Brauner's Rock Lizard
Darevskia brauneri
A candidate rock lizard in the D. saxicola complex; the Ertso population is a subspecies, not a separate species — colour is not enough.
Overview
What is Brauner's Rock Lizard
Brauner’s rock lizard (Darevskia brauneri) is a candidate species in Tarkhnishvili et al. 2026, in the Darevskia (saxicola) complex. Species status is widely accepted, but it is unclear how far stepped genetic and phenotypic clines separate it from D. saxicola or D. szczerbaki. Mitochondrial haplogroups from some Georgian populations of nominal D. brauneri are closer to North Caucasian D. saxicola than to formally conspecific populations. Distribution is restricted to the western and central Greater Caucasus. D. arribasi from near Ertso Lake is treated here as D. b. arribasi: diagnostic scalation and morphometrics fall within variation of western Caucasian brauneri and of Enguri and Tekhuri basin populations, and mtDNA divergence is on a ≈2% scale. Subspecies D. b. myusserica occurs locally in northwestern Georgia.

Identification
How to identify Brauner's Rock Lizard
Colour is not enough. Field ID among Darevskia needs scalation and range, not colour. Scalation reported for “arribasi” at Ertso falls within brauneri variation in the paper.
- 01
Colour does not separate Darevskia species.
- 02
saxicola complex; scalation clines versus D. saxicola / D. szczerbaki are unclear.
- 03
D. arribasi (Ertso) is a subspecies here: diagnostic scalation is within brauneri variation.
- 04
Checklist figures show head scalation and preanal plates (Mestia, Manshura).
Questions
Frequently asked questions
Short answers to the most important questions about Brauner's Rock Lizard.
The paper keeps the Ertso population as D. b. arribasi, not a separate species. D. saxicola is North Caucasian; some Georgian brauneri mtDNA is closer to it. Colour will not tell them apart.
Contact zones in the saxicola complex are insufficiently tested; species rank is widely accepted but gene flow is not ruled out.
Western and central Greater Caucasus. Figure: Mestia, Manshura; barcodes: Martvili and Manshura; also Ertso Lake, Enguri, Tekhuri. Abkhazia is not named in the remark; D. b. myusserica is listed from northwestern Georgia.
