Lesson plan
Devernodes
Devernodes is a genus of flightless weevils belonging to the family Curculionidae, subfamily Molytinae and tribe Lymantini. First described in 2018 by Vasily Vikotorivich Grebennikov, it comprises weevil species found in leaf-litter habitats in China, Malaysia and Vietnam. Initially, the genus was believed to belong to the Asian Stromboscerini tribe of the Dryophthorinae subfamily. Later Devernodes was placed in the Lymantini tribe due to its unique head constriction separating the eye-bearing rostrum from its head capsule and complete female hemisternites. These features, particularly the former, are unknown in Stromboscerini but are diagnostic features of the Lymantini tribe found in the Americas. It was later confirmed in 2022 through a DNA and morphological analysis that Devernodes belongs to the Lymantini tribe. As such, the Devernodes represent the first record of Lymantini weevils found outside the Americas.
