Über eine bemerkenswerte Verhaltensweise von Scotophaeus scutulatus (Araneae: Gnaphosidae)

It is described, how an adult female of Scotophaeus scutulatus killed an also adult female of Tegenaria atrica in the web of the latter species. According to published and unpublished data, a web-invading behaviour is known in 4 gnaphosid species (Poecilochroa senilis, Poechilochroa pugnax, Scotophaeus blackwalli, Taieria erebus), an araneophagic behaviour is also known in 4 species (Drassodes lapidosus, Poecilochroa senilis (auspex), Scotophaeus scutulatus, Taieria erebus). the question, wether these behaviour patterns are typical for soil-dwelling gnaphosids, remains open until further observations and investigations.
