New data on Wangaraneus Mi, Wang & Li, 2024 (Araneae, Araneidae), with descriptions of two new species from Xizang, China

New data on Wangaraneus Mi, Wang & Li, 2024 are provided based on morphological examination and mitochondrial cytochrome c oxidase subunit I (COI) sequencing. Two new species from Xizang, China, W. delicatus Mi & Wang, sp. nov . and Wangaraneus fencha Mi & Wang, sp. nov ., are described and illustrated based on both sexes. In addition, two new combinations are proposed and established: W. cruciformis (Yin, Peng & Wang, 1994), comb. nov ., transferred from Singa C.L. Koch, 1836, and W. quadrituberculatus (Roy, Sen, Saha & Raychaudhuri, 2014), comb. nov ., transferred from Chorizopes O. Pickard-Cambridge, 1871. Wangaraneus zioni (Mi, Li & Pham, 2023), syn. nov . is synonymized with W. cruciformis . The newly described species are diagnosed based on detailed comparisons of somatic morphology and copulatory organs with similar congeneric species. Their placement within Wangaraneus is further supported by COI sequence evidence. An identification key to the known species (except W. quadrituberculatus ) is provided.
