This paper describes four new species of the genus Wormaldia (Philopotamidae): W. transversa, W. cercilonga, W. cercifurcata, and W. squamosa, all from Burmese amber. They belong to so-called micro-caddisflies, which, together with many other Philopotamidae, Psychomyiidae, and the Hydroptilidae, rarely exceed a wing length of ca. 3.5 mm. These micro-caddisflies obviously dominate the mid-Cretaceous Trichoptera fauna of Burmese amber.
