  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 new Centruroides species and first record of C. tapachulaensis Hoffmann, 1932 (Scorpiones: Buthidae) from Honduras

Abstract

A new species of striped bark scorpions, Centruroides lenca sp. n. is described, based on both sexes, from the Pacayita Volcano Biological Reserve (2,385 m a. s. l.), Ocotepeque Department, in the southwestern Honduras. By its general pattern, the new species resembles C. thorellii (Kraepelin, 1891), from which it clearly differs by having stronger and very darker pedipalp chelae, minute subaculear tubercle and basal pectinal plate with a large central pit in the female, among other diagnostic characters. Also, Centruroides tapachulaensis Hoffmann, 1932 is recorded for the first time from Honduras, on the basis of two observed or collected specimens in the Ocotepeque Department. There are currently 12 species of Centruroides known from Honduras, of which three are known only from this Central American country (two other endemic species are C. terueli Armas & Cubas-Rodríguez, 2023, from Guanaja Island, Islas de la Bahía Archipelago, and C. hirsuticauda Teruel, 2011, from Comayagua and Yoro Departments).
