Just out | Discovery of the oxyporine rove beetle in the Mesozoic amber and its evolutionary implications for mycophagy (Coleoptera: Staphylinidae) @ Cretaceous Research

Just out @ Cretaceous Research


Oxyporinae is a distinct staphylinid subfamily characterized by a large body, remarkably long and projecting anteriorly mandibles, and large, crescent-shaped terminal labial palpomeres. Previously, only three compression fossils from the Lower Cretaceous Yixian Formation in China were known for the subfamily from the Mesozoic era. This study describes a remarkable new species, Oxyporus cretaceous sp. nov., based on a single specimen in Upper Cretaceous Burmese amber. This finding is the earliest record of Oxyporinae preserved as amber inclusion. The beautifully preserved mouthparts suggest that mycophagous feeding habits had already been acquired by the mid-Cretaceous.
