Majerthrips Mound & Minaei

Only one species is known in this genus, M. barrowi , described from Barrow Island in Western Australia ( Mound & Minaei 2006). This taxon ( Fig. 28 ) was described as related to Holothrips in the Docessissophothripini, because the maxillary stylets are broader than in typical Phlaeothripinae , but the most closely related genus is probably Asemothrips .

Diagnosis. Body strongly reticulate; head about twice as long as wide, elevated in mid-line, postocular setae capitate; stylets retracted to eyes, close together medially; antennae 8-segmented, III with one sensorium, IV with 3 sensoria, VII broadly joined to VIII; pronotum with 4 pairs of capitate setae, anteromarginals reduced; notopleural sutures complete; basantra absent; mesopraesternum complete but eroded or separated into 3 parts; sternopleural sutures long; fore tarsal tooth present in both sexes; wings variable, absent, short or long; pelta variable from Dshaped to narrowly bell-shaped; tergites II–VI usually each with 2 pairs of wing-retaining setae, also one pair of capitate posteromarginal setae; tergite IX postermaginal setae capitate in both sexes; tube much shorter than head; sternites III–VI with worm-like reticulated areas anterolaterally in both sexes.
