New Database Version 02.2022

After about one and a half years it is about time for a new database update. Here it is!

A new feature in the checklists is the possibility to call checklists for certain regions and not only countries, e.g. Abkhazia, North Caucasus and South Ossetia now. Let me know if you want to see more specific regions or areas there, like protected areas for example: Lagodekhi National Park. Also, country and region checklists are now structured just as the Caucasus Checklist, meaning the checklist includes only species with verified status and a Blacklist below with the species of doubtful status.

Other changes include fixed mistakes, e.g. correctly linking Microdipoena jobi to Mysmenidae and updated taxonomy (e.g. in Agelescape, Persiscape). Thanks to Theo Blick, Yuri Marusik, Dmitri Logunov and others for pointing this out to me. It helps a lot!

As always: Please keep informing me about newly published or older literature which needs to be included in the database and point out any mistakes you found. I appreciate it very much!

The following updates to species records have been made in version 02.2022:

New Database Version 10.2020

The database has been updated. Please keep sending new papers and information on spider records in the Caucasus!

New Database Version 03.2020

Amaurobius caucasicus from Lagodekhi National Park

New records from several publications have been added to the database …

The distribution maps for each species have been slightly improved, e. g. the diagram displaying the altitudinal distribution now displays all record points. This should make the statistics more comprehensible. R programming is fun!

As always, please send me citations or even better, PDF files, of publications which need to be added to the database!

All the best, Stefan

New Database Version 09.2019

In this update I reviewed all 1100+ species in the Caucasus Checklist and updated some 50+ links to and from araneae.unibe (with the help of Daniel Gloor!).

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!

New Database Version 8.2018

All distribution maps are updated in Version 8.2018.

Version 8.2018 of the Caucasian Spiders Database now contains the records of a number of old and new publications:

1. Zonstein et al. (2018) revised the genus Raveniola in the Caucasus,

2. Otto & Japoshvili (2018) updated the checklist of spiders in Lagodekhi,

3. Shafaie et al. (2018): added a number of records for Pardosa colchica and P. pontica in Azerbaijan,

4. Dunin (1988) recorded a number of mygalomorphic spiders,

5. Spassky (1937) described a mygalomorphic spider species from the Caucaus.

6. A number of species of Dictynidae were studied by Marusik et al. (2015), Marusik & Koponen (2017) and Marusik et al. (2017),

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),

10. Some taxonomic changes, e.g. in the families Salticidae (e.g. genera Sittiflor, Sittipub etc.) and in Thomisidae (genus Bassaniana).

Database Version 08.2017

3097Starting 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.

Database Update (Version 1.4.2)


Spider diversity model for the Caucasus Ecoregion (Chaladze et al. 2014)

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).

List of new record data in database version 1.4.2:

You can find a link to the dump of the SQL database on the FAQ page.

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!

Large Database Update

2012_AbdurakhmanovEtAl_DagestanCoverSmallAbdurakhmanov et al. (2012) presented a substantial update of spider records in the Caucasus: 1371 records – adding 116 species to the list of 243 species in the Checklist Dagestan as well as adding 87 species to the North Caucasus Checklist and 31 species to the Checklist Caucasus, which now lists 1107 species from 10997 records in this Ecoregion!

In total, Abdurakhmanov et al. (2012) added 83 original records and cited many more records from Abdurakhmanov & Alieva (2011: 353 records), Ponomarev et al. (2011a: 237 records),  Ponomarev et al. (2008: 217 records), Ponomarev et al. (2011b: 188 records) and several other sources.
