( Figs 43, 44 )

Habrothrips Ananthakrishnan, 1968: 137 . Type species: Habrothrips curiosus Ananthakrishnan , by monotypy.

The single species in this genus was described from India, but subsequently recorded from Taiwan, Malaysia, and Australia, living in leaf-litter and on dead twigs. Habrothrips is similar to other genera in the Urothripini in having abdominal segment IX more than twice as long as segment VIII, and the tube long and slender with elongate anal setae. However the form of the head is distinctive.

Diagnosis: Body tuberculate ( Figs 43, 44 ); head strongly produced in front of eyes ( Fig. 43 ), with a pair of well-developed setae, cheeks swollen just behind eyes, constricted to base; postocular setae minute; stylets retracted to postocular setae, close together medially; antennae 8-segmented, III with 3 sensoria, IV with 4; pronotum with epim setae developed, other major setae reduced, notopleural sutures reduced ( Fig. 43 ); basantra and mesopresternum reduced; sternopleural sutures absent; fore tarsal tooth absent in both sexes; fore wings slender, without duplicated cilia; pelta complete; tergites II–VII with 2 pairs of fan-shaped wing-retaining setae ( Fig. 44 ); tergite IX and tube elongate, tube much longer head, anal setae about twice as long as tube.
