Chrysodema (Chrysodema) lewisii lewisii Saunders, 1873

( Figs 1G–I , 5C )

Chrysodema lewisii Saunders, 1873: 510 .

= Chrysodema oschimana Nonfried, 1895: 297 .

Material examined. 1 ♂ ( Fig. 1G–I ) ( CHTS): JAPAN, Yonaha Mountain, Kunigami , Okinawa; 8–9.VIII.2016; Hao Xu & Jian-Yue Qiu leg.; body length 1.93 cm, width 0.67 cm, length/width ratio: 2.88; aedeagus ( Fig. 5C ) length: 4.95 mm, width: 1.26 mm, length/width ratio: 3.93 .

Distribution. Japan (Hachijô and Tsushima islands south to Miyako Island) ( Frank & Sekerka, 2020).

Adult host plant. Castanopsis sieboldii sieboldii , Lithocarpus edulis , Quercus phillyreoides , Quercus spp. ( Ohmomo & Fukutomi, 2013).

Remarks. According to Frank & Sekerka (2020) the specimen above can certainly be identified as C. (C.) lewisii lewisii by the habitus characters and distribution, but the characters of aedeagus is obviously similar to C. (C.) lewisii nakatai . Since the apices of parameres also exhibit variation in C. (C.) hainanensis sp. nov., we consider the elytral characters sometimes more significant than the apices of parameres. Hence, we finally identified the specimen as C. (C.) lewisii lewisii . Whether the two subspecies of C. (C.) lewisii should be divided into more subspecies or synonymised may need further research with molecular methods.
