Coryphothrips Karny

( Figs 105, 107 )

Coryphothrips Karny, 1923: 340 . Type species: Coryphothrips trochiceps Karny , by original designation.

This genus remains known only from the original specimens of two species, taken from galls on Dipterocarpus species , one from Thailand but the other from Malaysia. Judging from the body sculpture, and the finely hairy tube, Coryphothrips is probably related to Gynaikothrips and Gigantothrips , despite having only two sensoria on the fourth antennal segment. However, the ocellar region of the head is prolonged into a conical projection over the bases of the antennae ( Fig. 105 ), with the fore ocellus on the ventral surface of this projection.

Diagnosis: Body suface with prominent sculpture lines ( Figs 105, 107 ); head longer than wide, anterior margin cone-shaped, projecting over antennal bases ( Fig. 105 ); eyes without enlarged ommatidia, two pairs of postocular setae, one behind inner margin of eyes, one posterolaterally; maxillary stylets wide apart, retracted half-way to postocular setae; antennae 8-segmented, III with 1 sensorium, IV with 2; pronotal epimeral setae long, other major setae short and stout, notopleural sutures complete or nearly complete ( Fig. 107 ); basantra absent; mesopresternum transverse; sternopleural sutures absent; fore tarsal tooth absent in both sexes; fore wings parallel-sided, without duplicated cilia; pelta triangular; tergites II–VII with 2 pairs of wing-retaining setae, III–V with one pair of anterior accessory wing-retaining setae; tube with straight sides, with fine lateral setae, longer than head; male sternite VIII without pore plate.
