Mesandrothrips subterraneus (Crawford JC)

( Figs 5 , 9 , 18 )

Haplothrips subterraneu s Crawford JC, 1938: 41. Described from England and Japan, this species was also recorded from Korea and the Netherlands with the biological information of injuring lily bulbs and as a predator of Liothrips vaneeckei ( Kurosawa 1938; Okajima 2006). Specimens from China identified as M. subterraneus have antennae uniform brown, postocular seate longer than eyes, major body setae expanded at apex, and prothoracic anteromarginal setae reduced to minute as described by Okajima (2006). The species is recorded from China (Guangdong, Yunnan) for the first time based on five females from unknown grasses. The structural characters are very similar to M. inquilinus , but it differs in antennal segment VI uniformly brown ( Fig. 18 ) and all tibiae yellow ( Fig. 18 ). Whereas M. inquilinus has the antennal segment VI brown with basal half yellow and at least mid- and hind tibiae brown ( Fig. 19 ).
