Description

See also: Glossary of spider terms

The genus Leptodrassus is characterized by small, pale-colored gnaphosids measuring 2-6 mm in body length. Spiders in this genus have markedly enlarged anterior median eyes borne on a common, black patch, with eyes densely grouped around the anterior median eyes. The anterior lateral eyes touch both the anterior median eyes and posterior lateral eyes.^[3]

The chelicerae have two promarginal and 0-2 retromarginal teeth. The labium is wider than long, and the fovea is indistinct or absent. Males lack a dorsal scutum on the opisthosoma.^[3]
