Overview

What is Caucasian Brown Frog

The Caucasian brown frog (Rana macrocnemis) is biologically confirmed. Ishchenko (1978) and Tarkhnishvili et al. (1999, 2001) accept two parapatric subspecies in Georgia: R. m. macrocnemis and R. m. camerani; their ranges do not match Veith et al. (2003). The taxonomic status of R. m. camerani needs population-genomic work and formal rank may be revised — it remains a listed species here, with subspecies mentioned only as the paper does. Barcodes: Tabatskuri (camerani) and Bjolieti, Guria (macrocnemis). The checklist figure is Guria, Bjolieti.

Identification

How to identify Caucasian Brown Frog

A brown frog (Rana) — not the marsh frog (Pelophylax). Two subspecies or forms as in the paper.

  1. 01

    Rana macrocnemis; a confirmed species in the checklist.

  2. 02

    R. m. macrocnemis — Bjolieti, Guria; R. m. camerani — Tabatskuri.

  3. 03

    Figure: Guria, Bjolieti.

  4. 04

    Not Pelophylax ridibundus.

Biology

Habitat, diet, behavior, and conservation

Habitat and range

Barcodes — Tabatskuri (R. m. camerani) and Bjolieti, Guria (R. m. macrocnemis); figure locality — Guria, Bjolieti.

Conservation

Biologically confirmed. Formal status of camerani may be revised; it is not elevated to species here.

Questions

Frequently asked questions

Short answers to the most important questions about Caucasian Brown Frog.

Yes. Tarkhnishvili et al. 2026 list it as biologically confirmed. Barcodes are from Tabatskuri and Bjolieti (Guria).

Not here. The checklist names two parapatric subspecies; camerani still needs genomic work and rank may be revised, but the listed species remains R. macrocnemis.

This is Rana (brown frog), not Pelophylax ridibundus (marsh frog).

Site classification: Harmless. Venom: none.
