Abstract

This study describes three new earthworm species, namely, Amynthas yichunensis Sun & Jiang, sp. nov., A. huizhouensis Sun & Jiang, sp. nov., and A. shangraoensis Sun & Jiang, sp. nov. A. yichunensis sp. nov. exhibits variability in the number and position of spermathecal pores, with 0, 1, or 2 pairs located at intersegmental furrow 8/9 or spanning segments 7/8–8/9. A. huizhouensis sp. nov. possesses three pairs of spermathecal pores, located at intersegmental furrows 5/6–7/8, similar to other species within the A. gracilis group. A. shangraoensis sp. nov. features four pairs of spermathecal pores, which places it within the A. corticis group, with the pores located at intersegmental furrows 5/6–8/9. The genetic barcodes for the newly identified species have been submitted to the GenBank database.
