Representatives of the Megaloptera order are quite widespread in the world and number 380 modern species. Among them family Corydalidae Leach 1815 includes two subfamilies (Corydalinae Leach 1815 and Chauliodinae Davis, 1903) and 25 genera. They consist of more than 200 species. The fauna of Vietnam currently includes 29 species of Corydalidae.

The study of the insect fauna of Central Vietnam during the joint Belarusian-Vietnamese expedition made it possible to make additional finds of Corydalidae on the territory of the Pu Hoat Nature Reserve and Pu Mat National Park (Nghe An Province). The material for this article was the authors' collection during in April and May, 2025. All collected species belong to the subfamily Corydalinae — dobsonflies. The subfamiliy is distributed in the temperate, subtropical and tropical areas of North and South America, Africa, Australia, New Zealand, East and Southeast Asia.

The research resulted in new finds of three species of Corydalidae from protected natural areas in Central Vietnam. The coloration of the head and pronotum of these species is illustrated. Three species of dobsonflies are listed from Pu Mat National Park and two species are recorded from Pu Hoat Nature Reserve. Neoneuromus orientalis Liu & Yang, 2004 and Nevromus exterior Navás, 1927  are indicated for the first time for Nghe An Province
