  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 species of the lyrate curtain-web spider genus Trechona C. L. Koch, 1850 from South Brazil and the hitherto unknown female of T. excursora (Araneae: Dipluridae)

Abstract

A new species of the lyrate curtain-web spider genus Trechona C. L. Koch, 1850, Trechona minuana sp. nov., is described, based on males and females from Santa Catarina state, South Brazil. It is the first species of the genus from this Brazilian region. Additionally, we describe for the first time the female of Trechona excursora Pedroso, Miranda & Baptista, 2019 based on specimens from its type localities.
