  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...

Redescription of Damastes leo (Simon, 1903), comb. nov. (Araneae, Sparassidae) from Madagascar with first description of the male

Abstract

Damastes leo (Simon, 1903), comb. nov. (ex Megaloremmius) female is redescribed and the male is described for the first time. The species is endemic to Madagascar, and its range appears to be limited to remnants of the rainforest. The first COI record for the species is presented, and its distribution is analysed in detail using iNaturalist data.
