Trogulidae
The Trogulidae are a family of harvestmen with about 45 known species.
Members of this species have short legs and live in soil. They have dirt attached to their bodies, to escape predators. Their body length ranges from 2 to 22 mm. The body is in most genera somewhat flattened and leathery. Adults have a small hood, which hides their short chelicerae and pedipalps.
