  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...

Four new spider species of the Pholcus phungiformes species group (Araneae, Pholcidae) from South Korea

Abstract

Four new spider species of the genus Pholcus Walckenaer, 1805, Pholcus baegamsan sp. nov., Pholcus hongcheon sp. nov., Pholcus namhae sp. nov., and Pholcus yeongcheon sp. nov. belonging to the P. phungiformes species group in the family Pholcidae C. L. Koch, 1850, are newly described from South Korea. The new species presented here were hand-collected from rocky areas, such as rock walls and beneath rocks, in mountainous mixed forests.
