 8/9 from the riparian forest in Mt. Dinghu andtwo new Metaphire species with two pairs of spermathecal pores in segment 6/7–7/8 from a coniferous forest and an evergreen broadleaf forest in the Dadingshan station ofthe Nanling National Natural Reserve, Guangdong, China. The former two Amynthas species appear to be closely related to A. antefixus (Gates, 1935), Sichuan, China. However, A. dinghumontis is much smaller, and its slightly convex ellipse-shaped maleporophores are in XVIII or XVII about 0.17–0.25 body circumferences ventrally apart. In addition, there is always a slight twist at about midway of the spermathecal duct from where the slender, twisted diverticulum passed into. Finally, there are no genital markingsor papillae in male pore and spermathecal pore regions, instead of the presence ofa median, presetal genital marking at the midventral line on segments III, IV and V as in A. antefixus. As to Amynthas liaoi sp. nov., it is characterized by the constant presence of two horizontal rows of three to eight presetal and postsetal papillae in segment XVIII,and one horizontal row of about five postsetal papillae in segment IX. The ampulla shapeand size are also different between this new species and A. antefixus. The two Metaphire species are M. nanlingmontis sp. nov. and M. dadingmontis sp. nov. M. nanlingmontis sp. nov. appears to be related to M. jianfengensis (Quan, 1985). They have the same spermathecal pore number and position, and similar male pore copulatory chambers. However, M. nanlingmontis is much smaller in body size thanM. jianfengensis. In addition, there is a special ring-like swelling at the border between the duct and the chamber in the spermathecal diverticulum, and a mushroom-like accessory gland present beside the duct. M. dadingmontis sp. nov. appears to be closely related to M. nanlingmontis sp. nov. However, it is also easy to distinguish them from their different diverticulum shape and accessory genital glands in prostatic region. A comparison among the 10 similar Metaphire species with two pairs of spermathecae in VII and VIII has been made.
