Common names

Meadow viper, Ursini's viper,, meadow adder, Orsini's viper, field viper, field adder. Although the following subspecies are currently invalid according to the taxonomy used here, their common names may still be encountered:

  • V. u. ursinii - Italian meadow viper.
  • V. u. macrops - karst viper, karst adder.
  • V. u. rakosiensis - Danubian meadow viper.
  • V. u. renardi - steppe viper, steppe adder, Renard's viper.

The type locality given is " ... monti dell' Abruzzo prossimi alla provincia d'Ascoli... " (mountains of Abruzzi, Ascoli Province, Italy).

Conservation status

This species is classified as Endangered (EN) on the IUCN Red List of Threatened Species with the following criteria: A1c+2c (v2.3, 1994). This indicates an observed, estimated, inferred or suspected population reduction of at least 80% over the last 10 years or three generations, whichever is the longer, based on a decline in area of occupancy, extent of occurrence and/or quality of habitat. For the same reason, a population reduction of at least 80% is projected or suspected to be met within the next 10 years or three generations, whichever is the longer. Year assessed: 1996.

In addition, this species is listed on CITES Appendix I, which means that it is threatened with extinction if trade is not halted, and is a strictly protected species (Appendix II) under the Berne Convention.


There is high genetic diversity within samples of V. ursinii and several species may be involved. At least six subspecies may be encountered in modern literature:

  • V. u. ursinii - Bonaparte, 1835
  • V. u. eriwanensis - Reuss, 1933
  • V. u. rakosiensis - Méhely, 1893
  • V. u. renardi - Christoph, 1861
  • V. u. moldavica - Nilson, Andrén & Joger, 1993
  • V. u. graeca - Nilson & Andrén, 1988

Golay et al. (1993) recognize the first four, while Mallow et al. (2003) recognize the last two. However, McDiarmid et al (1999), and thus ITIS, feel that more definitive data is necessary before any subspecies can be recognized.
