  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.

The genome sequence of the snake-back spider, Segestria senoculata (Linnaeus, 1758) (Araneae: Segestriidae)

Abstract

We present a genome assembly from an individual female Segestria senoculata (snake-back spider; Arthropoda; Arachnida; Araneae; Segestriidae). The assembly contains two haplotypes with total lengths of 3 804.19 megabases and 3 893.16 megabases. Most of haplotype 1 (95.27%) is scaffolded into 8 chromosomal pseudomolecules. Most of haplotype 2 (93.96%) is scaffolded into 8 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 14.73 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
