Primitive Ghost Moths: Morphology and taxonomy of the Australian genus Fraus Walker (Lepidoptera: Hepialidae s. lat.)

Beyond describing and illustrating a primitive hepialid, these observations are intended to serve as reference for the study of the classification of Hepialoidea and lower Lepidoptera.
