Common names: Lataste's viper, snub-nosed viper,[3] snub-nosed adder.[4]

Vipera latastei is a venomous viper species endemic to extreme southwestern Europe and northwestern Africa.[2] Two subspecies are currently recognized, including the nominate subspecies described here.[5]

Etymology

The specific name, latastei, is in honor of French herpetologist Fernand Lataste.[6]

Description

V. latastei grows to a maximum total length (body + tail) of about 72 cm (28.3 in), but usually less.[3] It is grey in colour, has a triangular head, a "horn" on the tip of its nose, and a zig-zag pattern on its back. [7] The tip of the tail is yellow.

Behaviour

It can be seen day or night but is usually hidden under rocks. The yellow tip of the tail is possibly used to lure prey.[8]

Geographic range

It is found in southwestern Europe (Portugal and Spain) and northwestern Africa (the Mediterranean region of Morocco, Algeria and Tunisia).

The type locality given is "Ciudad Real", emended to "Valencia, Spanien" (Valencia, Spain) by Mertens and L. Müller (1928).[2]

Habitat

This species is found in generally moist, rocky areas, in dry scrubland and woodland, hedgerows, stone walls and sometimes in coastal dunes. [9]

Reproduction

The females give birth to between two and 13 young. On average, females give birth only once every three years. [9]

Conservation status

This species was classified as Near Threatened (NT) according to the IUCN Red List of Threatened Species (v3.1, 2001), from 2008 is recognised as Vulnerable (VU).[9] Listed as such because it is probably in significant decline (but likely at a rate of less than 30% over ten years) due to widespread habitat loss and persecution throughout much of its range, thus making the species close to qualifying for Vulnerable. Further population reduction is expected, but is not likely to exceed 30% over the next 10 years, but localized extinctions in parts of its range are possible (e.g., Tunisia). Year assessed: 2005.[10]

It is also listed as a strictly protected species (Appendix II) under the Berne Convention.[11]

Subspecies

Species[5] Taxon author[5] Geographic range
V. l. gaditana Saint-Girons, 1977 Southern Spain and Portugal, Morocco, Algeria, Tunisia.[2][3]
V. l. latastei Boscá, 1878 Most of the Iberian peninsula south of the Pyrenees.[3]
