The Oleaceae-feeding lace bugs of the genus Perissonemia from Japan (Hemiptera: Heteroptera: Tingidae)

The present study revises the taxonomy of the lace bug genus Perissonemia Drake & Poor, 1937 (Hemiptera: Heteroptera: Tingidae: Tinginae) from Japan. Three species are recognized and (re)described: P. occasa Drake, 1942 from Honshu, P. okinawensis sp. nov. from the central part of the Ryukyu Islands, and P. yaeyamensis sp. nov. from the southern part of the Ryukyu Islands. Previous records of P. occasa from the central and southern parts of the Ryukyu Islands are confirmed as misidentifications of P. okinawensis sp. nov. and P. yaeyamensis sp. nov., respectively. The host plant relationships are discussed for P. occasa and P. yaeyamensis sp. nov. Photographs of living individuals of P. occasa and P. yaeyamensis sp. nov. are presented. A key is provided to facilitate the identification of the three species of Perissonemia distributed in Japan.
