Antennae 8-segmented; segment III with three sensoria, IV with four sensoria; VIII constricted to basal neck. Pronotum reticulate, weakly medially, with five pairs of capitate major setae; basantra absent. Fore tarsus with tooth. Metanotum reticulate. Forewings parallel sided, with more than 30 duplicated cilia; sub-basal setae S3 finely acute, S1 & S2 capitate. Pelta triangular with sinuate lateral margins, reticulate; tergites II � VII each with two pairs of slender sigmoid wing-retaining setae; tergite IX setae S1 shorter than half of tube length.

Related and similar species
More than 20 names are listed under the genus Phlaeothrips, but many of these are old names for which specimens are not known to exist. Only one member of the genus is known from North America, presumably introduced to California from Europe. The listing of "Phlaeothrips karnyi " by Hoddle et al. (2004) was an error; that species is here listed correctly in the genus Hoplothrips.
