Distribution and ecology

Trogulus torosus occurs mostly near the coast, usually in the entrance areas of caves. While less common, specimens have been recorded outside of caves, usually retreating into layers of rock. Cave records are common due to more thorough research and specimens retreating into more accessible areas.^[2]

Description

The body is red-brown, elongated, and flat, with inconspicuously short hairs and a prominent medial ridge. Small papillae (bumps) occur across much of the prosoma and opisthosoma. The legs are robust, with hairs only conspicuous on the metatarsus and tarsus segments.^[2]
