In this paper, we described one new genus Babus gen. nov. from the subfamily of Diptilomiopinae by characters as below: scapular setae (sc) placed ahead of the rear shield margin, anterolateral setae on coxisternum I (1b) absent, tarsal empodium divided, legs with six segment, basiventral femoral setae (bv) and antaxial genual setae (l″) on leg II absent. Two new species, Babus chukrasium sp. nov. collected from Chukrasia tatularis A. Juss. and Babus anisatae sp. nov. from Clausena anisata (Willd.) Hook. f. ex Benth. were herein described. In addition, another new species Trimeroptes chaetophori sp. nov. collected from Rubus chaetophorus Card. was also described and illustrated from the same subfamily. All of new species described here are vagrants on the under surfaces of leaves, and no damage was observed.
