Karnyothrips robustus Okajima, 2006: 396–398 View in CoL .

This species was described from the Ryukyu Islands (Ishigaki Is. and Iriomote Is.), Japan, based on many female and male macropterae collected from dead leafy branches. In the original description it was also recorded, but listed under non-paratypic specimens, from the Ryukyu Islands (Amami Is., Okinawa Is. and Miyako Is.) and Taiwan. It is here newly recorded from Indonesia, Thailand and Vietnam. Although specimens from Vietnam are very similar to the type series, specimens from Indonesia and Thailand are somewhat different especially in the tergite IX S1 setae. These are expanded at apices and a little shorter than the tube in the specimens from Japan, Taiwan and Vietnam, though those of specimens from Indonesia and Thailand are variable, mostly longer and pointed or bluntly pointed, but infrequently weakly expanded and shorter. However , they are not distinguishable from the type series in coloration and most other structures. One female listed below in the doubtful-specimen from Peninsular Malaysia is very similar to robustus View in CoL , but has somewhat darker antennal segments and broader head proportions .

Diagnosis. Dark brown species with somewhat large body ( Fig. 32 View FIGURES 31–40 ); femora dark brown with extreme apices yellowish, tibiae yellow; antennal segments I and VI–VIII dark brown, segment II pale brown with apex yellow, segment III yellow, segment IV brown with base yellowish, segment V brown with extreme base yellowish.Antennal segment VIII weakly constricted basally ( Fig. 186 View FIGURES 182–187 ); segments III and IV with three (1+2) and four (2+2 +1) sense cones respectively. Maxillary stylets about one-fourth of head width apart ( Fig. 182 & 183 View FIGURES 182–187 ). Notopleural sutures complete; mesopresternum not divided, boat-shaped; prospinasternum small ( Fig. 184 View FIGURES 182–187 ). Metanotum distinctly sculptured with reticulation. Tergite IX S1 setae expanded, a little shorter than tube, S2 pointed, much longer than tube. Tube about 0.6 times as long as head; terminal setae about 2.0 times as long as tube.
