Аннотация: The anatomy and genitalia of a larviform female were studied for the first time in the familyLycidae. The structure of the exo- and endoskeleton of a Platerodrilus female was found to be notmuch different from that of its larva, with external genital appendages barely differentiated. Thereproductive system was found to include an unpaired spermatheca, and paired oviducts and ovaries.The structure of the integument was found to also be peculiar, with two layers of cuticle differingin structure. On the other hand, the labrum and mandibles were found to be quite unlike the larvalones: the labrum was undivided and the mandibles fully metamorphosed. This odd combination ofmorphological characters may be interpreted in two ways. First, it may be hypothesized that this is apupa. However, its genital appendages are simpler than those of “normal” Lycidae pupae; wings ortheir rudiments are completely absent; there are very few features of imaginal morphology in theexternal structure. Therefore, we propose another hypothesis—this is the stage preceding the pupa,which Hinton (1946) designates as ‘prepupa’.
