Population:

Podarcis pityusensis Illa Dau Gran  (pityusensis x maluquerorum)

Types:

Holotype: nonexistent
Paratypes: ZBK 583 - ZBK 594

Terra Typica:

Dado Grande.

Taxonomic notes:

This population is due to a deliberate introduction of 8 male Podarcis pityusensis maluquerorum from Escull Vermell and 20 green female Podarcis pityusensis pityusensis from Ibiza, by EISENTRAUT in 1930.

  We report about a crossbreeding experiment by the German zoologist Martin Eisentraut, who, as part of some nature experiments in 1930 with the Ibiza wall lizard Podarcis pityusensis (BOSCÁ, 1883), released specimens of two different subspecies on the small rocky island of Dau Gran off the coast of Ibiza, which had previously been free of lizards. In this way, he hoped to gain insights into the heredity and causes of insular melanism. We want to shed light on the history of the lizards of Dau Gran and discuss the results published so far as well as the assumption mady by some authors that the population has perished, and the lizards found on the island today may be of different origin. With a new study on morphology and observations on Dau Gran we would like to show that the small lizard population has survived on the tiny rocky island to the present day.
