Herein, three new species are described, all from Yunnan Province, China: Amynthas hiatus sp. nov., Amynthas recavus sp. nov. and Metaphire daliensis sp. nov. Amynthas hiatus sp. nov. belongs to the Amynthas aeruginosus-group, A. recavus sp. nov. belongs to the Amynthas corticis-group and M. daliensis sp. nov. belongs to Metaphire insulana-group. Amynthas hiatus sp. nov. and M. daliensis sp. nov. have two pairs of spermathecal pores in 7/8-8/9, A. recavus sp. nov. has four pairs of spermathecal pores in 5/6-8/9. The male pores of A. hiatus sp. nov. are 1/3 circumference apart ventrally and each on top of a large, raised pulvinate pad; the male pores of A. recavus sp. nov. are 2/5 circumference apart ventrally and each on top of a raised, elliptic, collapse-topped porophore; the male pores of M. daliensis sp. nov. are 2/5 circumference apart ventrally and in the oval copulatory chambers. In this paper, the anatomical and morphological characters of these three species are described. We also sequenced COI and 12S gene fragments in order to provide an analysis of K2P distances and a neighbour-joining tree.
