Megalopsidiinae

Leng, 1920

The Megalopsidiinae are a monogeneric subfamily of the Staphylinidae, which includes only the genus Megalopinus . [1] They have large eyes, antennae with distinct di- or trisegmented clubs. The tarsal formula is 5-5-5. They have unique elongated processes at the anterior margin of the labrum. They are found in decaying trees and fungus-infested logs. [2] Four species are found in North America: Megalopinus caelatus (Gravenhorst, 1802), Megalopinus punctatus (Erichson, 1840), Megalopinus rufipes (LeConte, 1863) and Megalopinus lingafelteri Mainda, 2023.

So far, 333 species are known from the entire New World. [3] From the Orientalis 74 (+ one fossil, Megalopinus extinctus Yamamoto & Solodovnikov, 2016, described from Burmese amber [4] ) species are known. [5]

The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is the largest family in the beetle order, and one of the largest families of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus Leehermania proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems.

Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
