“…Th e only exemption is in the mouth of the Devashi. In general, compared to other rivers of Svanetia (Afanasyev et al, 2022) abundance was at the same level, however, the biomass of invertebrates was slightly higher, mainly due to the large size of stonefl ies Perlididae.…”

“…Today there is a relatively small amount of literature resources presenting data on distribution of fauna of Caucasus mountain from Georgian side (Bischoff , 2003;Bakradze & Chhikvadze, 2001;Kalyabina et al, 2001;Bosch & Bischoff , 2004;Ananjeva et al, 2004;Tuniyev, 2008;Tuniyev et al, 2021). Th ere scientifi c data on water invertebrate composition in the studied area is insuffi cient as well (Afanasyev et al, 2022). Additionally some fragmental data is available for some reaches of the Kura basin and some rivers of Adjara (Godunko et al, 2015).…”

This paper contains information on the records of bottom macroinvertebrates, fish, amphibians and reptiles collected during a fi eld expedition to the valley of the river Tskhenistskali (in the vicinities of town of Lentekhi and village of Sasashi) in April 2018. According to the results of the study, three fish species (Actinopterigii) of three families (Salmonidae, Cyprinidae and Nemacheilidae) inhabits three studied rivers (Kheledula, Devashi and Tskhenistskali Rivers). Seven species of reptiles (Squamata: Anguidae — 1, Colubridae — 1, Viperidae — 1, Lacertidae — 4), and five species of amphibians (Anura: Hylidae — 1, Bufonidae — 1, Ranidae – 2; Caudata: Salamandridae — 1) were registered within the investigated area. Around Lentekhi town three species of the genus Darevskia Arribas, 1999, namely Darevskia rudis svanetica (Darevsky & Eiselt, 1980), Darevskia brauneri brauneri (Mehely, 1909) and Darevskia derjugini abchasica (Bischoff , 1982) were found to live almost sympatrically, with only river serving as a natural barrier between the species. The paper also contains descriptions of habitats characteristic of the region for the species found and the results of route surveys with D. d. abchasica and P. ridibundus being the most numerous species of herpetofauna (sensu lato) — up to 35 and 20 individuals per 100 m of route. In order to illustrate the feeding base of the registered vertebrates, the study of species composition (n = 114) of bottom macroinvertebrates, that form the main component of food source for them. The recorded invertebrates belong to 16 taxonomic groups of the higher rank (up to 98.1 % of all benthic invertebrates appeared to be insects, including Ephemeroptera — 51 %, Plecoptera — 17.4 % Сhironomidae — 14.2 %, Trichoptera — 11.5 %, Diptera — 3 %). Other groups, namely Turbellaria, Nematoda, Oligochaeta, Araneida, Acarina, Collembola, Heteroptera, Coleoptera, in total form a little less than 3 % of all recorded species. Registrations of fauna from mountain regions will help to update actual maps of natural ranges of the species within the country and tend to be a valuable addition to the data that can be potentially used in GIS-modelling of species’ distribution according to predicted climate changes.

Recent Georgia’s fish fauna includes four Capoeta species: C. capoeta (Kura River basin), C. kaput (Araxes River and its left tributaries, the Akhuryan and Mezamor rivers), C. sieboldii (East and South–East Black Sea river basins), and C. banarescuii (Chorokh River basin). Based on morphological data analysis new species of the genus Capoeta — C. svanetica sp. n. is described. It is more similar to the Capoeta damascina complex group (Anatolian–Iranian group) which also includes C. banarescui, C. baliki, and C. sieboldii spread at East and South-East Black Sea coastal rivers. The Anatolian–Iranian group, also known as small-scales species group well distinguished from Aral-Caspian species (C. capoeta and C. kaput in Georgia) by highest scales number in lateral line. C. svanetica sp. n. is distinguished from other Capoeta species of Black Sea basin rivers in Georgia and adjacent waters by combination of characters: two pairs of barbels are present (C. sieboldii and C. oguzelii have one barbels pair); no spots on the body (C. oguzelii has small black spots); lower lip has keratinised edge without fringe (C. sieboldii and C. oguzelii are characterized by fringed lips); scales small, 70–74 total lateral line scales (in C. sieboldii only 52–60 scales); 10–12 scale rows above lateral line (C. banarescui, C. baliki and C. oguzelii have more than 12 scale rows) and 7–8 scale rows below lateral line (C. baliki and C. oguzelii have more than 10 scale rows); 12–15 gill rakers on the first gill arch (C. sieboldii and C. baliki have more then 16); last unbranched fin ray soft, serrae number on it is 7–9 in adult and 0 in juvenile samples (all other Capoeta species of Black Sea basin rivers have well ossified last unbranched ray with high serrae number); anal fin base length is only 7.4–9.4 % of SL (more shorter than C. banarescui, C. baliki and also C. tinca); as well as mouth width (25.4–29.4 % of HL); eye diameter (19.0–28.7 % of HL) is biggest than same in C. banarescui, C. baliki and also C. tinca.
