Two subspecies are currently recognized, including the nominate race described here.ITIS|ID=635001|taxon="Vipera seoanei"|year=2006|date=19 August]

Description

Adults may grow to a length of 75 cm, but usually less.

This is a highly polymorphic species for which four main color-pattern types have been described:

A: well-developed, brown zigzig pattern down the back, very much like "V. berus", set against a beige or light-gray ground color.

B: roughly twin-striped pattern, with the ground color expressed as two narrow, straight, dorsolateral longitudinal lines along the body. Resembles "V. kaznakovi" to some degree.

C: uniform brownish morph with no pattern.

D: fragmented zigzag pattern (see "V. s. cantabrica").

Geographic range

Extreme southwestern France and the northern regions of Spain and Portugal. The type locality is given as "In montibus Gallaecorum et Cantabrorum ... d'Espagne" (the mountains of Galicia and Cantabrici, Spain). Mertens and Müller (1928) suggested a restricting the type locality to "Cabañas, Prov. Caruña, Spanien" (according to Golay et al. (1993), this is Cabañas, near Ferrol, A Caruña province, northwestern Spain).

Conservation status

This species is classified as Least Concern (LC) according to the IUCN Red List of Threatened Species (v3.1, 2001).Redlist species|no=61594|genus=Vipera|species=seoanei|date=2 September|year=2007] It was given this status due to its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. Year assessed: 2005. Redlist CC2001|date=2 September|year=2007]

It is, however, listed as a protected species (Appendix III) under the Berne Convention.
