The trichopteran family Odontoceridae is reported in mid-Cretaceous Burmese amber by two genera: the extant Psilotreta, with one described extinct species, P. fossilis sp. nov.; and the extinct Palaeopsilotreta, with five species, two of which are newly found and described here, P. kachini sp. nov., P. succini sp. nov. The two genera are closely related and show great similarities in the venation of the forewings and hindwings, but their males differ markedly in the shape of the antennae. In Palaeopsilotreta the males have bipectinate antennae and in Psilotreta the antennae are simple and filiform.
