摘要

A new monotypic family, †Yantarocentridae (Insecta, Trichoptera), is described from Baltic amber. The type species, Yantarocentrus gusakovi gen. et sp. nov., is a male showing good preservation of its head, palps, antennae and legs; the forewings are partially seen and the genitalia are faintly visible with translucent light. New characters of antenna have been introduced for the separation of this family from related taxa. The combination of characters shows the new family to be placed as a sister lineage of higher Plenitentoria, including Lepidostomatidae, Brachycentridae and Limnephiloidea. Some features, such as peculiar sensory fields on the antennae, are not found elsewhere in Trichoptera.
