The genus Thrips is the second largest genus in the Thysanoptera, and currently includes, worldwide, about 285 species. All members of the genus lack ocellar setae I on the head, and they all have ctenidia on tergite VIII posteromesad to the spiracles. Other characters, such as number of antennal segments, number of setae on the fore wing veins, and number of discal setae on the sternites are variable between species (Palmer, 1992; Mound & Masumoto, 2005). T. graminae is stated to differ from T. konoi in having the metanotum reticulate medially, and in having the antennal segments uniformly brown (Nakahara, 1994: 62).
