Genyocerus albipennis, is a species of weevil endemic to Sri Lanka.^[1]^[2]^[3]

Description[]

In 1958, Victor Motschulsky formed the genus Genyocerus by citing G. albipennis as the type species.^[4] It is similar to the genus , but can be identified due to widely separated procoxae and the concave male fifth abdominal ventrite. This fifth abdominal ventrite is specialized for use as a shovel to remove frass from the gallery system. There is a considerable sexual dimorphism. Average body length is about 2.5 to 2.9 mm. Concavity of fifth ventrite without a longitudinal elevation. Lower half of frons lacks a median or lateral carinae. Pronotum with one pore on each side. Inner three teeth on elytral apex truncate. Elytral striae are not impressed on disc, but more finely punctured.^[1]

The beetle is only identified from Dipterocarpus zeylanicus.^[1]
