Short communicationFirst fossil Coloninae from Upper Cretaceous Burmese amber (Coleoptera: Staphylinoidea: Leiodidae)
چکیده انگلیسی

Fossil leiodids are sparse, and they are confined to the Cenozoic. Here we describe and illustrate the first definitive Mesozoic leiodid, Colonellus burmiticus sp. nov., based on two well-preserved adults from the Upper Cretaceous Burmese amber. The fossil is firmly placed in the extant Coloninae based on multiple synapomorphies, such as antennae with normal-sized antennomere 8 and abdominal intersegmental membranes with “brick-wall” pattern. It can be further assigned to the extant genus Colonellus (subgenus Pentacolonellus) by its five-segmented antennal club. The discovery suggests that Colonellus is an ancient group, originating no later than the mid-Cretaceous.
