Specimens examined: 4 females, Dakung, Taichung, 12-Nov.-2006; 3 females, Dapun, Chiai, 11-Aug.- 2006; 3 females, Jiasian, Kaohsiung, 27-Dec.-2007, K. W. Huang; ex. Cordia dichotoma Forst. (Boraginaceae) .

Relation to host: Cylindrical gall on the upper surface of leaf and erineum on lower surface of leaf.
