Allometrie sowie Bau und Funktion der Kopulationsorgane bei der Wolfspinne Arctosa leopardus (Araneae, Lycosidae)

Abstract

The prosoma length of adult males and females of the lycosid spider Arctosa leopardus (Sundevall, 1833) varies by about 200%. By contrast, the decisive structures of the copulatory organs show allometrically constant sizes. Male and female copulatory organs are described in detail. Their mechanical co-operation in copula is discussed.
