Recognition data
Distinguishing features
Both sexes fully winged. Body brown, head with pair of yellow longitudinal areas; legs yellow, mid and hind femora brown; III � V largely yellow; forewing brown but pale at apex and sub-basally, and with submedian area variably lighter. Head reticulate with transverse occipital ridge; ocellar setae III on anterior margins of triangle; three pairs of postocular setae present. Pronotum with no long setae. Mesonotum reticulate on anterior half, lateral setae small. Metanotum reticulate medially, median setae arise medially. Tarsi all 2-segmented. Forewing with two complete rows of setae, posteromarginal cilia wavy. Abdominal tergites weakly reticulate medially, median pair of setae small; posterior margins without a craspedum, VIII with comb of microtrichia laterally; tergite X with longitudinal split almost complete. Male with sternal marginal setae minute. Sternites III � VII with slender transverse glandular area.
Related and similar species
There are eight species recognized in the genus Hercinothrips. Each of these is originally from Africa, but two of them are now widespread. H. femoralis is very similar to H. bicintus (Bagnall), but has the forewings more extensively dark. Hercinothrips species all have 2-segmented tarsi, and both longitudinal veins on the forewing bear a complete row of setae.
