Takagi, S. 2003a Notes on two Lepidosaphidine scale insects described from Japan (Homoptera, Coccoidea, Diaspididae).. Japanese Journal of Systematic Entomology 9(2): 171-175.

Notes: Long-pending questions about the taxonomic identities of two lepidosaphidine scale insects described from Japan are explained. Mytilaspis (Lepidosaphes) buzenensis Kuwana, 1909, is not identifiable with accuracy on the basis of the original description, whereas the type specimens were lost. It is very close to Lepidosaphes laterochitinosa Green, 1925, especially in having a thoracic incrassitation, but it is distinct from the latter in the incrassation occurring mainly on the dorsal surface. There are, however, other forms that are very similar to these species, requiring further studies on the relationships among all of them. Pallulaspis quercus Takahashi, 1957, is based on the second instar female, which was erroneously interpreted as the adult female by the original author. Circumstantial evidence indicates that it is identical with Lepidosaphes glaucae Takahashi, 1932. Surveys at the type localities are necessary for confirming the suppositions about the identities of L. buzenensis and P. quercus.
