  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.

A checklist of spiders from superfamily Lycosoidea in India: A taxonomic overview emphasizing precinctive/ endemic species

Abstract

The current checklist documents 448 species from 81 genera & 6 families within the Lycosoidea group in India. There is a significant disparity in the male-to-female ratio, with 212 males compared to 415 females described. Among these six families, two are represented by more than 100 species: Thomisidae, with 41 genera & 177 species, & Lycosidae, with 20 genera & 132 species. Precinctive/ endemic spiders from the 06 families of the Lycosoidea group from India comprise of 301 species from 31 genera, thus, 38.27% of genera & 67.18% of species are endemic among the known spider species.
