Abstract
During field survey in 2018, we recorded in Armenia the occurrences of the parthenogenetic lizard Darevskia armeniaca and its “paternal” bisexual species D. valentini. Based on our new data and records taken from publications and museums, we update the distribution maps of these species. The new records expand the geographical boundaries of sympatric habitats of these species and provide additional data for understanding the mechanisms of reticulate evolution and hybrid speciation.
Highlights
In a book on rock lizards of the Caucasus, Darevsky (1967) reviewed all available information on their taxonomy and all known record sites for 8 species and 20 subspecies
We present new data on the distribution in Armenia of 2 species, D. armeniaca (Mehely, 1909) and D. valentini (Boettger, 1892), which we collected during field studies conducted in 2018
The records of D. armeniaca indicated that this species is distributed rather widely in the Caucasus in northwestern Armenia, western Azerbaijan, and southern Georgia
Summary
In a book on rock lizards of the Caucasus, Darevsky (1967) reviewed all available information on their taxonomy and all known record sites for 8 species and 20 subspecies. The lizards previously placed in the subgenus Archae olacerta of the genus Lacerta were combined into the new genus Darevskia (Arribas 1999). This genus includes 33 species (AG Lacerta 2018). Most of them occur in the Caucasus region. 4 species are parthenogenetic (Dareskia armeniaca (Mehely, 1909), D. dahli (Darevsky, 1957), D. rostombekowi (Darevsky, 1957) and D. unisexualis (Darevsky, 1966)) and all occur in Transcaucasia
