Nemesia sp., copyright Ferran Pestaña.

Belongs within: Avicularoidea.
Contains: Anamini.

The Nemesiidae are a fairly generalised family of mygalomorph spiders characterised by a double row of teeth on the paired leg claws, at least in females. They live in silk-lined burrows of various forms, with some species closing their burrow with a lid. In most subfamilies, both males and females have biserially dentate leg claws but in males of the subfamily Bemmerinae the teeth are arranged in an S-shaped row (Jocqué & Dippenaar-Schoeman 2007).

Characters (from Jocqué & Dippenaar-Schoeman 2007): Medium-sized to very large; cephalic region low; eight eyes present in two rows; palpal claw of female with teeth on promargin; tarsi with scopulae, three tarsal claws present or rarely two, paired claws broad, biserially dentate; four spinnerets present, apical segment of posterior spinnerets digitiform.
