description: Genus Megapomponia Boulard, 2005
Megapomponia Boulard, 2005: 100.
Type species. Cicada imperatoria Westwood, 1842.
Diagnosis
See Boulard (2005) and Lee and Sanborn (2010).
Distribution
Except for an islander, M. merula from Borneo, Megapomponia shows its diversity mainly in mainland Southeast Asia (Lee and Sanborn 2010): M. imperatoria in peninsular Malaysia; M. sitesi and M. clamorigravis in southern Thailand; M. atrotunicata and M. castanea in Cambodia; M. intermedia in Myanmar, Thailand and Indochina; M. pendleburyi in southern Thailand and peninsular Malaysia. The holotype of M. foksnodi was from Chiang Mai, northern Thailand (Boulard 2010). The new species M. macilenta sp. nov. is recorded from southern Vietnam.
Revised key to the species of Megapomponia

Body comparatively small (body length 53.0– 59.5 mm); forewing without infuscation on mediocubital (m-cu) crossvein............................. 2 Body very large (body length 60–75 mm); forewing with distinct infuscation on mediocubital crossvein.................................................. 3
2. Mesonotum mostly dark brown to fuscous without prominent marks; forewing with slightly smoky distal regions along eight apical cells........ M. castanea Mesonotum reddish brown with black spots; forewing without smoky area along hind margin................................... M. macilenta sp. nov.
3. Pronotal collar with at least two pairs of blackish spots laterally........... 4 Pronotal collar without spots............................................ 9

5. Male body length longer than 70mm, wing span usually more than 200mm; male operculum almost one colour, ochraceous; male abdominal tergites and sternites without distinct black marks....................... M. imperatoria Male body length 60–70mm, wing span about 160–180mm; male operculum with broad smoky areas; male abdominal tergites and sternites with a broad black portion........................................................... 6

Primarily active in January and February; calling song high-pitched and consisting of repeated phrases each comprising a long echeme followed by many fragmental echemes........................................ M. pendleburyi Primarily active in November and December; calling song comparatively low-pitched and consisting of repeated phrases each comprising varieties of fragmental echemes...................................... M. clamorigravis
