Cretaceous caddisflies (Trichoptera: Polycentropodidae) in mid-Cretaceous amber from northern Myanmar

A new species of caddisfly, Neucentropus wichardi sp. nov., from the Neureclipsis cluster in the Polycentropodidae Ulmer, 1903 is described from the mid-Cretaceous amber of Myanmar. The original description of Electrocentropus dilucidus Wichard, 2021 is modified with further features. The absence of forewing fork IV and the fusion of the Sc and R1 before reaching the wing margin in both forewing and hindwing of Electrocentropus indicate that the genus is probably the sister group of all other genera of the Neureclipsis cluster. The fossil findings of Polycentropodidae from different geological periods are summarized in tabular form. The comparison shows a high diversity in the Cretaceous of the Neureclipsis cluster, but declined after the Mesozoic and was afterwards replaced by the strong Polycentropus cluster and the Cyrnus cluster.
