The winged imago of Prorhinotermes japonicus (Holmgren 1912) is described herein for the first time. The soldier caste and two morphs of the neotenic caste also are redescribed. Based on the similar morphology of soldier, alate and neotenic, two Chinese species, Prorhinotermes xishaensis Li & Tsai 1976 and Prorhinotermes hainanensis Ping & Xu 1989, are reverted to junior synonyms of P. japonicus. The current distribution of P. japonicus includes tropical islands surrounding the northern part of the South China Sea. Another Chinese species, Prorhinotermes spectabilis Ping & Xu 1989 from Yunnan Province and two Philippines species, Prorhinotermes tibiaoensis (Oshima 1920) and Prorhinoternws gracilis Light 1921, were compared and included in discussion.

Kalotermes inamurae Oshima 1912 (Isoptera: Kalotermitidae) is reassigned to Incisitermes (Krishna, 1961) based on the winged imago that is described herein for the first time. The two size morphs of the soldier caste are redescribed, as is the distinctly different morphology of the soldier of incipient colonies. The distribution of L inamurae is restricted to the tropical zone of Taiwan. Another tropical species, Incisitermes mcgregori (Light), from Luzon, Philippines, has similar soldier morphology and may be a junior synonym of L inamurae. The five Incisitermes species reported in Japan, China, Taiwan, and the Philippines were compared morphologically. [ABSTRACT FROM AUTHOR]
