Ptiliidae

Ptiliidae (Ptenidium pusillum) is a family of very tiny beetles (including the smallest of all beetles) with a cosmopolitan distribution. They are colloquially called featherwing beetles, because the hindwings are narrow and feathery.

Pteryx is a genus of beetles that is typically found in northern bogs in the Northern Hemisphere. They belong to the family Ptiliidae which is referred to as feather-winged beetles as the hindwings are narrow and feather-like. Like most of the rest of the family, Pteryx are very small and live in rotting vegetative matter. They prefer rotting wood and are generally found under the bark of rotting logs or stumps.

Baeocrara is a genus of featherwing beetles named because of the intricate structure of their flight wings, which have a long fringe of hairs on their borders. They belong to the Ptiliidae family, and are minute: between 1 and 0.5 mm. They are mostly found in hollow fir stumps and other types of rotten wood, dung and plant detritus. They feed on fungal spores. They seem to be recent immigrants to Northern Europe possibly introduced by the import of sawmill products. They have been reported in the Czech Republic. They are one of the least known groups in the Coleoptera.

Scydosella is a genus of beetles that consists of only one species Scydosella musawasensis. The species is regarded as the smallest free-living insect, as well as the smallest beetle. They are among featherwing beetles, named because of their feather-like spiny wings. It was first discovered in Nicaragua, and described in 1999 by Wesley Eugene Hall of the University of Nebraska State Museum. The initial discovery consisted of very few specimens, and exact measurements were not conclusive. Because of their tiny size, they were difficult to observe under microscope after preservation.

Ptiliodes is a genus of featherwing beetles in the beetle subfamily Ptiliinae tribe Ptiliini.

Ptiliola is a genus of beetles belonging to the family Ptiliidae.

Discheramocephalus is a genus of feather-winged beetles, the smallest beetles on earth, first found in Cameroon. It was originally described in 2007 as a monotypic genus (only a single known species). Six additional species were added in 2008, and two were added in 2013.
