Dolichothrips Karny

( Figs 34, 35 )

Dolichothrips Karny, 1912c: 299 . Type species: Dolichothrips longicollis Karny , by monotypy.

There are 20 species listed in this genus, and these appear to be phytophagous in association with the leaves or flowers of trees and shrubs. Most of the species are described from India, with one from Africa and another from Australia. Four species are recorded from southern China and Taiwan, and one each from Java, the Philippines and New Guinea. D. pumilus Priesner and D. flavipes (Moulton) , described from Taiwan, probably represent the same species. Photographs of the holotype of flavipes (in CAS San Francisco) clearly show that the tibiae are yellow; the statement by Okajima (2006) that the mid- and hind tibiae are dark brown is therefore not correct.

Diagnosis: Head longer than wide ( Fig. 34 ); eyes normal, postocular setae well-developed; mouth-cone long and pointed ( Fig. 35 ), stylets retracted to postocular setae, wide apart, maxillary bridge present; antennae 8- segmented, III with 3 sensoria, IV with 4; pronotum usually with 5 pairs of capitate setae, notopleural sutures complete; basantra present ( Fig. 35 ); mesopresternum eroded medially; sternopleural sutures absent; fore tarsal tooth usually present in both sexes; fore wings weakly constricted medially, with duplicated cilia; pelta triangular or trapezoidal; tergites II–VII with 2 pairs of wing-retaining setae, sometimes with accessory wing-retaining setae; tube with straight sides, shorter than head; male sternite VIII without pore plate.
