Spider Cytogenetic Database

The Spider Cytogenetic Database

Current version: 13.5 (Feb 28, 2025)

Douglas Araujo, Marielle Cristina Schneider, Emygdio Paula-Neto and Doralice Maria Cella

In this site, there is a compilation of all cytogenetic data published on spiders (885 spider species of the 52.774 taxonomically described), considering only papers published in scientific journals and not abstracts presented on scientific meetings, thesis or other materials of restrict access. This compilation includes the species names, according to the World Spider Catalog, version 26 (WSC, 2025), accessed on Feb 28, 2025.

The site will be revised every 6 months (in February and August) to add new chromosomal data available on literature and changes in spider taxonomy.
