Caliothrips quadrifasciatus (Girault)

( Figs 2, 5, 8, 10 , 33–34 )

Sericothrips quadrifasciatus Girault, 1927: 1 .

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) .
