Comment

Başoğlu and Özeti, 1973, Türkiye Amphibileri: 36–37, provided an account for the Turkish populations (as Mertensiella caucasica). Özeti and Yilmaz, 1994, Türkiye Amfibileri: 51–54, provided an account for Turkish populations (as Mertensiella caucasica). Tuniyev, 1999, Adv. Amph. Res. Former Soviet Union, 3: 48-49, discussed the status and distribution of Mertensiella caucasica djanaschvilii. Beşir and Gül, 2019, Herpetol. Notes, 12: 45–51, provided a dot map for Rize Province, northeastern Türkiye (as Mertensiella djanaschvilii). See comments under Mertensiella caucasica noting literature that included this taxon as a subspecies of that species. Kurnaz and Kutrup, 2019, Nat. Conserv. Res., 4: 109–111, provided new localities and modeled the distribution in Gümüşhane province in Türkiye (as Mertensiella caucasica). Çiçek, Yakin, Afsar, Ayaz, and Tok, 2019, Acta Biol. Turcica, 32: 37–41, provided new localities in Türkiye and a dot map for the species' range (as Mertensiella caucasica). Yaşar, Çiçek, Mulder, and Tok, 2021, North-West. J. Zool., Romania, 17(e201512): 232–275, discussed and grid-mapped the range in Türkiye (as Mertensiella caucasica). Raffaëlli, 2022, Salamanders & Newts of the World: 255, resurrected the name Mertensiella djanaschvilii on the basis of evidence presented by Tarkhnishvili, Thorpe, and Arntzen, 2000, Mol. Phylogenet. Evol., 14: 414–422, and Tarkhnishvili, Kaya, Gavashelishvili, and Serbinova, 2008, Herpetol. J., 18: 155–163.
