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 po...
Earthworms enrich the soil and protect the health of their ecological environment. Previous studies on these invertebrates determined their protein content, hormone secretions, medicinal value, and ecological habits, but their whole genomic sequence remains incomplete. We performed whole genome sequencing of Metaphire vulgaris (Chen, 1930), which b...
Amynthas triastriatus (Oligochaete: Megascolecidae) is a widely distributed endemic species in Southern China. To shed light on the population genetic diversity and to elucidate the population differentiation and dispersal of A. triastriatus, a population genetic structure study was undertaken based on samples from 35 locations collected from 2010...
The earthworm Amynthas morrisi (Beddard, 1892) is a cosmopolitan species. It is mainly distributed in the mainland of South China, and its genetic structures had never been concerned. The earthworm specimens were collected systematically in this study, hence 88 A. morrisi new records from 30 locations were discovered. The haplotype network analysis...
The earthworm Amynthas corticis (Kinberg, 1867) is a cosmopolitan earthworm species and is located in several areas in China, but its genetic diversity is still unknown. The genetic diversity, phylogenetic structure, and divergence time were analyzed in this study. The result shows that there are 20 haplotypes and four lineages in A. corticis, the...

The Hengduan Mountains (HMs), China, is a biodiversity hotspot that uplifted mainly between Late Miocene and Late Pliocene, the uplift movement might have a significant impact on the evolution of earthworms. Here, we investigated the species richness and the distribution of the earthworms in the HMs. A total of 170 species/subspecies belonging to f...

A total of 579 Megascolecidae species have been reported in China through 2017. Most belong to the genera Amynthas and Metaphire. The family’s rich diversity merits further investigation into its evolutionary history. The arc of research indicates that analysis based on taxonomical and molecular methods reveals the evolutionary history of the famil...
Two new species of earthworms belonging to the genus Amynthas are described from Guangxi Province, China: Amynthas crassitubus sp. nov. and Amynthas stabilis sp. nov. from Shiwan Mountain Nature Reserve. The two species have three pairs of spermathecal pores in 6/7–8/9, and belong to the sieboldi-group. COI barcode sequences support their status as...
Four new species belonging to genera Amyntha and Metaphire were discovered from an extensive area in southern China, covering the provinces Sichuan, Yunnan, Guizhou, Guangdong, Guangxi, Fujian, Hunan, Jiangxi and Anhui. The species are named Amynthas dispersus Sun & Qiu, sp. nov., Amynthas shanghangensis Sun & Qiu, sp. nov., Amynthas dentiformis Su...
Three new species of the genus Amynthas are described from Guangxi Province, China. They are named A. dissimilis sp. nov., A. anteporus sp. nov. and A. marsupiformis sp. nov. All of them have two pairs of spermathecal pores in 6/7–7/8, and belong to the tokioensis-group. Their morphological characteristics are compared to similar species in tokioen...
Our knowledge of the phylogeny of the earthworm genus Amynthas under the family Megascolecidae, which is comprised of a huge number of species, is very limited compared to the better-known and much smaller family Lumbricidae. In order to investigate the phylogenetic relationships among the species within the genus Amynthas, which is the largest gen...

The first three species could be assigned to the Amynthas sieboldi group and the last species could be assigned to the Amynthas aeruginosus group accor...
The Pheretima complex within the Megascolecidae family is a major earthworm group. Recently, the systematic status of the Pheretima complex based on morphology was challenged by molecular studies. In this study, we carry out the first comparative mitogenomic study in oligochaetes. The mitogenomes of 15 earthworm species were sequenced and compared...
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.

In the Chinese Hainan Island, Amynthas and Metaphire are two dominated pheretimoid earthworm species belonging to the family Megascolecidae. They differ from earthworms in the adjacent regions in their morphology and at the molecular level, which could have occurred due to the unique geography of Hainan Island. Hainan Island is made of two tectonic...
