C. L. Koch, 1835
Rather uniformly coloured dark spider with purple metallic sheen. There is only a faint white band anteriorly on the abdomen. The palps of the female are light brown, while those of the male are dark with white squamose hairs on the forward directed surface. The same type of white hairs are present on the legs, however less pronounced in this species than in other members of the genus.
Female 4.5-5 mm; male 3.5-4.5 mm.
C. L. Koch, 1833.
Characters of genus:
These are dark, blackish spiders, usually with metallic sheen in green, violet or coppery colours. Some species are furnished with white bands or spots on the abdomen composed of white squamose hairs. The palps of the females are ligth brown in contrast to the overall dark appearance of the spider. The male palps are dark but furnished with white squamose hairs on forward directed surfaces. Some species have legs in light yellow colours while other have dark legs with white squamose hairs.
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.
