Dolichothrips longicollis Karny, 1912: 299 .

( Figs 5 , 26, 31 , 37 )

Based on a single male from the flowers of Macaranga tanarius near Semarang, in central Java, this species appeared to be unique in the genus in the absence of the major midlateral setae on the pronotum ( Fig. 5 ). However, although a few specimens have been studied that lack this pair of setae, including the specimens listed below from Bali, these setae vary in length from 10 to 30 microns among specimens from both Malaysia and Borneo. The mouth cone ( Fig. 37 ) and the pronotum are longer than in most other members of the genus, and the sculpture lines laterally on the pronotum form a distinctive series of almost concentric lines ( Fig. 5 ). However, the setae on tergite IX of males are similar to those of macarangai .
