In this work, the synonymy suggested by Yao, Tavano & Li (2013) is confirmed and proposed formally. Furthermore, the material tentatively identified by Huber (2011) as P. gracillimus is determined to be a new species, matching no species known at the time of Huber (2011), nor any of the Pholcus species described after 2011. It is thus formally desc...

This study investigated changes in ground-hunting spider communities (families Ctenidae, Lycosidae and Zodariidae) in an actively restored forest, an unrestored gravel mine, and two alternative land-use typ...

Copulation is essential for transferring sperm from males to females in most animals. During copulation, males and females are often static and thus prone to predation or other threats. Its duration should therefore be reduced to minimize costs but sufficient to ensure the fertilization of eggs. Here, we investigated reproductive behavior and succe...
