A, Frontoclypeus and clypeus in lateral view; B, rightantenna; C, left fore leg; D-E, apical part ofabdomen in ventral view (D, f; E, 4).Scales; 2 mm (A, C-E), 1 mm (B).locality (NSMT). The exuviae of this species were first described by Kato (1932); hisdescription is, however, concentrated on the antenna and fore femur as in those of otherspecies that he described.Distribution. Taiwan, S China (incl. Hainan), Indo-China (Vietnam, Cambodia,etc.)This cicada inhabits rather thick forests oflowlands and montane areas, singing in aslow tempo mainly in the morning (about 0800-1100 h), andsometimes attracted to light.This species does not aggregate on certain trees.Cryptotympana kotoshoensis Kato, 1925(Figs. 144. 163-164, 171, 179, 181-184)Cryptotympana kotoshoensis Kato, 1925, Trans, nat.
