  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.

First DNA barcoding of Dysderidae (Araneae) from Kosovo, with new records and the description of a new species of Harpactea Bristowe, 1939

Abstract

New taxonomic and faunistic data on the dysderid spiders of Kosovo are presented, along with a survey of previous records. Harpactea dardanica Geci & Zamani sp. nov., belonging to the lepida species-group, is described as new to science based on male specimens collected in the Bjeshkët-e-Nemuna National Park, western Kosovo. Dysdera adriatica Kulczyński, 1897, Dy. lata Reuss, 1834, Dasumia kusceri (Kratochvíl, 1935), H. rubicunda (C.L. Koch, 1838), H. srednagora Dimitrov & Lazarov, 1999, and H. tenuiemboli Deltshev, 2011, as well as the genus Dasumia Thorell, 1875, are reported from Kosovo for the first time. Additional records are provided for Dy. longirostris Doblika, 1853 and H. lepida (C.L. Koch, 1838). DNA barcodes (partial sequences of the mitochondrial cytochrome c oxidase subunit 1 gene) were generated for all species. Photographic illustrations are provided for the newly described species, as well as for H. srednagora and H. tenuiemboli.
