Described on three females from California and two from Utah (Nakahara, 1994: 98), this species has not been studied by the present authors. It is a dark brown species with no sternal discal setae, but has only two setae distally on the forewing first vein.
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. paramadronii has been compared to the more common Californian species, T. madronii (Nakahara, 1994: 98).
