Y. Xu. Comments. The species was erected in genus Margituberculatus based on only one alate viviparous female ( Zhang et al. 1992 ). Then the species was removed to the genus Aspidophorodon as Aspidophorodon longituberculatum according to the characters of processes and siphunculi; meanwhile, Aspidophorodon cornuatum was described as a new species ( Chen et al. 2015 ). At that time, there were no alate viviparous females of Aspidophorodon cornuatum , so it was difficult to compare with the two species. After several surveys in southwest China, apterous viviparous female (Fig. 18C ) and alate viviparous female (Fig. 18D ) of Aspidophorodon cornuatum were collected. The alate viviparous female of Aspidophorodon cornuatum is with marginal processes on abdominal tergites I-IV (Fig. 18E ) which is the same as Aspidophorodon longituberculatum (Fig. 18A, B ). The molecular data of alate viviparous females of Aspidophorodon longituberculatum and apterous viviparous females of Aspidophorodon cornuatum support they are the same species (Fig. 23 ). So, Aspidophorodon cornuatum Qiao, 2015 should be considered as junior synonym of Aspidophorodon longituberculatum (Zhang, Zhong & Zhang, 1992). Figure 18.

E dorsal view of abdomen of Aspidophorodon cornutum Qiao, 2015 syn. nov. Scale bars: 0.10 mm. Aspidophoron being neuter, the adjectival specific epithet is also neuter, so longituberculatus is revised as Aspidophorodon longituberculatum . Host plant. Salix cupularis . Distribution. China (Yunnan, Tibet). Biology. The species occurs on the undersides of leaves along the main vein of host plants (Fig. 21B-E ).
