  Integrative taxonomy of the genus Nesticus in central Japan, with the description of a new species and redescriptions of N. echigonus and N. gondai (Araneae, Nesticidae) Abstract Species of the genus Nesticus ( Araneae , Nesticidae ) in central Japan are revised based on morphological and molecular analyses of specimens collected from Niigata and Gunma Prefectures. Among them, a putative undescribed species was discovered having clearly distinguishable morphological characters from other known species in the same area. A phylogenetic analysis based on the mitochondrial COI gene was carried out using a maximum-likelihood method to confirm its distinctiveness. The new species, Nesticus yamabushi sp. nov ., is described based on specimens of both sexes. Furthermore, we provide detailed redescriptions of two other closely related species, N. echigonus and N. gondai , to address the lack of information in their original descriptions and facilitate future identifications.

New records of the camel spider Antillotrecha iviei Armas, 2002 from Anguilla, Lesser Antilles (Solifugae: Ammotrechidae)

Abstract
Antillotrecha iviei Armas, 2002, previously thought to be restricted to Sombrero Island, is confirmed to be present on Anguilla Island, based on material of both sexes collected by the senior author in early 2025. Adults of both sexes are described and illustrated, with comparison against previously reported material.
