Erstnachweis der Wolfspinne Alopecosa barbipes (Araneae: Lycosidae) in Nordrhein-Westfalen
First record of Alopecosa barbipes (Araneae: Lycosidae) in North Rhine-Westphalia, Germany
In September 2005, one male specimen of the wolf spider genus Alopecosa was discovered and photographed in heathland near Haltern, North Rhine-Westphalia, Germany. It was identified as A. barbipes (Sundevall, 1833), as it showed the species- and sex-specific tibial hair-brush absent in the sibling species A. accentuata. Three years later, two other specimens of A. barbipes were collected in the same area. These findings indicate that the species is more widespread than originally thought. Some details concerning the distribution of A. accentuata and A. barbipes and the problem of synonymy are discussed.
