Description

Females have a total length of 5.7–9.9 mm, while males are smaller at 2.8–3.6 mm. The female carapace and chelicerae are yellow-grey, with the sternum yellow and bearing irregular white patches along the middle and four pairs of sternal slit sensilla. [3]

The abdomen is pentagonal and dorsoventrally flattened, with five pairs of dorsomedian apodemes. The dorsum has a grey, brown and white pattern, while the venter has a broad white median stripe extending from the epigastric furrow to the spinnerets, with a broken white pattern around the spinnerets. The legs are whitish-yellow with dark brown spine-sockets and spines, and brown tarsi.

Males have a light brown sternum and both eye rows are recurved. The abdomen is oval with three pairs of dorsal apodemes and a dark brown scutum with a white frontal band. The venter is brown to dark grey, with three pairs of white dots around the spinnerets. [3]
