Cryptorhynchina is a subtribe of weevils within the Cryptorhynchinae, commonly known as hidden-snout weevils. The group has gained scientific attention through fossil evidence showing that at least one extinct within this lineage served as an orchid approximately 20–45 million years ago. No present-day members of this subtribe have been documented carrying orchid pollinaria, though this absence may reflect their secretive rather than lack of ecological interaction.

Fossil Pollination Evidence
The first fossil evidence of beetles dispersing orchid pollinaria involved a Cryptorhynchinae weevil in Dominican amber, establishing that -orchid pollination relationships extend back at least 20 million years. This finding suggests beetles may have played a more significant role in orchid evolution than previously recognized.
