Antennae 8-segmented, III with 1 sense cone, IV with 2 sense cones. Head as wide as long, without long postocular setae; ventrally with labrum and clypeus fused together. Pronotum with only 2 pairs of major setae; prosternal ferna large. Fore tarsus without tooth. Mesonotum with no sculpture medially. Fore wing narrow but swollen at base, without duplicated cilia. Pelta weakly sclerotised, tergites II–VII each with 1 pair of sigmoid wing-retaining setae but these arise near the midline and are directed posteriorly; tergite IX setae S1 & S2 capitate; tube shorter than head. Male similar in colour to female; fore femur with stout spur on inner margin, fore tarsus with small pointed tooth, fore tibia with about 3 small tubercles on inner margin. Tergite IX setae similar to female, sternite VIII without pore plate.Related speciesThere is only one species in this genus. The form of the head, with the labrum fused to the clypeus without any trace of a membrane or suture between them (Bhatti, 1998), has not been reported for any other thrips.Biological dataFound on many different plants that are infested by scale insects, this thrips is predatory on the larvae of scale insects and whitefly (Palmer & Mound, 1991).Distribution dataPossibly originally from southern China, but now widespread in tropical and subtropical countries.Family namePHLAEOTHRIPIDAE, PHLAEOTHRIPINAESpecies nameAleurodothrips fasciapennis (Franklin) Original name and synonymsCryptothrips fasciapennis Franklin, 1908: 727 Cephalothrips spinosus Bagnall, 1909: 174 Aleurodothrips fasciiventris Girault, 1927: 2.ReferencesBhatti JS (1998) New structural features in the Order Tubulifera (Insecta). 1.
