(33 and 38 deposited in ZAFU, 23 and 28 deposited in UB); Qingliangfeng, Lin’an, Hangzhou (Zhejiang), Ex unknown gall, Q. glauca , emerged 15.iv.2013 (43 and 88 deposited in ZAFU, 13 deposited in UB); Longtang Mountain, Hangzhou (Zhejiang), Ex unknown gall, Q. stewardiana , (15.iv.2013) 05.vii.2013, Shijun Wang leg. (43 and 108 deposited in ZAFU, 23 and 28 deposited in UB); Changhua Town, Hangzhou (Zhejiang), Ex unknown gall, Q. stewardiana , emerged 02.vii.2013 (68 deposited in ZAFU, 28 deposited in UB); Tianmu Mountain (Zhejiang), Ex unknown gall, unknown tree, emerged 05.iv.2015, Jie Shen leg. (13 and 18 deposited in UB); same data but collected (12. iv.2015) and emerged 06.v.2015 (18 deposited in UB).

Diagnosis: Saphonecrus globosus belongs to a group of species ( S. longinuxi and S. saliciniai ) that has lateral pronotal carina, simple tarsal claws and incomplete notauli, which reach at most to half length of the mesoscutum. It differs from S. longinuxi by a trapezoid head in anterior view (rounded in S. longinuxi ), pedicel being 1.6x as long as wide (globose, as long as wide, in S. longinuxi ) and F1 1.7x as long as F2 (F1 nearly equal to F 2 in S. longinuxi ). It differs from S. saliciniai by the transfacial distance being as long as height of eye (shorter in S. saliciniai ), POL 2.3x as long as OOL and OOL 1.7x as long as diameter of lateral ocellus (POL 3.0x as long as OOL and OOL just slightly longer than diameter of lateral ocellus in S. saliciniai ), pedicel 1.5–1.6x as long as wide in both sexes (2.1x as long as wide in females, just slightly longer than wide in males in S. saliciniai ) and syntergite without punctures posterodorsally (with a small patch of micropunctures in S. saliciniai ).

Distribution: Taiwan. Nantou county ( Schwéger et al. 2015b). First record of this species from mainland China (Zhejiang Province).

Biology: Reared from undescribed leaf galls on Q. glauca ( Schwéger et al. 2015b) . The new material examined here was reared from unknown galls on Q. ciliaris , Q. glauca and Q. stewardiana .
