Tetratoma
Tetratoma is a genus of polypore fungus beetles comprising approximately 25 described species. These small beetles are associated with wood-decaying fungi and are members of the family Tetratomidae within the superfamily Tenebrionoidea. The genus was established by Fabricius in 1790 and is primarily distributed across northern and temperate regions of the Palearctic.
Tragosoma
Tragosoma is a genus of large saproxylic longhorn beetles in the subfamily Prioninae, distributed across the Holarctic region. The genus includes approximately six described species, with Tragosoma depsarium being the most widely studied and the type species. These beetles are obligate deadwood specialists whose larvae develop in the sapwood of conifers, particularly pines. Adults are notable for their robust, somewhat flattened bodies and relatively short antennae compared to other cerambycids. Several species are of conservation concern due to their dependence on specific deadwood microhabitats threatened by modern forestry practices.
