Ordo: Thysanoptera
Familia: Phlaeothripidae
Name
Megalothrips Uzel – Wikispecies link – Pensoft Profile
Remarks
Of the eight species included in this genus, only Megalothrips roundus is recorded from China. The significance of four genera in the subtribe Idolothripina, Bactrothrips, Megalothrips, Megathrips, and Meiothrips, remains problematic (Dang and Qiao 2012a[1]), and further studies are needed on the inter-relationships between the Holarctic and tropical faunas. The species of Megalothrips are identified by their remarkably elongate stylets which are close together medially, but they share other character states with Bactrothrips and Megathrips species.
Diagnosis
Head much longer than broad, without prominent projection in front of eyes; eyes small; 1 pair of postoculars short, 1 pair of interocellars well-developed, and 1 pair of vertex setae usually longer than postoculars; stylets elongate, reaching eyes and close together; antennae 8-segmented, segment III with 2 sensoria, IV with 4; pronotal setae vary, anteroangulars close to midlaterals, notopleural sutures reduced; basantra present; mesopraesternum developed; metathoracic sternopleural sutures absent; fore wings with duplicated cilia; fore tarsal tooth absent in both sexes; pelta hat-shaped, with two slender lateral lobes narrowly fused; abdominal tergites II–VII each with 2 pairs of sigmoid wing-retaining setae; tergite VI with a pair of tubercles laterally in male; tube with prominent lateral setae; anal setae shorter than tube.
