Georgia bottom macroinvertebrates fish herpetofauna species distribution mountain rivers Lower Svanetia rivers Tskhenistskali River basin 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.
