Ufo rufiventris Wang, Guo, Wang, Pujade-Villar and Chen, 2016

Ufo rufiventris Wang, Guo, Wang, Pujade-Villar and Chen, 2016 in Wang et al. (2016). Entomotaxonomia 38 (2): 222. Type material: ZAFU.

Diagnosis: See Wang et al. (2016).

Distribution: Mainland China. Zhejiang Province ( Wang et al. 2016).

Biology: Undetermined galls on the underside of leaves of Q. acutissima ( Wang et al. 2016) . The galls are probably induced by a species of Cerroneuroterus , according to the pictures provided by Wang et al. (2016: 225).

Remarks: After examining the type material of this species (the holotype and one paratype, both females) and checking the original description ( Wang et al. 2016: 222), we noticed that some morphological characteristics were incorrectly mentioned: pedicel of antenna in U. rufiventris is 1.5x as long as wide, which is correct in the main text of the description but incorrect in the drawing given by the authors, where the pedicel is more than 2.0x as long as wide; also the ratio pedicel/F1/F2 is incorrect; the mesoscutum finely coriaceous, with some weak striae and punctures (which are absent in the description); notauli are incomplete, reaching at most 1/3 or 1/2 of the mesoscutum length, and not complete as stated in the original description; parapsidal and anterior lines are visible, however, shallowly impressed, but not absent as stated in the original description; the radial cell is at most 2.5x as long as wide, and not 2.8 as mentioned in the description; and Rs vein is not straight, but slightly curved at the terminal end.
