South African National Survey of Arachnida Photo Identification Guide: The Migidae of South Africa

The family Migidae is trapdoor spiders that live in burrows made in the soil or sac-like
nests made in trees that are closed with hinged trapdoors. They are represented by two
genera (Moggridgea O. Pickard-Cambridge, 1875 and Poecilomigas Simon, 1903) from
South Africa represented by 22 species . Both genera have been revised in 1987. Only
eight species are known from both sexes and in the majority (13) only the females are
known. Twenty of the species are South African endemics with only two Moggridgea pymi
Hewitt, 1914 and Poecilomigas abrahami (O.P.-Cambridge, 1889) having a wider southern
African distributuion. Six species are listed as Least Concern while 11 are still Data Deficient
Two species Moggridgea loistata Griswold, 1987 and Moggridgea quercina Simon,
1903 are Endangered under criterion B while Moggridgea terricola Simon, 1903 is Vulnerable
under criterion B.
