Three new species of the primitively segmented spider genus Songthela (Araneae, Mesothelae) from Guizhou Province, China.

We diagnose and describe three new species of the primitively segmented spider genus Songthela from Guizhou Province, China, based on morphological characters and molecular data: S. liui sp. nov. (♂♀), S. tianzhu sp. nov. (♂♀), and S. yuping sp. nov. (♂♀). We provide the genetic distances within and among the three new species based on the DNA barcode gene, cytochrome c oxidase subunit I (COI) to support our descriptions. We also provide the COI GenBank accession codes for the three new species for future identification.
