Macropterous female brown, tarsi and apices of tibiae yellow, also antennal segments I–III; forewings with sub-basal pale band, then brown but paler toward apex. Head with occipital ridge not close to eyes; ocellar triangle with irregular markings; ocellar setae III on anterior to margins of triangle; three pairs of postocular setae, median pair long. Antennal segment III slender, sensorium short, not extending beyond basal fifth of segment IV. Pronotum densely striate, blotch anterior margin deeply emarginate. Metanotal sculpture mainly transverse, with band of microtrichia on posterior fifth. Forewings with one seta near apex displaced onto second vein from first vein; no sub-apical lobe. Tergites I–VIII densely covered with microtrichia, and with complete posteromarginal comb. Sternites with no discal microtrichia medially, sternites III–VII with lobed craspedum medially bearing long microtrichia. Micropterous female with wing lobe shorter than width of thorax; metanotum with microtrichia on more than half of sclerite. Male with small circular pore plate on sternites IV–VII
Nine species are currently recognised in this genus, from widely different parts of the world. However, the generic classification is thought to be a poor reflection of phylogeny, and Sericothrips appears to comprise species which show some level of wing-length reduction.
