DOI: . *Corresponding author: phamthai@. INTRODUCTION The cicada genus Macrosemia was erected by Kato (1925b). It belongs to the tribe Cicadini of the subfamily Cicadinae with Platylomia hopponis Kato, 1925 as the type species. In the genus Platylomia, two species, P. kareisana (Matsumura, 1907) and P. matsumurai Kato, 1928, were transferred to the genus Macrosemia by Matsumura (1930) [27] and Kato (1931) [20], respectively. Later, Kato (1932) [21] considered his Macrosemia hopponis to be a form of Platylomia kareisana. Two .
