  First insular record and DNA barcoding of Euscorpius vailatii Tropea & Fet, 2015 from Trizonia Island (Fokida, Greece) Abstract Euscorpius vailatii Tropea & Fet, 2015 (Scorpiones: Euscorpiidae), originally described from Aitoloakarnania and Fokida (Greece), is herein reported from Trizonia Island in the Gulf of Corinth, representing the first insular record for the species. The examined specimens are consistent with the diagnostic morphology of E. vailatii . The first molecular data for the species are provided, based on both mainland and insular populations. Comparative analyses further highlight the distinctiveness of E. vailatii from geographically close congeners, while phylogenetic results indicate a sister-taxon relationship with E. erymanthius , supporting a Quaternary biogeographic history shaped by the evolution of the Gulf of Corinth system.

The genome sequence of the house spider, Eratigena atrica (C.L.Koch, 1843) (Araneae: Agelenidae)

Abstract

We present a genome assembly from a male specimen of Eratigena atrica (house spider; Arthropoda; Arachnida; Araneae; Agelenidae). The genome sequence has a total length of 4 947.42 megabases. Most of the assembly (98.73%) is scaffolded into 22 chromosomal pseudomolecules, including the X1 and X2 sex chromosomes. The mitochondrial genome was also assembled, with a length of 14.25 kilobases.
