  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.

Extending the distribution of Latrodectus corallinus Abalos, 1980 (Araneae: Theridiidae) in South America: first record for Brazil

Abstract

The widow spider Latrodectus corallinus Abalos, 1980, a species reported previously only for Argentina, was recorded in the central-western region of Brazil, associated with sandstone caves in São José do Rio Claro, in the State of Mato Grosso, and in open areas of the Pantanal (Miranda) and the Brazilian savanna in Bodoquena, in the State of Mato Grosso do Sul.
