Saphonecrus gilvus Melika and Schwéger, 2015

Saphonecrus gilvus Melika and Schwéger in Schwéger et al. (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.
