New Cretaceous caddisflies from Burmese amber (Insecta, Trichoptera)

Three new caddisflies species are described and illustrated from the mid-Cretaceous Burmese amber: Wormaldia cretacea sp. nov., W. resina sp. nov. (Philopotamidae) and Neureclipsis burmanica sp. nov. (Polycentropodidae). Palerasnitsynus ohlhoffi (Psychomyiidae) is re-described based on new fossils. Wormaldia are common in Burmese amber, and its diversity shows that this genus had very ancient origin and diversified at least during the mid-Cretaceous. N. burmanica sp. nov. is the oldest record of Neureclipsis, revealing this genus originated at least in the mid-Cretaceous. So far, six extinct species representing the small Order Trichoptera have been found in Burmese amber.
