  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 HAHNIA (ARANEAE, HAHNIIDAE) FROM BULGARIA AND CRIMEAN PENINSULA CLOSE TO H. NAVA

A New Species of Hahnia (Araneae, Hahniidae) from Bulgaria and Crimean Peninsula close to H. nava. Indzhov, S. — Hahnia kovblyuki sp. n. is described from forest habitats in Western Bulgaria and compared to its closest species, H. nava (Blackwall, 1841), using morphology and simple morphometry. Previous records of H. nava from Crimea are formally re-assigned to H. kovblyuki sp. n., and issues in the taxonomy of the Hahnia nava complex are briefly discussed.
