≤ 1900   1901-1979   1980-2005   2006 ≤
Description: Female carapace dark brown with a light median band that is pale brown anteriorly, then pale yellow and ends at an U-shaped dark marking posteriorly, with the bottom of the U pointing towards the abdomen. Lateral bands pale yellowish-brown, broken and irregular. Abdomen brown with dark brown, elongate cardiac mark outlined with thin blackish line. The cardiac mark is enclosed by a pale yellowish-brown median band. Sides of abdomen brown. Anteriorly on the abdomen there is another U-shaped drawing with the bottom pointing towards the carapace. Sometimes thin transverse lines connects paired white spots on the rear half of the abdomen. Legs dark brown with yellow-brown hairs and stout, dark spines. Male carapace with white median band in contrast to almost black sides, and with thin yellow-brown lateral bands. Abdomen with light median band that is lightest anteriorly, and with indistinct cardiac mark. Tibia I and inward segments very dark, on legs II only femora and inwards segments are darkened. Remaining segments brown as in the female. Size: Female 7-10 mm; male 5-8 mm.

Genus: Alopecosa Simon, 1885. (Fox-spiders). Characters of genus: Alopecosa seconds Pardosa 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.

Family: Lycosidae 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 three rows 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 sternum is oval to shield shaped (scutiform). The chelicerae are relatively strong with toothed cheliceral furrow and prominent lateral condyle (boss). The labium 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.
