The lerp-forming psyllids is very common in the Australian region, such as Spondy?iaspis (Signore, 1879), Cardiaspina (Crawford, 1911), Glycaspis and Hyalinaspis (Taylor, 1960), all of them with bipartite proctigers in the males. On the basis of some morphological and biological characters they should stand for a peculiar subfamily Spendyliaspinae of the Psyllidae (Heslop-Harrison, 1954). In the Palaearctic region two Japanese species were identified as Pachypsylla japonica and P. usubai by Y. Miyatake (1968, 1980) recently, and the nymph, the gall the lerp collected by F.
