  New considerations on the species of the genus Bothriurus Peters (Scorpiones: Bothriuridae) described or cited from the state of Paraná, Brazil and description of a new species Abstract A new species, Bothriurus trifinium sp. n. is described from an area of Riparian wet-forests in the Northwest of the state of Paraná in Brazil. The new species can be associated with other species previously described from the nearby regions of Paraná but also from Mato Grosso do Sul and Paraguay. The description of this new species attests once again about the existence of micro-endemic populations within different groups of Bothriurus. Comments are also proposed on the taxonomic status of some previously described species, with one species revalidated and some synonymies suggested. Wilson R. Lourenço, Lucienne Wilmé, Éric Ythier.

Four new species of dragon pseudoscorpions (Pseudoscorpiones: Pseudotyrannochthoniidae: Spelaeochthonius) from caves in South Korea revealed by integrative taxonomy

Abstract

Karst research in Korea is still in its infancy and the invertebrate fauna of subterranean systems across the country is poorly known. One of the very diverse lineages in caves across Korea, the pseudoscorpions, are almost undocumented although they represent stunning examples of cave adaptations and troglomorphism. In this study, we provide a phylogenetic hypothesis for the pseudoscorpion Spelaeochthonius Morikawa, 1954 (Pseudoscorpiones: Pseudotyrannochthoniidae) in South Korea; a genus that exclusively occurs in caves across China, Japan and the Korean Peninsula. We report seven species of which four are newly described and illustrated based on molecular, distributional and morphological data: Spelaeochthonius dugigulensis sp. nov., S. geumgulensis sp. nov., S. magwihalmigulensis sp. nov. and S. yamigulensis sp. nov. All species are strongly cave-adapted and known from a single cave or karst system only, emphasizing the need to implement conservation strategies for Korean karst systems and their fauna.
