Three new earthworm species of the genus Amynthas Kinberg, 1867 were found in Guangxi Zhuang Autonomous Region, China: Amynthas huapingensis sp. nov., Amynthas retentus sp. nov. and Amynthas linguiensis sp. nov. Amynthas huapingensis sp. nov. belongs to Amynthas corticis-group characterized by having four pairs of spermathecal pores in 5/68/9; Amynthas retentus sp. nov., without spermathecal pores, belongs to Amynthas illotus-group; Amynthas huapingensis sp. nov. and Amynthas retentus sp. nov. have similar characteristics of male porophores medially surrounded by 23 genital papillae in a pulvinate pad within the male pore area. Amynthas linguiensis sp. nov. has variable spermathecal pores, three pairs in 6/78/9 or four pairs in 5/68/9. And its male pores each on the center of a large elliptical glandular porophore which extends from 1/4xvii to 1/4xix. The morphological comparison and COI gene data of these three new species and their similar species are given in this paper.
在中国广西壮族自治区发现了三个新的蚓科环节动物属 Amynthas Kinberg,1867 种:华美 Amynthas huapingensis sp. nov.、保留 Amynthas retentus sp. nov. 和灵川 Amynthas linguiensis sp. nov.。华美 Amynthas huapingensis sp. nov. 属于 Amynthas corticis 组,其特征为在 5/68/9 处有四对受精囊孔;无受精囊孔的保留 Amynthas retentus sp. nov. 属于 Amynthas illotus 组;华美 Amynthas huapingensis sp. nov. 和保留 Amynthas retentus sp. nov. 具有雄性孔区中 23 个生殖乳突被盘状垫中部环绕的相似特征。灵川 Amynthas linguiensis sp. nov. 的受精囊孔数目可变,在 6/78/9 处有三对或在 5/68/9 处有四对。其雄性孔位于每个大椭圆形腺状孔的中心,该孔从 1/4xvii 延伸到 1/4xix。本文对这三个新种及其相似种进行了形态比较和 COI 基因数据分析。
