This is the largest
species occurring in Denmark. The clear markings of the carapace and abdomen are characteristic and enable easy identification in the field. The ventral side of the prosoma (coxa, sternum, labium og maxilla) are dark brown to black while the underside of the abdomen is soothy black. Female carapace with wide light median band broadened anteriorly and covering the entire eye region. Two dark spots are present at the rear of the carapace opposite two kidney shaped blotches on the abdomen. Further back on the abdomen, there are two more spots at the first pair of the rather faint chevrons. Male is slimmer than the female and with more contrasted markings. Tibia I is not darker than other leg segment, swollen or furnished with long dark hairs as in males of other
Female 14-15 mm; male 10-12 mm.
Simon, 1885. (Fox-spiders).
Characters of genus:
in species richness within the Lycosidae. Medium-sized to large spiders with clear median band on the carapace wider than the eye group. Legs are stout with some males having swollen tibia I. Abdomen with clear cardiac mark. The species can be grouped by the colour of the ventral surface which is black in some species and light-coloured in others. The females dig a burrow where they guard their egg sack.
Sundevall, 1833 (Wolf Spiders).
Characters of family:
The lycosids belong to the group of araneomorph, ecribellate spider families having 8 eyes and 3 tarsal claws. The eyes are all dark in colour and arranged in
in a characteristic fashion. The anterior row has four small eyes set in a straight or slightly curved row, the second row has two large eyes further up on the on the vertical front, and the posterior row has two medium-sized eyes on the sides of the head which can be more or less steep sided. There are only few additional diagnostic characters of importance for the family, i.e. the lack of a retrolateral tibial apophysis on the male palp and that the female of many species carries her egg sack attached to the spinners. The carapace is longer than wide with the head region narrowed and high. It is usually densely covered with hairs and often with longitudinal median or lateral bands or both. In some genera there are characteristic bars in the median band or elongate U-, Y-shaped marks. The
is oval to shield shaped (scutiform). The chelicerae are relatively strong with toothed cheliceral furrow and prominent
is a wide as long, about half the length of endites. Legs are spinose and provided with 3 tarsal claws, usually with scopulae for adhesion. The second segments of the legs (trochanters) are notched. The abdomen is oval, always covered with dense hairs. There is no colulus in front of the spinners. The tracheal spiracle is situated just in front of the spinners. The epigyne is well sclerotized median septum which may be large and plate-like. The male palp is only rarely provided with a tibial apophysis. The tip of the male palp may have one or more claws.
Female. Characteristic sooty-black venter
