Taxonomy
editP. najadum was first described by Karl Eichwald in 1831,[1] as Tyria najadum.[2]
Geographic range
editP. najadum is found in the Balkans, Aegean, Cyprus, the Mid-East, and as far as Turkmenistan and the Caucasus Mountains.[3]
Habitat
editP. najadum occurs in dry and xeric environments in a wide range of habitats: in desert and rocky land, in forests, woodland scrub, and agricultural land from sea level to 2,000 m (6,600 ft) altitude. It is commonly found in fields, and seen crushed on roads.[1]
Description
editP. najadum has a slim body, and is rarely over a metre (39 inches) in total length (including tail).[4]
Conservation status
editP. najadum is threatened by direct persecution, forest fires and intensive agriculture, where its range interacts with human interests. The species is listed on Annex II of the Bern Convention and Annex IV of the European Union Habitats Directive. It has varying protection in some countries including Serbia, Montenegro, Russia, and Lebanon.[1]
Reproduction
editP. najadum is an egg laying species. Females lay between 3 and 16 eggs in a clutch.[1]
Subspecies
editFour[2] subspecies are identified, including the nominotypical subspecies.
- Platyceps najadum albitemporalis (Darevsky & Orlov, 1994)
- Platyceps najadum dahlii (Fitzinger, 1826) – Balkans, Cyprus, Aegean Turkey
- Platyceps najadum kalymnensis (B. Schneider, 1979) – endemic to Kalymnos island, the Aegean
- Platyceps najadum najadum (Eichwald, 1831) – Caucasus and Asia Minor
A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Platyceps.
Etymology
editBoth the subspecific name, dahlii, and the common name, Dahl's whip snake, are in honor of Austrian entomologist Georg Dahl (1769–1831) who collected the type specimen in Dalmatia in 1824.[5]
The subspecific name, schmidtleri, is in honor of German herpetologist Josef Friedrich Schmidtler (born 1942).[6]
Indigenous names
editΣαϊτα (Greek), Saita, Стрелушка (Bulgarian), šilac (Croatian), Za'aman Z'eitani (Hebrew), Ok Yılanı (Turkish).
