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

Three new species of the giant vinegaroon genus Mastigoproctus (Thelyphonida: Thelyphonidae) from Mexico

Abstract

The giant vinegaroons of the genus MastigoproctusPocock, 1894 have been the subject of recent investigations aimed at elucidating relationships between their species and their validity. In particular, new data have revealed the presence of new species as well as revalidated species that were previously considered as synonyms of Mastigoproctus giganteus (Lucas, 1835). The genus occurs in southern USA, Mexico and South America. In this paper, we describe three additional new species from Mexico: M. franckei Barrales-Alcalá, sp. nov. from Xilitla, San Luis Potosí, M. xetame Barrales-Alcalá & Francke, sp. nov. from the highlands of Jalisco and M. yalchanchak Barrales-Alcalá & Francke, sp. nov. from La Esperanza, Chiapas. The present contribution raises the diversity of the order Thelyphonida in Mexico to 10 species.
