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.
