Type species: Perigona pallida Laporte, 1835 by monotypy. Etymology. Uncertain, either from the Greek peri (around, near, very) and gone (offspring) or from Perigone, daughter of the brigand Sinis. According to Desmarest (1851: 104), the name derives from the Greek peri and gonia (angle) [feminine]. Diversity. Excluding the subcosmopolitan Perigona nigriceps , about 105 species (Lorenz 2005: 438-439) in the temperate, subtropical, and tropical areas of the Nearctic (one species), Neotropical (twelve species), Australian (about 17 species), Oriental (about 30 species), eastern Palaearctic (five species), and Afrotropical (about 40 species) Regions. These species are arrayed in 12 subgenera: Cryptoperigona Perrault (one Neotropical species), Euripogena Basilewsky (four Afrotropical species), Euryperigona Jeannel (three species in the Philippines, Indonesia, and New Guinea), Hirtoperigona Perrault9 (two Oriental species), Neoperigona Perrault (three Neotropical species), Perigona s.str.
