The family Cretapsychidae (Insecta, Trichoptera) from mid-Cretaceous Burmese amber, with descriptions of two new species

The Cretaceous family Cretapsychidae Wichard, 2021 belongs to the superfamily Sericostomatoidea Stephens, 1836 and is characterized by the five-segmented maxillary palps, with the second segment being the longest and the following three segments becoming successively smaller, and the tibial spur formula 2/2/4. In addition, the wing venation is characterized by apical forks II, III, and V in the forewings and forks I, III, and V in the hindwings.
