Introduction to the Megaloptera
The insect order Megaloptera is considered one of the most primitive of the holometabolous insect orders and comprises two families: Sialidae & Corydalidae. The Corydalidae are divided into two subfamilies: Chauliodinae and Corydalinae. Globally there are about 300 extant species. The Afrotropical region is particularly understudied, with only 11 described species restricted in distribution to South Africa (7 species) and Madagascar (4 species). The Megaloptera fauna of the rest of Africa is unknown.
