The Lamiine subgenus Pseudale Schwarzer, 1925 from Korean peninsula is reviewed. Along with the only recorded species Pterolophia (Pseudale) jiriensis Danilevsky, 1996, we found two additional new species based on morphological and genital difference. Descriptions, photographs of habitus and male genitalia of each species and a key to species of Korea are provided herein. Hence, genital variation of 4 different geographical populations of Pterolophia (Pseudale) jiriensis is discussed.
