Diagnosis: Altihoratosphaga montivaga ( Fig. 7C, F ) is closely related to both A. nou and A. hanangensis sp. nov. All three species share the black spots on the tegmina, and a verrucose pronotal disc. The males of A. montivaga are of similar size to males of A. nou and A. hanangensis sp. nov., whereas the females are generally larger than the females of the two latter species. Both males and females of A. nomima are considerably larger than those of A. nou and A. hanangensis sp. nov., but the females are of similar size to those of A. montivaga .
