Hercothrips graminicola Bagnall & Cameron, 1932: 417 . Described from Australia , this species is recognized as the senior synonym of C. graminicola , a species known from Africa and India ( Mound & Houston 1987 ). The record of indicus from China was repeated by Mirab-balou et al . (2017) and the specimens studied by Han (1997) have not been re-examined. Han states that the males he studied had sternal pore plates about 40–50 microns wide, whereas indicus has these structures 80–90 microns wide ( Wilson 1975 ). This suggests that the identification of indicus by Han was a misidentification of quadrifasciatus , in which the pore plates of males are also very wide but never much wider than 60 microns ( Fig. 10 ). In addition, the tergal sculpture of quadrifasciatus is distinctive in forming sub-parallel oblique reticles ( Fig. 5 ). This is another member of the genus that is typically found on various grasses. Specimens studied . CHINA , Guangxi , Hezhou ( 24°57′N , 111°55′E ), 3 females and 3 males from wormwood, 16.ix.2015 (Chao Zhao) . Guangdong , Gaozhou , Yuntan ( 23°53′N , 111°10′E ), 11 females and 3 males from grass, 8.ix.2014 (Zhaohong Wang) .
