Introduction
I worked for 15 years on faunistic and taxonomic questions concerning spiders in the Caucasus Ecoregion, e.g. as the Regional Coordinator in "CaBOL - Caucasus Barcode of Life" in 2020 and 2021 at Ilia State University. Since summer 2021 I focus again on the spider work as an associated researcher in the CaBOL Project. https://ggbc.eu/ -- http://stefan-otto-spiders.de/ -- http://caucasus-spiders.info/

Article
Full-text available
A new species, Amaurobius caucasicus sp. n., is described based on the holotype male and two male paratypes from Eastern Georgia. A similar species, A. hercegovinensis Kulczyński, 1915, known only from the original description is redescribed. The taxonomic status of Amaurobius species considered as nomina dubia and species described outside the Hol...
Article
In the largest systematic spider collection effort in a single location in the Caucasus Ecoregion, across several altitudinal zones and throughout the entire vegetation period of one year, 426 juvenile and 359 adult spiders belonging to 69 species from 48 genera and 19 families were collected in the Lagodekhi Reserve, Georgia, in 2014, using Malais...

Ein Nachruf auf Hans Betten (1915-1957), Zoologe und Schullehrer mit Interesse an Spinnen. Obwohl er keine eigenen Forschungsarbeiten an Spinnen veröffentlicht hat, trug er durch eigene Beobachtungen an Spinnen in den 1950er Jahren zu den Linyphiidenstudien Hermann Wiehles bei, der schließlich Theridion betteni Wiehle, 1960 posthum nach Hans Betten...

An illustrated description of Clubiona caucasica sp. n., which is closely related to C. caerulescens L. Koch, 1867 is provided. The new species is found in the Caucasus (Russia, Georgia, Azerbaijan, Armenia) and in Turkey (one locality). http://www.zoobank.org/urn:lsid:zoobank.org:pub:4C8851E2-CBBC-42E6-8600-585E757C9043
Article

The new species, Incestophantes shetekaurii sp.n., is described from the high mountains of the Caucasus Major (Georgia, 2500 m a.s.l.). This new species is similar to the European-West Siberian I. crucifer (Menge, 1866) and to the Crimean I. australis Gnelitsa, 2009, but differs noticeably in the details of the genitalia in both sexes. The generic...

The Caucasian Spiders Database aims at containing all records (published occurrences) of spiders (Araneae) in the Caucasus Ecoregion (the rayons Krasnodar and Stavropol in Russia, Adygea, Karachay-Cherkessia, Kabardino-Balkaria, North Osetia, Ingushetia, Chechnya, Dagestan, Georgia (including Abkhazia and South Osetia), Armenia, Azerbaijan). New fe...
Data
This is the most recent database update (10 Oct. 2013), the basis of most information on http://caucasus-spiders.info/. It includes 10997 original records, 41634 cited records of 3072 species (1107 species in the Caucasus Ecoregion) based on the occurence data of 241 publications.

The poorly known wolf spider Alopecosa charitonovi Mcheidze, 1997 is redescribed and a new combination Geolycosa charitonovi (Mcheidze, 1997) n. comb. ex Alopecosa is proposed. The male of this species is described for the first time. Geolycosa charitonovi is distributed across the whole Caucasus Major from Krasnodar Province in Russia to Azerbaija...

The canopy spiders of the floodplain forest in Leipzig have become a focus of ecological studies in recent years. In 2006 we sampled 30 tree canopies in the ‘Burgaue’ nature reserve with pyrethrum knock-down fogging, recording 502 adult spiders belonging to 48 species and 11 families. Based on these data and the results of a previous fogging study,...
Data
During my (S.O.) stay in Georgia between March and July, 2009, I spent a significant amount of time at the arachnological collection of the Janashia Museum. There I wrote a preliminary catalog of the determined material (approx. 1000 vials) in the collection and tried to find valuable comparative material for my future field studies in Georgia. The...

Dispersal of two moderately venomous spiders Cheiracanthium mildei and C. punctorium in Saxony and Brandenburg (Araneae: Miturgidae). In the summers of 2006 and 2007 presumed bites of Cheiracanthium spiders triggered mass hysteria in Austria and some regions of Germany, including northern Saxonia. Here we report the first records of Cheiracanthium...

Spider communities of tree-canopies in primary forest sanctuaries and forest plantations of the Białowieża Forest were sampled using insecticidal knockdown fogging. The communities showed the typical guild-, family-and species-composition of European forests with a dominance of web spiders and woodland-canopy spiders (e. g. Diaea dorsata, Anyphaena...

For the first time the spider species Theridion palmgreni Marusik & Tsellarius, 1986 is recorded in Poland in the Białowieża Forest. Furthermore, previously unpublished data for the species from Finland, Russia and Estonia are included. The female is figured. History, distribution and phenology of this species with an Euro-Siberian boreal range is...

Is there an influence of the red wood ant Formica po[yctena FOERSTER on species composition and structure of spider communities of oak trees? We collected spider communities of oak trees in a Bavarian forest (Germany) by insecticidal knockdown fogging and investigated how communities changed on trees where predacious Formica polyctena ants were dom...

We set 7 Malaise traps in 7 different altitudes and collected material during whole vegetation season every 10 days. The altitude range was from 666 to 2559 m. Material is under identification. At the moment only Encyrtidae family is completely identified and we have almost 120 species, with 45 new species records for Georgia and 24 for Transcaucasus. 7 species are new to science. From already identified 9 genera of Eulophids 33 species are new to Georgia and 32 for Transcaucasus. This is just tiny information to give you idea what a high and interesting diversity is in this reserve.
