4 genera, 9 species

Dwarf tarantulas, also known as sheet funnel-web spiders are a type of spider from the family Mecicobothriidae. Dwarf tarantulas are one of several families of the sub-order Mygalomorphae; this larger group also includes the true tarantulas.



Dwarf tarantulas, as the name indicates, appear like other species of tarantula, but are physically much smaller. Many specimens are smaller than 1 cm in length, and the largest in the family are seldom larger than 2 cm. The spiders, like all Mygalomorphae, have downward pointing fangs; dwarf tarantulas also have long spinnerets.


There are currently only 4 recognized genera and 9 recognized species in this family. These are:
