  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.

Restriction of the Type Locality “Los Puentes”, Ecuador, for Several Species of Arachnida, Gastropoda and Plants

“Los Puentes” in northwestern Ecuador has been cited as the type locality for several spider, gastropod, and plant taxa. Yet, earlier works ambiguously described it as “near Quito,” leading to confusion about its location. By examining historical documents, maps, and an official decree, I verify that “Los Puentes” lies near Nanegalito, Pichincha province, on the northwestern slopes of the Western Cordillera of the Andes of Ecuador, at 1200–1500 m elevation. I formally restrict the type locality for multiple species, including Isomeria bourcieri lutea Cousin 1887 (Gastropoda: Labyrinthidae), Guestieria locardi Jousseaume 1887 (Gastropoda: Scolodontidae), Proserpinella cousini Jousseaume 1887 (Gastropoda: Proserpinellidae), Mesembrinis vesperus Jousseaume 1887 (Gastropoda: Achatinidae), Idiophthalma robusta Simon 1889 (Arachnida: Barychelidae), Eurypelma (Lasiodora) augusti Simon 1889 (Arachnida: Theraphosidae), Eurypelma (Lasiodora) vespertinus Simon 1889 (Arachnida: Theraphosidae), Asplundia nonoensis Harling 1958 (Pandanales: Cyclanthaceae), and Blakea eriocalyx Wurdack 1979 (Myrtales: Melastomataceae), ensuring taxonomic clarity.
