Female with a clearly marked broad median band which reach the posterior medial eyes. The width of the band anteriorly equals the width of the posterior medials, while it tapers sligthly at rear of carapace. Lateral bands are indistinct or absent. Abdomen is mottled in brown, white and grey colours. Legs brown, ringed with white hairs, more clearly at basal segments. The male is much darker than the female. The carapace is almost blackwith the median band very distinct and without lateral bands. Abdomen black with a band of whitish hairs dorsally. Legs with dark femora, remaining apical segments brown. Palps black. This species was previously known as
which has recently been split in to two separate species, of which
is a northernly species, replaced to the south by
Female 5-6 mm; male 4-5 mm.

Characters of genus:
is distinguished from other Lycosid genera by the height of clypeus being at least twice the diameter of a anterior lateral eye, and by the head having almost vertical sides when viewed from in front. Fairly small, slender species, usually with a light median band on the carapace. The genus contains a large number of species, many of which are both common and abundant. They are active during the day, and often very noticeable when running in the sunshine or basking in exposed places. Some species cannot be identified on the basis of the general appearance, and require microscopic examination of the genitals for proper identification.
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.
