The Caucasus region is among the most important Eurasian biodiversity hotspots (Zazanashvili et al. 2004, Walther et al. 2014). Its mollusc fauna is far from being well-explored and, as indicated by a number of recent studies, one could reasonably expect further taxonomical discoveries in this region. The diversity and distribution of the mollusc f...

Holospira (Bostrichocentrum) goldmani Bartsch, 1906 is an urocoptid gastropod distributed throughout northwestern Oaxaca in southern Mexico. Since its original description, posterior records have been restricted to the Mixteca Baja region of Oaxaca. The purpose of this paper is to expand on the geographical distribution of this species, georeferenc...

... By contrast, the tumultuous first half of the 20th century proved unfavourable for mollusc studies, yielding only few clausiliid-related papers (Rosen 1914;Kokochashvili 1940Kokochashvili , 1941Javelidze 1941). Thereafter a renewed interest in the region's land snails resulted in several further contributions (Likharev and Rammelmeier 1952;Likharev and Lezhava 1961;Likharev 1962;Lezhava 1962Lezhava , 1964Lezhava , 2004Nordsieck 1975Nordsieck , 1976Natsvlishvili 1967;Sysoev and Schileyko 2009;Pokryszko et al. 2011;Fehér et al 2014;Mumladze et al. 2017;Hausdorf et al. 2018;Mumlaze and Szekeres 2020;Neiber et al. 2021) that considerably increased our knowledge of the Georgian Clausiliidae fauna. As a result, the taxonomic positions and distribution areas of the species, as well as the fauna composition became quite well assessed. ...
... The occurrence data listed in the Results are based on georeferenced samples that were collected during the past two decades. For comparison, the maps showing the occurrence points also include well defined locality data that have been provided in the publications of Majoros and Németh (1997), Pokryszko et al. (2011), Fehér et al. (2014, Mumladze et al. (2017) and Neiber et al. (2021). ...
The Caucasus ecoregion is one of the most important biodiversity hotspots in western Eurasia. Georgia is situated in the middle of this area, between the ranges of the Greater and Lesser Caucasus, a position providing exceptionally balanced environmental conditions for its flora and fauna. Animal groups of low mobility, such as land snails, are important indicators of the past and present geographic and climatic events shaping these unique ecosystems. We give an overview of the land snail family Clausiliidae in Georgia that includes 30 species, among which eight are endemic to this country. Their distribution areas are reassessed in the light of novel georeferenced occurrence data resulting from recent field work. Aspects of the origin, diversity, habitat requirements and conservation status of the Georgian Clausiliidae fauna are discussed. Additionally, Mucronaria (Mucronaria) kartvelica sp. n. is described from the Racha-Lechkhumi and Kvemo Svaneti Region.
... Most of these taxa had been described by the end of the 19th century, but it took more than six decades to get the first comprehensive assessment of this fauna published by Likharev [1962]. Only in recent years was his fundamental work followed by other works that dealt with particular groups [Majoros et al., 1994;Suvorov, 2002;Kijashko, 2005;Pokryszko et al., 2011;Fehér et al., 2014;Koch et al., 2016] or gave updated overviews [Egorov 2001[Egorov , 2002Sysoev, Schileyko, 2009] of these snails. This renewed interest resulted in the discovery of new endemic species, as well as valuable taxonomic and zoogeographical contributions, in which further progress is foreseen. ...

We evaluated progress towards animal biodiversity research in Georgia, a key area in the Caucasus biodiversity hotspot. By reviewing recently (1990–2018) published articles in all areas of animal diversity research, we unmasked the trends in biodiversity inventory, ecological and biogeographical studies, and conservation issues in Georgia. We concluded that species inventory and biodiversity research in Georgia has significantly increased during the last ten years, however the rate and extent of investigation is far from satisfactory. Major gaps remain in all branches of animal diversity research in Georgia, and consequently existing knowledge is inadequate to address modern challenges related to species and ecosystem conservation. We urge local governmental authorities and international scientific societies to support development of stronger research facilities and cultivate interest in biodiversity inventory and research in Georgia as an important step towards maintaining globally important biodiversity in the Caucasus.
