The 3 to 3.5 mm large polypore fungus beetle Tetratoma ancora (family Tetratomidae) is one of three representatives of the genus in Germany. The species are characterized by their 4-membered club of the antenna, which is also reflected in the scientific name of the family. T. ancora can be easily distinguished from the sister species T. fungorum and T. desmaresti by the variable yellow markings on the elytra. The distribution ranges from Central Europe to the far north of Europe and Russia. The species develops on branches of deciduous trees, especially beech (Fagus), oak (Quercus), maple (Acer) which are infested by crust fungi (Corticium), occasionally bitter oyster (Panus stipticus) and turkey tail (Coriolus versicolor). In Germany, T. ancora is widespread, but rare (RL 3). (CB)
