  Remarkable micro-endemism and high congeneric richness: eight new cave-restricted species of Pseudochthonius Balzan, 1892 (Pseudoscorpiones, Chthoniidae) from the Brazilian semi-arid Abstract Eight new species of pseudoscorpions belonging to the genus Pseudochthonius Balzan, 1892 are described from the semi-arid region of Brazil. Comprehensive morphological descriptions, diagnostic characters, detailed illustrations, and ecological remarks of the habitats are provided for Pseudochthonius celestialis sp. nov., P. caritas sp. nov., P. patientia sp. nov., P. temperantia sp. nov., P. diligentia sp. nov., P. castitas sp. nov., P. humilitas sp. nov., and P. benignitas sp. nov. In addition, we present a brief discussion of the potential factors underlying the remarkable congeneric species richness observed in this geographically restricted region, as well as the principal threats faced by these species. These findings underscore the importance of conserving caves in order to pr...

A new species of the genus Selenocosmia Ausserer, 1871 (Araneae: Theraphosidae) from the karst landscapes of Meghalaya, India

Abstract

We describe a new species: Selenocosmia meghalayensis sp. nov. from East Khasi Hills, Meghalaya, north eastern India, based on three female specimens. The new species is diagnosed by a unique combination of morphological characters, with particular emphasis on the structure of the spermathecae, as well as somatic characters including coloration, setation, and morphometrics. Detailed descriptions and measurements, are provided. Notes on habitat and distribution map are included.
