Large species with flattened, elongate abdomen, thickly covered with light hairs. The ground colour is black but is usually mostly hidden by the dense hair coverage, unless the hairs have become rubbed off. The abdomen is usually whitish with a black median and some angulate, chevronlike black lines.
Female 8-10 mm; male 6-8 mm.
C. L. Koch, 1846.

Blackwall, 1841 (Jumping spiders).
Characters of family:
Small to medium-sized, shortlegged spiders easily recognizable by the characteristic eyes arranged in three rows. The anterior row of eyes is situated on a more or less vertical face, the medians being very large, the laterals somewhat smaller and set higher on the head. The second row of eyes consists of two very small, often minute or vestigial eyes set further back on the head. The two eyes of the posterior row are about the same size as the anterior laterals, and are set about halfway back on the carapace at the edges of the head. The anterior medians are highly sophisticated providing acute vision used to leap accurately while moving around as well as capturing prey and escape efforts.
