Identification. Ochrophara chinensis strongly resembles O. corinna but can be easily distinguished by the anterolaterally protruding humeral angles of the pronotum in O. chinensis ( Fig. 2) ( Zheng and Liu 1987). The four specimens from Japan recorded in this study ( Figs. 1–3) matched well with the description of O. chinensis ( Zheng and Liu 1987) in terms of morphological characteristics, including the genital capsule. Therefore, we identified the specimen from Japan as O. chinensis.

Distribution. Japan (Ryukyu Islands: Okinawa Island, Ishigaki Island); China (Yunnan Province) ( Fig. 4). Although the information is not based on specimens deposited at research institutions, some living individuals similar to O. chinensis have been photographed at Lantau Island, Hong Kong, China and Taiwan (https://www. inaturalist.org/observations?taxon_id=874715).

Biology. In Japan, O. chinensis was attracted to artificial light on Okinawa Island. Adults were collected in May and from July to September ( Zheng and Liu 1987; present study).

Discussion

To date, Ochrophara chinensis has been recorded in only one locality, the type locality of the species in Yunnan Province, China ( Zheng and Liu 1987; Rider et al. 2002). To the best of our knowledge, no species of Ochrophara have been recorded north of the type locality of O. chinensis ( Stål 1871; Kirby 1891; Rider 2006). Therefore, Okinawa Island of the Ryukyu Islands, Japan, is the northernmost locality of the genus ( Fig. 4). Additionally, the Okinawa and Yunnan localities, both located in the Oriental Region, are over 3,000 km apart. Therefore, this stink bug species seems to be widely distributed in the Oriental Region of East Asia, and more localities will probably be discovered in future field surveys.
