Premnobius cavipennis
Eichhoff, 1878
Premnobius cavipennis is a bark beetle in the weevil Curculionidae, first described by Eichhoff in 1878. The species has a notably broad distribution spanning North America, South America, the Caribbean, Africa, and Middle America. As a member of the bark beetle guild, it is associated with woody plants, though specific ecological details remain poorly documented. The Premnobius contains relatively few described species, and P. cavipennis appears to be the most widely distributed member.

Taxonomic Note
The was described by Wilhelm Eichhoff in 1878. Catalogue of Life lists the name as 'provisionally accepted,' suggesting some taxonomic uncertainty or need for further verification. The broad geographic distribution (Neotropics, Nearctic, and Afrotropics) is unusual for a bark beetle and may warrant investigation for potential cryptic species or misidentifications.
Data Limitations
Despite the wide geographic range indicated in distribution databases, iNaturalist shows only one observation, and published biological information appears scarce. The epithet 'cavipennis' (Latin: cavus = hollow, penna = wing) presumably refers to a wing characteristic, but this has not been verified from original description.
