  A new Cataleptoneta species (Araneae, Leptonetidae) from sulfidic caves in Greece and Albania Abstract A new species of the genus Cataleptoneta Denis, 1955, Cataleptoneta sulfur sp. nov ., is described from caves in the Vromoner Canyon (Sarandaporo River Valley), on the Greek–Albanian border (northwestern Greece and southern Albania), on the basis of both sexes. Drawings, scanning electron micrographs, and digital images of diagnostic features are presented. Analysis of COI mitochondrial barcode sequences confirmed the species distinction from all the other sequences. Within the species two separate lineages, unique to each cave were found. The genus Cataleptoneta is not monophyletic as now circumscribed and confirmed also by the phylogenetic analysis of the sequences.

A new African species of the genus Leiurus Ehrenberg, 1828 from Mali (Scorpiones: Buthidae)

Abstract


A new species of Leiurus Ehrenberg, 1828 is described on the basis of one male specimen collected in the mountain system of Adrar des Iforas, Cercle of Kidal, in Mali. The new species, Leiurus tamajeq sp. n. is most certainly associated to Leiurus hoggarensis, described from the Hoggar mountain system in Algeria, both species presenting an almost parapatric geographic distribution. Nevertheless, these closed related mountain systems have been isolated during past palaeoclimatic vicissitudes leading to possible differentiation processes. The two species can be distinguished by a number of morphological characters which clearly suggest that the new species population is distinct from the one found in the Hoggar mountain system. Differences are noticeable notably for morphometric values as well as the relative position of several trichobothria. As for L. hoggarensis, the new species seems to inhabit a more mesic zone when compared to the central compartment of the Saharan desert and, apparently, do not present characteristics of a psamophilic species and may be considered as a lithophilic species.
