Karnyothrips spinulus Okajima

Karnyothrips spinulus Okajima, 2006: 398–400 .

This species was described from the temperate region of mainland Japan based on 12 female and five male micropterae collected on dead branches. It is easily distinguished from the Asian congeners in having major body setae pointed or bluntly pointed at apices, at least not expanded .

Diagnosis. Body brown; all femora brown, all tibiae pale brown with apices yellowish; antennae brown, but apex of segment II and base of segment III yellowish. Postocular and prothoracic major setae pointed or nearly pointed, sometimes very weakly dilated, but not strongly expanded. Antennal segment VIII very slightly constricted basally; segments III and IV with one (0+1) and two (1+1) sense cones, respectively. Maxillary stylets one-fifth of head width apart. Notopleural sutures complete. Mesopresternum divided into two lateral triangular plates. Basantra large. Tergite IX S1 setae sharply pointed, longer than tube. Tube 0.55 as long as head; terminal setae about 1.5 times as long as tube.

Specimens-examined. Japan, holotype females and paratype females and males (see Okajima 2006, p. 400).
