Victora Tang and co-workers have recently published an extensive study describing a new genus and species from Xizang (Tibet), China.

Langxie feti Tang, Jia & Liu, 2023
The new species seems to be extremely abundant in the region.
I would like to compliment the authors for this work, which was completed despite of major challenges!
Abstract:
A new monotypic genus, Langxie gen. n., is described from Xizang (Tibet), China. The new genus shares an important morphological character with Afrolychas Kovařík, 2019: absence of external accessory denticles (EADs) along the sixth row of median denticles (MDs) on the pedipalp movable finger. Langxie gen. n. is different from Afrolychas in the following aspects: loss of EAD near the proximally enlarged MD within each row (i. e., loss of all EAD on the movable finger; this also distinguishes the new genus from other related genera in the “(Ananteris + Isometrus)” clade (Štundlová et al., 2022)), subaculear tubercle armed with or without a secondary tubercle dorsally, immaculate color pattern, more slender appendages and metasoma, and less sexually dimorphic pectines. Langxie gen. n. further differs from another geographically close genus, Himalayotityobuthus Lourenço, 1997, by the presence of highly developed pectinal fulcra (vs. absent in Himalayotityobuthus), six rows of MDs on the pedipalp movable finger (vs. 7–8 in Himalayotityobuthus) and five pairs of lateral ocelli (vs. 3 in Himalayotityobuthus). The new species, Langxie feti sp. n., is small and slender, exhibiting no obvious sexual dimorphism in pedipalp and metasoma, but the sexes are visibly different in the relative size of median ocelli and coarseness of carapacial granulation. Lattice microstructures are prominently developed on its cuticle.
