Abstract Brachypsectridae is a small family with four genera and is extremely rare in the fossil record. Here we report a new Brachypsectridae, Cretopsectra pulchra gen. et sp. nov., based on a larva preserved in mid-Cretaceous amber from Myanmar. The genus Cretopsectra is characterized by pointed squamous setae on the back and sides of long head, small antennae, and the second maxillary palp being shorter than the others. Our discovery represents the first definite Mesozoic larval record of Brachypsectridae.
