“…Species were identifi ed according to the literature (Bannikov et al, 1977;Kuzmin, 2012) published morphological keys and remarkable features, and using resources available online (https://www.lacerta.de/AS/Home.php). Additionally, for identifi cation of rock lizards from Darevskia complex literature resources highlighting key distinguishing features of folidosis and general morphology were used (Eiselt, Darevsky, 1991;Doronin et al, 2013;Doronin, 2017). Identifi cation of morphological anomalies was made following the work of V. Vershinin (Vershinin, 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.

Anatomical-morphological features of the postcranial skeleton of nine taxa of the rock lizards of the genus Darevskia Arribas, 1999 belonging to the Darevskia (caucasica) and Darevskia (saxicola) complexes were studied for the first time on representative samples. Specimens with the rib formula 3+1 were found in both complexes (previously, only two variants were known for the genus Darevskia 3+2 and 3+3). Differences between supraspecific groups and their members were described with the use of type specimens or topotypes of each taxon. The studied complexes are differentiated by the range of variability of presacral vertebrae (in the D. (caucasica) their minimum number is 26, in the D. (saxicola) – 27), the number of the posterior presacral vertebrae with ribs (the average value of this trait in the D. (caucasica) is less than 6, in D. (saxicola) – more than 6). B-type of the tail vertebrae in 5 times more common in the D. (saxicola) than in the D. (caucasica). In turn, the latter group is characterized by a larger share of individuals with ossified ribs at the third cervical vertebra and a greater variability of the sternal-xiphisternal costal (rib) formula. Skeletal morphology of D. alpina indicates its greater similarity with representatives of the D. (caucasica) complex. A certain originality of D. c. vedenica was recorded. The study of D. saxicola specimens from the zone of sympatry with D. c. caucasica (Chegem Gorge) did not reveal their similarity with the latter, except for the presence of two variants of the sternal-xiphisternal formula. Cryptic forms within D. lindholmi differ at least in two traits: the minimum number of posterior presacral vertebrae with short ribs and the presence of individuals with caudal vertebrae of B-type.

A total of 230 cleared and alizarin stained and 136 radiographed specimens of Darevskia belonging to 47 nominal taxa (species, subspecies or singular clades) including the seven parthenogenetic ones and a triploid hybrid were studied. Sixteen osteological characters in all the tried species were analyzed. These characters by corporal regions were: skull characters: 1.—number of premaxillary teeth; 2.—number of maxillary teeth; 3.—number of dentary teeth; 4.—teeth morphology; 5.—presence of anterolateral process in the postfrontal bone; 6.—presence of anteromedial process in the postorbital bone; 7.—comparative lengths of the postorbital and postfrontal bones; 8.—overlap degree between the postorbital and the squamosal bones. Postcranial characters: 9.—existence of visible (ossified) ribs associated with the third presacral vertebrae; 10.—sternal/xiphisternal costal formula and presence of inscriptional ribs; 11.—number of presacral vertebrae; 12.—number of posterior dorsal vertebrae (short presacral ribs); 13.—presence and form of the sternal fontanelle; 14.—form of the clavicles (emarginated or marginated); 15.—interclavicle form; 16.—morphology of first autotomic vertebrae of the tail. Our goals were to characterize osteologically the different species of Darevskia, to contrast their relationships traced from osteological traits with the available genetic-derived phylogenies of the group, to compare the osteological characteristics of the parthenogenetic species with their bisexual parental species, and to comment on their parentage and character polarity. Finally, we aimed to search for osteological characteristics of the different groups within Darevskia, diagnosing them for the first time. The results, commented on by characters, are available in the main text, and taxa characteristics are easily consultable and condensed in Table 1. Osteological characteristics of Darevskia, together with available phylogenetic trees, have permitted us to define some new groups within Darevskia (raddei, chlorogaster, defilippi, and parvula new groups) (Appendix 3), which are reciprocally monophyletic and have diagnostic characteristics. All of them are diagnosed and named as subgenera to be used if necessary, instead of the partial, old and not always comprehensive groups.
