Plaukelius

Plaukelius is a extinct genus of beetles in the family Trogossitidae. It is a part of the family of masked beetles, which includes flat, dark-colored beetles that are often found in deadwood and under bark. These beetles are typically nocturnal and are known for their ability to secrete a chemical that helps to deter predators.

The Plaukelius genus was first described in the late 18th century by the Swedish entomologist, Carolus Linnaeus. It is composed of a small number of species, which were initially thought to be part of other beetles genera, due to their similarities. However, they were later recognized as a distinct group due to specific characteristics that set them apart from other beetles.

Little is known about the biology of the Plaukelius genus, but based on its physical characteristics and mannerisms, it is believed to have been a relatively small beetle with a dark coloration. As with other beetles in the Trogossitidae family, it is likely that Plaukelius beetles lived in deadwood or under bark, where they could be protected from predators and parasitoids.

Despite the detailed descriptions of the Plaukelius genus, its fossil record is scarce, with few preserved specimens found. As a result, much of what is known about this beetle comes from general descriptions of beetles in its family, making it challenging to study and understand in great detail. Due to the lack of information, the Plaukelius genus is considered an extinct group of beetles, with no living representatives found in modern times.
