Protohermes
Sign in to saveProtohermes is a genus of dobsonflies in the family Corydalidae. Protohermes is the most speciose and widely distributed genus within Megaloptera, but up to 85% of species are restricted to small endemic areas in Asia. This endemism may be a result of an association with high elevation and high slope streams in Northern Vietnam and China.

Protohermes is a genus of dobsonflies in the family Corydalidae. Protohermes is the most speciose and widely distributed genus within Megaloptera, but up to 85% of species are restricted to small endemic areas in Asia. This endemism may be a result of an association with high elevation and high slope streams in Northern Vietnam and China.
== Description == Adult Protohermes generally have yellow coloration with white spots on the wings. The male genitalia are diverse across the genus and can be useful only for species-level identification, especially the shape and size of the tenth tergum and the subgenital plate at the ninth sternum. Nuptial gifts in Protohermes may as large as 20% of the total body mass of the male and can require up to 2 days to recover before mating again.
