|Distribution||W Caucasus (50-1100 m elevation)|
Type locality: Papai Mountain, Krasnodarskii region, Russia
|Types||Holotype: SNP (given as SD CSNBR 528), adult male, (Scientific Department, Caucasian State Nature Biosphere Reserve, Sochi), May 12, 1997, coll. S. V. Ostrovskikh.|
|Diagnosis||Diagnosis. A medium-size viper of the Eurosibe-rian group. Head has more light coloration than body. Canthals and labials are white. Number of ventral shields and number of crown shields are the least for all representatives of "kaznakovi" complex.|
|Comment||Synonymy: this species may be synonymous with V. (P.) dinniki (Mallow et al., 2003, Smedt, 2006). The genome of V. orlovi is composed of the genomes of Vipera kaznakovi (major part) and of Vipera renardi (about 20%). V. orlovi is intermediate in ecology between its ‘parental species,’ however its habitat is not the typical habitat of neither V. kaznakovi nor V. renardi. As all three taxa are allopatric, there is no evidence of current geneflow between them, hence Joger & Zinenko 2021 proposed to maintain species status for V. orlovi.|
Conservation: one of the 30 most endangered viper species (Maritz et al. 2016).
Distribution: For a map see Sindaco et al. 2013.
|Etymology||Species is named after the Russian herpetologist — Nikolay L. Orlov, who made an im-portant contribution to the study of Caucasian vipers.|
