Ufo koreanus Melika, Pujade-Villar & Choi

Figs 40–47

Diagnosis. For Ufo koreanus three female paratypes were designated originally: two with the same labels as the holotype, and one female labelled: KOREA, NIAST, 10. Oct. 1997. YPT. J. Y. Choi (Melika et al. 2007). Detail examination of U. koreanus holotype and paratypes showed that the one female paratype labelled “ KOREA, NIAST, 10. Oct. 1997. YPT. J. Y.Choi” belongs to the herein newly described species, Ufo cerroneuroteri .

Females emerged at the beginning of October from leaf spangle galls of Cerroneuroterus nawai (Ashmead), on Q. variabilis (Melika et al. 2007) . Ufo koreanus differs from U. cerroneuroteri by incomplete notauli, extending the most to the half length of the mesoscutum; the median mesoscutal line absent and the 2nd metasomal tergite not incised posterodorsally (Fig. 44). Also U. koreanus differs from U. nipponicus by the head ovate in anterior view (Fig. 40)(trapezoid in U. nipponicus, Fig. 18) and F 1 in the female antenna 1.4´longer than the pedicel (Fig. 42) (2.0´in U. nipponicus, Fig. 22).

Distribution. Known from Republic of Korea, Suwon, Mt. Yeo Gi (Melika et al. 2007).
