Aberrante Epigynenbildungen bei der Wolfspinne Pardosa palustris (Araneae, Lycosidae)

Abstract

Two cases of aberrant epigyne shape in Pardosa palustris (Linnaeus, 1758) are described. Characteristic is the absence of the posterior lateral parts of the septum. Possible causes, such as `genital damage` during mating or the effects of parasite infestation, are discussed.
