This publication treats species withinTheopeaand closely allied genera that were not covered in the previous two revisions. Three species ofTheopeaBaly, 1864 are treated herein, withT. bicolorKimoto, 1989 andT. mouhotiBaly, 1864 redescribed, andT. bicoloroidessp. nov.described. A new genus that we consider closely related toTheopea,Pseudotheopeagen. nov., is described. This new genus can be recognized with the presence of reticulate microsculpture on the vertex of the head and pronotum and presence of an apical spine on each metatibia. The following species are transferred toPseudotheopeaas new combinations:Theopea aeneipennisGressitt & Kimoto, 1963,T. azureaGressitt & Kimoto, 1963,T. clypealisMedvedev, 2015,T. nigritaMedvedev, 2007,T. smaragdinaGressitt & Kimoto, 1963,T. similisKimoto, 1989, andT. subviridisMedvedev, 2012.Theopea subviridisMedvedev, 2012 is regarded asnew synonymofPseudotheopea similis(Kimoto, 1989). In addition, six new species ofPseudotheopeaare described:P. borerisp. nov.from India,P. gressittisp. nov.from Philippines,P. hsingtzungisp. nov.from Laos,P. kimotoisp. nov.from Laos, Thailand, and Vietnam,P. leehsuehaesp. nov.from Laos, andP. sufangaesp. nov.from Taiwan. A second new genus regarded as closely related toPseudotheopea,Borneotheopeagen. nov., can be recognized by possessing uniform antennae in both sexes and lacking an apical spine on each metatibia. Two new species ofBorneotheopeaare described from Borneo:B. jaklisp. nov.andB. kalimantanensissp. nov.
