Three new earthworm species are described from South China, namely Amynthas rusticanus sp. nov., Amynthas scaberulus sp. nov., and Amynthas yuanjiangensis sp. nov. They are widely distributed in South China, and be polymorphic in reproductive organs. Of three new species, A. rusticanus sp. nov. is a small species with three pairs of spermathecal pores in 5/6-7/8 or two pairs of spermathecal pores in 5/6-6/7; it has developed prostate glands in XVI-XX. A. scaberulus sp. nov. is a medium-sized species with two pairs of spermathecal pores in 7/8-8/9; the lower edge of each spermathecal pore forms a tiny papilla, and the prostate glands are either degenerated or developed. A. yuanjiangensis sp. nov. is a medium-sized species with four pairs of spermathecal pores in 5/6-8/9 and has degenerated or developed prostate glands. Barcode data for each species (partial sequence of mitochondrial cytochrome c oxidase subunit I) are provided as well.

The function of insect external genitalia has played a significant role in exploring insect mating mechanisms and male fertilization strategies. However, due to the privacy of genital coupling, insect copulatory mechanisms have only been investigated in a few insect groups. In this study, we observed the mating behavior using freeze-fixated pairs in copula to reveal the copulatory mechanism of the longhorn beetle (Pascoe, 1871).
