Sitticus zimmermanni  (Bertkau, 1890)
≤ 1900   1901-1979   1980-2005   2006 ≤
Description: Carapace brown to blackish. Anterior medians distinctly nearer to each other than to laterals, medians separated from laterals by more than one diameter, laterals about twice the diameter of medians (Locket & Millidge 1953). Sternum blackish. Legs yellow-brown sometimes darker at joints. TM 1 ca. 0.18-0.22 (Roberts 1987). Abdomen yellow-brown to dark olive green. Usually dark transverse markings are present dorsally but they may be difficult to discern in specimens with dark background colours. Transverse marking often indistinct or broken in anterior half. Bars are usually distinct i posterior half, being straighter and thinner than anterior bars. Shining white patches are sometimes distributed across the dorsal surface of the abdomen, at other times mostly at sides if not absent completely. Some specimens lack both bars and white patches. Epigyne with relatively narrow scape posteriorly, male palp with a small outward directed tooth fairly high up on the paracymbium. Size: Female 2.2-3.1 mm; male 2.1-2.7 mm.

Genus: Sitticus Simon, 1901. Characters of genus: Plumb spiders, usually in darkbrown or greyish-black colours. They are characterized by having one or two pairs of white spots on the abdomen made of patches of white hairs. In some species, such as S. caricis, spots are indistinct. Legs IV clearly longer than leg III, with tibia IV about twicw as long as tibia III.

Family: Salticidae 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.
