Chumma
Chumma is a genus of African tangled nest spiders first described by Rudy Jocqué in 2001. They are small, three-clawed spiders with a strong dorsal scutum. They have no fovea, and the posterior and median spinnerets are reduced. The males of C. gastroperforata have two pairs of abdominal pockets that play a role in mating. This genus was initially placed in the family Chummidae, but the World Spider Catalog places it in Amaurobiidae. Species
