Heterothrips Hood

Heterothrips Hood, 1908 . Type-species H. arisaemae Hood.

Diagnosis. Antennae 9-segmented, segments III–IV with circumpolar sensoria at apex, with one or more rows of sensorial pores; III with two basal constrictions. Head wider than long, without long setae; ocellar setae I present or absent. Pronotum with no long setae ( Fig. 14 ); metanotum covered with microtrichia, usually with concentric sculpture but sometimes almost forming a triangle medially ( Fig. 12 ). Fore wing slender, wider at base, both veins with complete rows of setae ( Fig. 20 ). Abdominal tergites laterally covered with microtrichia, with posteromarginal fringe of independent microtrichia (Fig. 1), or with craspedate lobes bearing microtrichia; II–VIII with median pair of setae well developed, arising close together (Figs 2, 17, 19); sternites sometimes bearing few discal setae. Male usually with oval or transverse pore plates on abdominal sternites ( Figs 54 , 67 ); some species with a pair of dorsolateral finger-like projections on tergite IX ( Figs 81 , 107 ).
