Description

Only the male has been described. Its body is about 9 mm long in total. The upper (dorsal) surface is generally light reddish brown; the lower (ventral) surface is lighter. The abdomen has a darker pattern on both surfaces. The ventral surface of the tarsus and part of the metatarsus of each leg is white. The legs are densely covered with relatively long hairs.[2]

Taxonomy

Sason hirsutum was first described by Peter J. Schwendinger in 2003.[1] The species name, hirsutum, meaning "hairy", refers to the long dense hair on the legs. The male is similar to S. andamanicum, but can be distinguished by a number of features, including the short, stout cuspules on the labium and maxillae, and the thinner, straight embolus of the palpal bulb.[2]

Distribution and habitat

The species is only known from one of the Lingga Islands off the east coast of Sumatra, Indonesia. The males were found in tropical rainforest alongside a stream, in nests on the trunks of trees.[2]

gollark: For some reason my task scheduler is consistently off by exactly an hour.
