Remarks. It is a common species widely distributed in China. It is not easy to separate the females on morphological characteristics from P. rothneyi without having males. However, the character of body colour generally works well: in P. jokahamae the body is black, with orange yellow markings and with reddish brown patches along the margin of markings especially along the bands of second to sixth metasomal tergites; in P. rothneyi the body is generally black with yellow markings. The stripes on the mesoscutum vary from narrow to wide. Generally the longitudinal yellow stripes on the propodeum present in the specimens from southern China ( Fig. 18 C–D), while almost entirely absent in the specimens from northern China ( Fig. 18 A–B). Some specimens especially females in the collections of MNHN and RMNH labelled as Polistes hebraeus Fabricius are misidentified. Liu (1937) listed P. macaensis var. perkinsii Kohl and P. jokahamae Radoszkowski. Lee (1985) included P. jokahamae , P. jadwigae and P. hebraeus , however, only based on minor colour differences according to the key. His identifications need to be reconfirmed. We concur with the synonymies listed by Carpenter (1996) and Kojima & Hagiwara (1998).

Distribution. China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Henan, Hebei, Jiangsu, Jiangxi, Jilin, Shaanxi, Sichuan, Shanghai, Zhejiang, Hong Kong, Taiwan); India; Japan; Korea; Malaysia; Mongolia; Society Islands: Bora, Tahiti; Tuamotu Archipelago; introduced into Hawaii; Vietnam.
