Overview

Distribution

Range Description

This species ranges from northern Morocco to northern Algeria, and extreme northwestern Tunisia in North Africa, and it is also present on the Iberian Peninsula where it has a fragmented population in both Portugal and Spain (being absent from the north of Spain). The species has been not recorded in Tunisia during the last 55 years, despite targeted and intensive searches (Juan M Pleguezuelos pers. comm., October 2008). Populations of vipers from the Middle Atlas Mountains of Morocco formerly allocated to V. monticola are now recognized as belonging to V. latastei (Brito et al. 2006). It occurs from sea level up to almost 3,000 m asl.

Justification
Listed as Vulnerable because this species is probably in significant decline (at a rate of more than 30% over three generations [approximately 20 years]) because of widespread habitat loss and persecution through much of its range. Localized extinctions in parts of its range are possible (e.g. Tunisia, Spain).

Threats

Major Threats
This species has declined throughout much of the lowlands and even in the montane areas of Iberia. Threats identified include direct persecution when encountered, coastal urbanization, afforestation with coniferous trees, burning of suitable habitat, intensification of agricultural practices, and accidental mortality (particularly of males) on roads.

Vipera latastei

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[edit]

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

Description[edit]

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[edit]

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[edit]

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[edit]

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

Reproduction[edit]

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

Conservation status[edit]

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]
