Abstract

This paper describes two new species of earthworms belonging to the Amynthas morrisi-group from Hainan Island, China: Amynthas zonarius sp. nov. and Amynthas wuzhimontis sp. nov. Both have two pairs of spermathecal pores in 5/6-6/7, and simple intestinal caeca. Amynthas zonarius sp. nov. has a pad-like male porophore, with flat-topped tubercle surrounded by 5 skin folds distal half of the spermathecal diverticulum dilated into band-shaped seminal chamber. Amynthas wuzhimontis sp. nov. has a seminal chamber constricted into moniliform subchambers and a glandular pad-like elliptical male pore porophore surrounded by the tumid area. Partial COI sequences of the holotypes of the two new species have been submitted to GenBank as DNA barcodes to enable molecular species identification.

摘要

本文描述了来自中国海南岛的莫氏远盲蚓类群的两种新蚯蚓

环带远盲蚓新种（Amynthas zonarius sp. nov.）和五指山远盲蚓新种（Amynthas wuzhimontis sp. nov.）。两者在5/6 - 6/7节都有两对受精囊孔，且肠盲囊简单。环带远盲蚓新种有一个垫状雄孔器，其顶端扁平的瘤被5条皮肤褶包围，受精囊盲管远端一半扩张成带状精囊。五指山远盲蚓新种有一个收缩成念珠状子腔的精囊，以及一个被肿胀区域包围的腺状垫状椭圆形雄孔器。这两个新种的模式标本的部分细胞色素氧化酶亚基I（COI）序列已作为DNA条形码提交至GenBank，以实现分子物种鉴定。
