The internal male genitalic features of two species i.e., Laelia exclamationis (Kollar) and Laelia litura (Walker) of family Lymantriidae have been studied in detail to evaluate their taxonomic significance. A dichotomous key on the basis of these features has also been formulated. The use of these features provides an improvement in taxonomical resolution.
