Distribution. India (Hodkinson 1986): West Bengal (Mathur 1975, as Psylla longigena).

Host plant. Exbucklandia populnea (Hamamelidaceae) .

Comments. Originally described in Psylla, this species is not congeneric with Psylla alni (Linnaeus, 1758), the type species of Psylla . For this reason, it is formally transferred here to Cacopsylla as C. longigena (Mathur, 1975), comb. nov. from Psylla .
