The species inhabits the Thicketbiome. Stasimopus kolbei constructs silk-lined burrows closed with a cork-lid door. The lid is thick and cork-shaped with a broad hinge. The peripheral surface is strongly marked and the lid edge is scarcely bevelled, except on the hinge side. The underside is flattened with pits almost obliterated.
The species was originally described by Purcell in 1903 from the type locality in Kentani. It has not been revised since its original description and remains known only from the female specimen.
