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)

  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 remarkable new species of the genus Chilobrachys Karsch, 1892(Araneae: Theraphosidae) from Yunnan, China

Abstract

A new spider species of the genus Chilobrachys Karsch, 1892 of the family Theraphosidae Thorell, 1869is described from Yunnan, China: C. sherwoodae Lin & Li, sp. nov. based on both sexes. Photos and amorphological description of the new species are given. The type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS) in Beijing, China.

Etymology: The species is named after Miss Danni Sherwood, who kindly provided photographs of the types of other Indochina Chilobrachys, which enabled us to recognise the new species; noun (name) ingenitive case.
