Contents: 25 species, of which 9 (36.0%) are endemic.
Endemism: 0% 100%
Other common names:
Pelias: Shield-headed Vipers
Remarks: Previously included the species now assigned to the genera Daboia, Macrovipera, Montatheris, Montivipera, and Proatheris. Dubois & Bour (2010) corrected the authorship of Vipera to Garsault (1764). It had previously been attributed to Laurenti (1968). Some authors regard Pelias as a separate genus (e.g., Tuniyev, Avci, Tuniyev, Agasian & Agasian 2012; Wallach, Williams & Boundy 2014). Two nominal species (V. magnifica Tuniyev & Ostrovskikh 2001 and V. pontica Billing, Nilson & Sattler 1990) have been shown to represent hybrids.
Distribution: NW. Africa, Europe, C. and E. Asia.

Remarks: Some authors regard transcaucasiana as a separate species (e.g., Obst 1983; Baran & Atatür 1998; Nilson, Tuniyev, Andrén & Orlov 1999; Ananjeva, Orlov, Khalikov, Darevsky, Ryabov & Barabanov 2006; Lymberakis & Poulakakis 2010; Tuniyev, Nilson, Kasaka, Avci, Agasyan, Orlov & Tuniyev 2017). Thanou, Jablonski & Kornilios (2023) presented evidence that ammodytes and meridionalis might deserve status as separate species.
Records from Syria are erroneous (possibly based on confusion with the Greek island Syra) or at least doubtful (Martens 1997; Venchi & Sindaco 2007). David & Ineich (1999) and Venchi & Sindaco (2007) regarded records from Armenia as doubtful, however, Ursenbacher, Schweiger, Tomovic, Crnobrnja-Isailovic, Fumagalli & Mayer (2008) included material (of transcaucasiana) from the country. Records from Hungary (e.g., Welch 1983) are considered erroneous (Dely 1978; David & Ineich 1999), although reported by several authors (e.g., Steward 1971; Harding & Welch 1980; McDiarmid, Campbell & Touré 1999; Anonymous 2005c). Also records from Slovakia (e.g., Arnold & Burton 1978; Saint Girons 1978; Harding & Welch 1980; Bruno 1985; McDiarmid, Campbell & Touré 1999) are considered erroneous (David & Ineich 1999).
Distribution: Albania, Austria, Bosnia-Herzegovina, Bulgaria, Croatia, Georgia, Greece (incl. Aegean Islands [incl. Cyclades Islands], Sporades Islands), Italy, Montenegro, North Macedonia, Romania, Serbia, Slovenia, Turkey (incl. European Turkey).

zinnikeri: Gascony Asp Viper, Pyrenean Asp Viper
Remarks: Taxonomic status of balcanica uncertain. It has been regarded as a synonym of ammodytes (e.g., Joger in David & Ineich 1999) or as a valid subspecies of aspis (Stojanov, Tzankov & Naumov 2011). In any case, the status of records from the Balkans (Bosnia-Herzegovina, Bulgaria, Serbia) have often been assumed to be based on misidentifications or hybrids of other species (e.g., Arnold & Ovenden 2002). Although vouchers do exist for these records (Stojanov, Tzankov & Naumov 2011), these countries have not been included in the distribution herein, pending confirmation of extant populations of aspis in the Balkans. Zuffi (2002) proposed species rank to atra, hugyi, and zinnikeri, but this has been a matter of debate (e.g., Filippi 2003). The taxon atra has recently been synonymized with aspis (Conelli, Ursenbacher, Golay, Monney, Zuffi, Thiery, Durand & Fumagalli 2004; Golay, Conelli, Durand, Monney & Thiery 2004; Golay, Monney, Conelli, Durand, Thiery, Zuffi & Ursenbacher 2008).
Extinct in: Bulgaria.
Introduced to: Italy (Montecristo).
Distribution: Andorra, France, Germany, Italy (incl. Elba, Sicily), Monaco, San Marino, Slovenia, Spain, Switzerland.

Other common names:
barani: North Anatolian Viper, (Baran's Adder)
bosniensis: Bosnian Viper, Balkan Cross Adder
sachalinensis: Sakhalin Viper
walser: Northwest Italian Viper, Piedmont Viper
Remarks: Some authors regard nikolskii as a subspecies of berus. Other authors have regarded sachalinensis as a separate species (e.g., Mertens 1934; Joger, Lenk, Baran, Böhme, Ziegler, Heidrich & Wink 1995; Adnagulov & Oleinikov 2006; Ananjeva, Orlov, Khalikov, Darevsky, Ryabov & Barabanov 2006; Wallach, Williams & Boundy 2014; Dunayev & Orlova 2023), whereas others have retained it as a subspecies of berus (e.g. Joger in David & Ineich 1999; Kalyabina-Hauf, Schweiger, Joger, Mayer, Orlov & Wink 2004; Nilson, Andrén & Völki 2005; David & Vogel 2010). It has been suggested that bosniensis might represent a separate species (e.g., Joger in David & Ineich 1999).
Presence in Shaanxi province, China, as reported by two publications in Chinese (Song 2002; Tian, Chen, Bao & Liu 2007) probably needs verification, since this is far from the nearest other known localities. Shaanxi has therefore not been plotted in the distribution map of berus, but the species has nevertheless been included in the checklist for the province.
Distribution: Albania, Austria, Belarus, Belgium, Bosnia-Herzegovina, Bulgaria, China (Jilin, Shaanxi, Xinjiang), Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Kazakhstan, Latvia, Liechtenstein, Lithuania, Moldova, Mongolia, Montenegro, Netherlands, North Korea, North Macedonia, Norway, Poland, Romania, Russia (incl. Sakhalin Island), Serbia, Slovakia, Slovenia, Sweden, Switzerland, Turkey (incl. European Turkey), Ukraine, United Kingdom (England, Scotland, Wales).

Vipera darevskii

South Caucasian Viper, (Darevsky's Viper, Darevsky's Meadow Viper)

Darevskys Kreuzotter

Sydkaukasisk Hugorm

1986 Vipera darevskii Orlov & Tuniyev
Pelias darevskii Tuniyev, Avci, Tuniyev, Agasian & Agasian 2012
2018 Pelias darevskii kumlutasi Tuniyev, Avci, Ilgaz, Olgun, Petrova, Bodrov, Geniez & Teynié
2018 Pelias darevskii uzumorum Tuniyev, Avci, Ilgaz, Olgun, Petrova, Bodrov, Geniez & Teynié

Remarks: Previously included the Turkish population now assigned to olguni (Tuniyev, Avci, Tuniyev, Agasian & Agasian 2012). The description of olguni removed darevskii from the Turkish snake fauna, however, two new subspecies of darevskii (kumlutasi, uzumorum) were subsequently described from Turkey (Tuniyev, Avci, Ilgaz, Olgun, Petrova, Bodrov, Geniez & Teynié 2018). Although claimed earlier to occur in Georgia (e.g., Golay, Smith, Broadley, Dixon, McCarthy, Rage, Schätti & Toriba 1993; McDiarmid, Campbell & Touré 1999), presence in the country has been considered doubtful (e.g., Joger in David & Ineich 1999), however, the species has recently been confirmed for the country (Tuniyev, Iremashvili & Tuniyev 2014).
Distribution: Armenia, Georgia, Turkey.


Vipera dinniki

West Caucasian Viper, Caucasus Subalpine Viper, (Dinnik's Viper)

Westliche Kaukasusotter, Westkaukasische Kreuzotter, (Dinniks Kaukasusotter)

Vestkaukasisk Hugorm

1913 Vipera berus dinniki Nikolsky
Coluber berus dinniki Nikolsky 1916
Vipera dinniki Vedmederja, Orlov & Tuniyev 1986
Pelias dinniki Tuniyev 2008
1916 Vipera tigrina Zarevsky (Golay & al. 1993)
Mesocoronis tigrina Reuss 1929

Remarks: Taxonomic status uncertain. Previously regarded as a synonym of kaznakovi (e.g., Mertens & Wermuth 1960). Suggested to be conspecific with kaznakovi, due to low genetic divergence (<1%) between the two taxa (Freitas & al. 2020).
Distribution: Azerbaijan, Georgia, Russia.

Persische Bergsteppenotter, Iranische Bergsteppenotter

Persisk Steppehugorm

1955 Vipera ursinii ebneri Knoepffler & Sochurek
Vipera ebneri Nilson, Tuniyev, Andrén, Orlov, Joger & Herrmann 1999
Vipera renardi ebneri Joger & Dely 2005
Pelias ebneri Wallach, Williams & Boundy 2014

Remarks: Taxonomic status uncertain. Regarded as a synonym of eriwanensis by some authors (e.g., David & Ineich 1999; Arakelyan, Danielyan, Corti, Sindaco & Leviton 2011), or of renardi (e.g., Sindaco, Venchi & Grieco 2013), but as a valid species by others (e.g., Nilson & Andrén 2001; Mallow, Ludwig & Nilson 2003; David & Vogel 2010). Suggested to be conspecific with eriwanensis, due to low genetic divergence (1%) between the two taxa (Freitas & al. 2020). Not listed for Iran by Kamali (2020).
Distribution: Azerbaijan, Iran.


Vipera eriwanensis

Vipera graeca

Greek Meadow Viper

Griechische Wiesenotter

Græsk Enghugorm

Kaukasisk Rød Hugorm

1909 Vipera kaznakovi Nikolsky
Coluber kaznakowi Nikolsky 1916
Pelias kaznakovi Reuss 1927
Vipera ursinii kaznakovi Schwarz 1936

Remarks: Previously included populations now assigned to orlovi (Venchi & Sindaco 2007). Two nominal species (V. magnifica Tuniyev & Ostrovskikh 2001 and V. pontica Billing, Nilson & Sattler 1990) have been shown to represent hybrids.
Distribution: Georgia, Russia, Turkey.


Vipera latastei

Snub-nosed Viper, (Lataste's Viper, Iberian Viper)

Stülpnasenotter

Iberisk Snudehugorm, (Latastes Hugorm)

1878 Vipera latastei Bosca
Latastea latastei Reuss 1929
1977 Vipera latastei gaditana Saint Girons
2021 Vipera latastei arundana Martínez-Freiría, Freitas, Velo-Antón, Lucchini, Fahd, Larbes, Pleguezuelos, Santos & Brito

Other common names:
gaditana: Southern Snub-nosed Viper
latastei: Northern Snub-nosed Viper
Remarks: Previously included monticola. Bosca used two different spellings, latastei and latasti, in the original description. David & Ineich (1999), acting as first revisors, selected the former spelling. Although Montori & Llorente (2005) suggested this action to be invalid, based on the assumption that latastei was a lapsus calami, this is not the case, since Bosca himself used the spelling latastei in subsequent publications (Speybroeck & Crochet 2007). Presence in Tunisia was questioned by Venchi & Sindaco (2007), but David & Vogel (2010) included a photo of a Tunisian specimen. Rouag, Ziane & Sousa (2024) listed monticola, but not latastei, to occur in Algeria.
Distribution: Algeria, Gibraltar, Morocco, Portugal, Spain, Tunisia.

Vipera lotievi

Caucasian Meadow Viper, (Lotiev's Meadow Viper, Lotiev's Viper)

Vipera renardi lotievi Joger & Dely 2005
Pelias lotievi Tuniyev, Avci, Tuniyev, Agasian & Agasian 2012

Remarks: Taxonomic status uncertain. Sometimes regarded as a subspecies of renardi (e.g., Joger & Dely 2005; Gvozdik, Jandzik, Cordos, Rehak & Kotlik 2012; Sindaco, Venchi & Grieco 2013). Validity as a separate species supported by Nilson & Andrén (2001). Suggested to be conspecific with renardi, due to low genetic divergence (1-2%) between the two taxa (Freitas & al. 2020).
Distribution: Azerbaijan, Georgia, Russia.


Vipera monticola

Atlas Dwarf Viper, (Atlas Mountain Viper)

Atlas-Zwergotter

Atlas-dværghugorm

1953 Vipera latastei montana Saint Girons [not Vipera montana Smith 1826; not Vipera berus var. montana Mehely 1894]
1954 Vipera latastei monticola Saint Girons [substitute name for Vipera latastei montana Saint Girons 1953]
Vipera monticola Beerli, Billing & Schätti 1986

2021 Vipera monticola saintgironsi Martínez-Freiría, Freitas, Velo-Antón, Lucchini, Fahd, Larbes, Pleguezuelos, Santos & Brito

Remarks: Martínez-del-Mármol, Harris, Geniez, Pous & Salvi (2019) regarded monticola as a subspecies of latastei, but indicated the taxonomic uncertainty of the taxon. Rouag, Ziane & Sousa (2024) listed monticola, but not latastei, to occur in Algeria. Further studies are needed on the relationship between monticola and the North African clade of latastei (Freitas & al. 2020).
Distribution: Morocco.


Vipera nikolskii

Russian Black Viper, (Forest-steppe Viper, Nikolsky's Viper, Black Viper)

1986 Vipera nikolskii Vedmederya & Grubant
Vipera berus nikolskii Joger in David & Ineich 1999
Pelias nikolskii Wallach, Williams & Boundy 2014

Remarks: Status uncertain. Regarded as a subspecies of berus by some authors (e.g., Joger in David & Ineich 1999; David & Vogel 2010; Speybroeck, Beukema & Crochet 2010; Zinenko, Turcanu & Strugariu 2010; Sos & Hegyeli 2011; Sindaco, Venchi & Grieco 2013; Mizsei, Jablonski, Roussos, Dimaki, Ioannides, Nilson & Nagy 2017), but as a valid species by others (e.g., Mallow, Ludwig & Nilson 2003; Smedt 2006; Wallach, Williams & Boundy 2014). In their checklist for Romania, Cogalniceanu, Rozylowicz, Székely, Samoila, Stanescu, Tudor, Székely & Iosif (2013) did not examine nikolskii separately from berus, and therefore did not list nikolskii for the country, although reported by other authors.
Distribution: Moldova, Romania, Russia, Ukraine.

Vipera darevskii olguni Tuniyev, Avci, Ilgaz, Olgun, Petrova, Bodrov, Geniez & Teynié 2018

Remarks: Taxonomic status uncertain. Previously regarded as a Turkish population of darevskii (e.g., Avci, Ilgaz, Baskaya, Baran & Kumlutas 2010; David & Vogel 2010). Suggested to be conspecific with darevskii, due to low genetic divergence (<1%) between the two taxa (Freitas & al. 2020).
Distribution: Turkey.
