Five of them are from Africa, but even the nine New World species in the key provided by Mound and Marullo (1996) , are curiously diverse. No species of Malacothrips has yet been recorded from Australia , but two specimens in ANIC, from the Northern Territory near Darwin, appear to represent this genus ( Fig. 29 ). Diagnosis. Head longer than wide, cheeks with weak setae; postocular setae long, capitate; stylets usually about one fifth of head width apart; antennae 8-segmented, VIII with basal neck, III with 3 sensoria, IV with 4; pronotum usually with 4 pairs of slender, capitate setae, anteromarginals reduced; notopleural sutures complete; basantra present; mesopraesternum variable; sternopleural sutures present; fore tarsi usually with tooth in both sexes; fore wings weakly constricted medially, with or without duplicated cilia; pelta bell-shaped; tergites II–VII each with 2 pairs of wing retaining setae; tube shorter than head, anal setae longer than tube; male sternite VIII with or without pore plate.
