  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 genus and three new species of Hahniidae (Araneae) from China

Abstract

A new genus of comb-tailed spider (Hahniidae), Sinahahnia gen. nov., is described based on three new species from the high-altitude areas of China: Sinahahnia eyu sp. nov. (♂♀, Chongqing and Hubei), S. fanjingshan sp. nov. (♂♀, Guizhou), and S. yintiaoling sp. nov. (♀, Chongqing). Digital images, illustrations, and a distribution map are provided.
