(2015b) . Zootaxa 4054(1): 16. Type material: NCHU ( holotype ), paratypes in NCHU, PHMBL, and USNM. Material examined (13 and 38): Deposited in ZAFU and UB with the following data: Taohuacun, Dabie Mountain, Yin, Huanggang ( Hubei ), Ex unknown gall, unknown tree, ( 23.vi.2014 ) 25.vii.2014 (18 deposited in ZAFU ); Du Mountain ( Guizhou ), Ex unknown gall, unknown tree, 27.vi.1980 , Shengxhen Zhou leg. (18 deposited in ZAFU ); West Tianmu Mountain, Lin’an, Hangzhou ( Zhejiang ), Ex unknown gall, Q. stewardiana , ( 07.ix.2010 ) 11.ix.2010 , Rui Guo leg. (13 and 18 deposited in UB ). Diagnosis : Saphonecrus gilvus is characterized by having lateral pronotal carina, which is short and incomplete, weak, indistinct dorsally (pronotum not sharply angled in dorsal view), simple tarsal claws (without a basal lobe), complete notauli and radial cell of the fore wing at most 3.0x as long as wide. Another species shares all these characteristics: S. emarginatus . The main differences between these two species have already been commented (see the diagnosis of S. emarginatus ). Distribution : Taiwan . Taichung county ( Schwéger et al. 2015b ). First record of this species from mainland China ( Guizhou , Hubei , and Zhejiang Provinces). Biology : Reared from undescribed hairy round galls on leaf midribs of Quercus gilva Blume ( Schwéger et al. 2015b ) . The new material examined presented here was reared from unknown galls on Q. stewardiana , as well as from other unknown galls on unknown host trees.
