Two new cocoon-forming beetles (Coleoptera: Cucujoidea: Bothrideridae) from Baltic amber

Bothrideridae is a small family of poorly known beetles comprising four subfamilies (Teredinae, Xylariophilinae, Bothriderinae and Anommatinae) and more than 400 species in 38 genera (Ślipiński et al. 2010). Members of the family are found in all major zoogeographical regions of the world with the majority of diversity in the Old World tropics. Although little is known about the biology, most bothriderids are closely associated with the galleries of wood-boring insects. The members of the subfamily Bothriderinae are ectoparasites and predators as both larvae and adults. Members of the bothriderid subfamily feed on various larvae of wood inhabiting beetles such as Cerambycidae, Buprestidae, Curculionidae, Bostrichidae, Curculionidae, and Ptinidae, Hymenoptera and Lepidoptera. All known larvae of Bothriderinae are hypermetamorphic with an Two new cocoon-forming beetles (Coleoptera: Cucujoidea: Bothrideridae) from Baltic amber
