Thrips graminaeThrips graminaeThis species is known only from a single female that has not been studied by the present authors.
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). The genus Thrips is the second largest genus in the Thysanoptera, and currently includes, worldwide, about 295 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).
Nothing is known of the biology of this species.
Known only from California.
