  First insights into the role of evolutionary history in shaping venom composition of Vipera ammodytes Abstract Understanding intraspecific venom variation requires distinguishing the contributions of neutral population history from natural selection. This study aims to determine whether venom variation in the Vipera ammodytes species complex is structured across eight phylogenetic lineages. Despite a complex evolutionary history, venom composition did not differ among phylogenetic units within the analytical framework used, suggesting that shared ancestry alone does not explain venom variation. Whether local adaptation to environmental conditions explains the observed variation remains an open question for future studies.

A new species of Oecobius Lucas, 1846 from the Thar Desert, India (Araneae: Oecobiidae)

Abstract and figures

We describe a new species of Oecobius Lucas, 1846 from the Thar Desert ecoregion in India, based on both sexes: Oecobius thar sp. nov.. We also provide photographs of the new species in vivo and the general habitat of its type locality.
