  Tracking a Tarantula Diversification in a Neotropical Open Biome ABSTRACT Aim To investigate the lineages diversification of Dolichothele exilis in the Caatinga biome and to infer geological and climatic drivers of diversification in this region. Location Caatinga, Northeast of Brazil. Taxon Dolichothele exilis (Araneae: Theraphosidae). Methods We used 96 individuals for genomic sequencing (GBS sequencing) and 39 individuals for COI mitochondrial marker sequencing. Population structure was inferred using STRUCTURE and SNMF approaches, and genetic diversity and diversification indices were calculated. A maximum likelihood phylogenetic tree was constructed with SNPs data and a Bayesian tree with mitochondrial data. To explore the demographic history, DIYABC was used, with a Random Forest (RF) classifier. Finally, we constructed Habitat Suitability models using five different algorithms to investigate present and past potential distributions. Results Analyses based on SNPs data an...

Abstract

A survey of ground spiders of the genus Synaphosus Platnick & Shadab, 1980 (Gnaphosidae) from Azerbaijan, including five species, is presented. Among them, S. nakhchivanicus sp. nov. is described based on a male specimen collected in the Julfa District. In addition, S. syntheticus (Chamberlin, 1924) is reported from the Caucasus for the first time.
