Bemmeridae Damarchus

Damarchus workmani Thorell, 1891

Workman’s Werewolf Spider

This spider was named in honour of Thomas Workman, an Irish businessman cum amateur arachnologist, who collected the first specimen from Singapore that was subsequently described by Thorell.

The female has a glossy black carapace, an oval abdomen densely clad with short velvety hairs, and bi-coloured legs with all patellae and tibiae tinted with chestnut brown. The double-toned legs I and II are often visible when it sits near the entrance of burrow ready to strike at a passing prey.

The male is seldom seen. It is slenderer than the female and is easily recognised by the powdery look on the carapace and on the femora.

Length♀ 20–23 mm; ♂ 15 mm
DistributionSingapore, Malaysia (Pahang).
HabitatForest floor, kerbside grassy areas or sheltered clay banks, or in rotten logs.
BiologyThe spider builds a simple burrow without any trapdoor, but with a collar around the entrance comprising mosses, leaf and wooden fragments bound together with silk. It may pull the entire rim inward to conceal the entrance.
