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:

Marusik & Zonstein (2021): description of Raveniola ambardzumanyani from Armenia
Esyunin (2017) made available some specimen data collected by Dmitri Kharitonov, among this females of Dictyna ottoi from Georgia.
Ponomarev & Komarov (2015) provided lots of species records of spiders from South Ossetia, including some first species records for the Caucasus database here: Hahnia helveola, Pardosa consimilis, Pardosa inquilina, Neottiura suaveolens, Ozyptila spirembola.
All records of Ozyptila lugubris (Kroneberg, 1875) in the Caucasus are linked to Xysticus tuberosus (Thorell, 1875) now (see Marusik & Mikhailov, 2021).
Logunov & Ponomarev (2020) updated information on fossorial lycosids in the Caucasus, therefore Hogna bergsoei is of doubtful status and now listed on the Blacklist only. Records of Hogna/Lycosa alticeps actually belong to Karakumosa shmatkoi.
Information on records in Schmidt (1895) is corrected, e.g. information on Lycosa alticeps (see above) and the actual location of „Aresch“ mentioned. Also the PDF is finally added.
Prószyński (2017) removed Attulus vilis from synonymy with A. ammophilus and reported A. vilis from Armenia. Since both species are extremely similar to one another, especially the males, this raises the question of the species identity of the A. ammophilus records in the Caucasus. Until this is resolved in a revision of the Caucasian records, both „species“ are treated here under A. ammophilus.
Zarikian (2020) added a number of salticid species to the Checklist Armenia and one species to the Checklist Caucasus: Afraflacilla epiblemoides.
Mikhailov & Propistsova (2017) recorded a number of species from Armenia, among them a first record for the Caucasus: Pellenes arciger.
Dimitrov (2020) described and recorded Proislandiana beroni from Turkey and Armenia.
Tanasevitch et al. (2016) described two new species of linyphids from Adygea and Georgia: Asthenargus adygeicus and Maculoncus obscurus.
Ponomarev & Shmatko (2019) updated information on Zelotes species in the Caucasus
Ponomarev & Shmatko (2020) added new records for species in the genera Trachyzelotes and Marinarozelotes.
Khasayeva & Huseynov (2019) recorded a number of species from Azerbaijan, among them the first record of Pseudicius palaestinensis for the Caucasus.
Ponomarev et al. (2019): recorded Synaphosus shirin and Holocnemus pluchei for the first time in the Caucasus

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

The record of Zora spinimana in Lagodekhi by Otto & Japoshvili (2018) was erroneosly linked to Zoropsis spinimana. This is fixed now (thanks to Armen Seropian for pointing it out!)
Mikhailov (2016) added records of species which are now regarded as Micaria sociabilis and Micaria zonsteini.
Zamani et al. (2020) synonymized Araniella tbilisiensis (Mcheidze, 1997) with A. opisthographa and reported Neoscona theisi from Dagestan and Georgia.
Ponomarev et al. (2017) added 354 records of 218 species to the database. Additions to the Caucasus Checklist are Zelotes eugenei, Z. prishutovae, Z. tenuis, Erigonoplus spinifemuralis, Styloctetor compar, Aelurillus laniger, Heliophanus koktas, Ozyptila simplex and Zodarion rubidum.
13 records from Titova & Egorova (1978) (as cited from Ponomarev et al. (2017)

New Database Version 03.2020

*Amaurobius caucasicus* from Lagodekhi National Park

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

Marusik & Azarkina (2016) added new records of Xysticus spasskyi
Ponomarev et al. (2019) added 400+ records for spiders species in Dagestan, including first records for the Caucasus Ecoregion (Pholcus sogdianae, Phlegra lineata, Berlandina saraevi)
Marusik et al. (2020) added the new species Amaurobius caucasicus Marusik, Otto & Japoshvili 2020 from Lagodekhi National Park and a record of Amaurobius antipovae from Adler (Krasnodar)

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

Schreibe eine Antwort

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).

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!

Database Version 08.2017

Schreibe eine Antwort

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.

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:

Dunin (1982) on Dysdera concinna
Tanasevitch (1986) on two linyphiid species
Dunin & Mamedov (1992) on 127 species in an ecological study on spiders in cotton fields in Mugan Steppe (Azerbaijan)
Ovtsharenko et al. (1994) on Synaphosus palearcticus
Dunin (1998) with an ecological study on the altitudinal zonation of 259 species in NW Azerbaijan
Ovtsharenko et al. (1995) on Parasyrisca species from the North Caucasus
Logunov (1998) on Pseudeuophrys species

Ponomarev & Volkova (2013) with 154 records from the Abrau Peninsula in the NW Caucasus
Chaladze et al. (2014) calculated a first model of spider diversity in the Cauasus Ecoregion (meta study from the database, no new records)

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!
