Trabea is an African genus of wolf spiders, with two species found in Europe.[1] It was first described by Eugène Simon in 1876.[2]

Description

Trabea are small to large spiders ranging from 3.1 to 7.8 mm in length. The sexes are alike with slight colour dimorphism in some species.[3]

The carapace is normally high with a markedly square-fronted appearance due to enlargement of the second row of eyes. Two longitudinal brown bands extend from behind the posterior eyes, though a few species lack distinct markings. The anterior row of eyes is strongly procurved with eyes either equidistant or with the lateral eyes further from the median eyes than the distance between the median eyes themselves. The second row eyes are much enlarged relative to the width of the anterior row, and the width of the posterior row is greater than the second row. The region of all eyes is blackened.[3]

Life style

Very little has been reported on the biology of Trabea species. Russell-Smith (1982) observed the South African species T. nigriceps running actively in open grassland on a dry hillside at Grahamstown.[3]

The raised carapace and black pedipalps give this species a strong superficial resemblance to some southern African species of Pardosa such as P. crassipalpis. By contrast, T. ornatipalpis and T. rubriceps have only been found in shady places in tussocky plants and under stones.[3]

Trabea heteroculata from East Africa and T. ornatipalpis appear to be restricted to montane areas where they have been found between 2000 and 3000 m.[3]

Species

As of October 2025, this genus includes sixteen species:[1]
