Otto & Japoshvili (2018): The spiders (Arachnida: Araneae) of the Lagodekhi Reserve, Georgia: faunistic results of a transect study and an updated checklist
Abstract: 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 Malaise traps on a transect with seven study plots between 666 and 2559 m in the montane, subalpine and alpine vegetation zones. Phoroncidia pilula (Karsch, 1879) is recorded in the Western Palaearctic for the first time. Thirty-eight species are recorded in the Lagodekhi Reserve for the first time, raising the number of spider species of this reserve to 202 species, five additions are first records for the Caucasus Ecoregion and ten species are first records for Georgia. Diagnostic drawings and analyses are provided for 13 species, e.g. Megalepthyphantes pseudocollinus Saaristo, 1997, Phoroncidia paradoxa (Lucas, 1846), P. pilula (Karsch, 1879) and Trochosa cachetiensis Mcheidze, 1997. An updated checklist of the spiders in the Lagodekhi Reserve is provided.

Clubiona caucasica Mikhailov & Otto, 2017 has been described from the Caucasus in Mikhailov et al. (2017). Apparently all former records of Clubiona caerulescens from the Caucasus actually belong to this new species and C. caerulescens does not occur in the Caucasus Ecoregion.

After five years the translation of Tamara Mcheidze’s book Georgian Spiders (1997) is finally finished (download Georgian original as PDF); it contains taxonomic, faunistic and ecological information on the 362 spider species recorded by T. Mcheidze in Georgia between the 1920s and 1992. The English edition resembles the original text, with a preface and taxonomic comments by me. You can download the e-book from the vifabio repository (use download link in the right column) or the direct link. It is an open access publication with a CC-BY-SA license. I also added supplementary information (pp. 401-425) on locations, a location map and an index to make the mentioned spider records more accessible. Enjoy reading!
