Also, a number of genera have been moved to other families, including: Argyroneta → Dictynidae; Cryphoeca, Tuberta → Cybaeidae; Mastigusa → Hahniidae; Pireneitega → Agelenidae; Cheiracanthium → Cheiracanthiidae; Zora → Miturgidae; Cetonana, Orthobula, Trachelas → Trachelidae

Upcoming updates are planned to include newly compiled distribution maps and new occurrence data (records) from recently published articles about spiders in the Caucasus. If you know of any publication not yet included in the database, let me know!
Version 8.2018 of the Caucasian Spiders Database now contains the records of a number of old and new publications:
2. Otto & Japoshvili (2018) updated the checklist of spiders in Lagodekhi,
4. Dunin (1988) recorded a number of mygalomorphic spiders,
5. Spassky (1937) described a mygalomorphic spider species from the Caucaus.
8. All records of Hyptiotes gerhardti revalidated and all records of H. paradoxus and H. flavidus from NW-coast of the Black Sea attributed to this species, cf. Wiehle (1964), Wunderlich (2008) and Wunderlich (2017),
9. One record from a cave survey in Abkhazia by Ljovushkin (1966),
There is a new link page in Publications>Links. Did I miss any relevant pages or projects on Caucasian spiders, insects and other biodiversity? Any study groups working on Caucasian invertebrates? Let me know!
Starting now in August 2017, the database will be updated in shorter intervalls with versionnumbers giving month and year, e.g. 08.2017. This should allow (and motivate) me to work on the database more often, not only in a bulk action every two years or so.
Version 08.2017 includes the newly described Clubiona caucasica Mikhailov & Otto, 2017 in the checklist Caucasus and excludes Clubiona caerulescens L. Koch, 1867, which can easily be confused with C. caucasica and has not yet actually been recorded from the Caucasus.

Version 1.4.3 of the Caucasian Spider Database includes 13321 records of 1107 spider species, destilling the information distributed across 275 publications with occurrence data of spiders in the Caucaus Ecoregion.
Citation: Otto, S. (2015): Caucasian Spiders. A faunistic database on the spiders of the Caucasus. Version 1.4.3 Internet: http://caucasus-spiders.info/
New features on these pages include:
- A Commented Checklist of the Spider Species (Araneae) in the Caucasus Ecoregion (also available as PDF),
- Redesigned species datasheets with new record maps, information on altitudinal distribution and abundance status,
- The new Genus pages listing all species within a genus according to their abundance and with links to the pages of Araneae – Spiders of Europe. This feature should make determination somewhat easier,
- A record density plot (see above) showing relatively well visited regions and regions with few or no spider records at all (gray and white areas in the plot). More information on spider diversity patterns is given in the pages on landscape & habitat diversity and species diversity patterns.
New content in the database includes:
- Utochkin (1968) with descriptions of three species: Xysticus caspicus, X. spasskyi (= X. umbrinus), X. ukrainicus.

The records of some more publications are now in the database, raising the total number of original records in the database to 12119. Now, 1110 species are in the Checklist Caucasus and 27 species are in the newly introduced Blacklist Caucasus (details see below).

Next to database updates, a number of changes aim at increasing accessibility of the content:
The Checklist Caucasus now contains only valid species with undoubtful records. Therefore, it is called: Critical and Commented Checklist of Spiders (Araneae) in the Caucasus Ecoregion (link).
In order to maximize availability of data and to facilitate accessibility to all – even doubtful or false records existing in the literature – a Blacklist Caucasus (link) is introduced and situated below the actual checklist – listing those species, which due to doubtful records in the Caucasus or invalid taxonomic status should not be part of the checklist sensu stricto. This blacklist can, however, be of interest to taxonomists when in search of literature sources concerning such questionable species or misidentifications.
Furthermore, all entries on the the publications page now have links to BibTeX citations (I am still working on PDF uploads) and all locations have been checked for double entries.
So, enjoy browsing!
The well-known rapid northward range expansion of this species in the last decades was attributed by the authors to genetic admixture of cold-adaptation alleles from East Asian populations.
Kovblyuk et al. (2013) described Pireneitega ovtchinnikovi and the male of P. spasskyi (Charitonov, 1946). Both species are vicarious species: P. ovtchinnikovi in the Western Caucasus Major and P. spasskyi in the Eastern Caucasus Major. The authors also identified all specimens of P. segestriformis (Dufour, 1820) from the Caucasus to be misidentified specimens of P. ovtchinnikovi.
With these updates, the database now runs as Version 1.4.1 (see details).
Starting today, Caucasian Spiders runs under version number 1.4. New features implemented since the last version include:
- increased data basis (now almost 11.000 species records of 1107 species from 241 publications),
- downloadable file with the database (see FAQ),
- new Country and Region Checklists,
- new Species Datasheets with updated OSM record maps, record lists and links to the determination data on Araneae – Spiders of Europe,
- new Location Pages with geoinformation and links to geonames.org,
- new Publications Page with BibTeX and PDF links,
- new FAQ page,
- attribution of the Open Database License (ODbL) to the database and its contents (see FAQ),
- and a new WordPress frontend.
Enjoy browsing! Feedback and constructive suggestions are always welcome!

In cooperation with Daniel Gloor the links between the species datasheets and determination pages on Araneae – Spiders of Europe are now updated for all valid species (sensu Platnick Catalog) in the Checklist Caucasus.
The distribution maps on Araneae – Spiders of Europe are now also updated based on the CaucSpiders Database.
