Karnyothrips pacificus Okajima View in CoL

Karnyothrips pacificus Okajima, 2006: 394–396 View in CoL .

This species was described from the Ogasawara (= Bonin) Islands, Japan, based on seven female and 9 male macropterae collected mainly from dead branches. It is somewhat similar to K. robustus View in CoL in having the body uniformly dark brown and antennal segment III with three sense cones. However, it can be distinguished by the following features: antennal segment VIII conical, not constricted basally, widely fused to VII; antennal segment IV darker, basal one-third darker than segment III; metanotal sculpture weaker; anterior margin of pelta rounded. One male listed below in the doubtful specimens from Kanagawa, Japan, has the head somewhat longer, and two females and one male from Australia have the head somewhat broader .

Diagnosis. Dark brown species; femora dark brown with extreme apices yellowish, tibiae yellow; antennal segments I and V–VIII dark brown, segment II yellowish brown, segment III yellow, segment IV brown with base yellowish. Antennal segment VIII conical, not constricted basally; segments III and IV with three (1+2) and four (2+2 +1) sense cones respectively. Maxillary stylets relatively wider apart, wider than one-third of head width apart. Notopleural sutures complete; mesopresternum not divided, boat-shaped; prospinasternum small. Tergite IX S1 setae pointed, a little shorter than tube, S2 longer than tube. Tube about 0.6 times as long as head; terminal setae 1.6–1.7 times as long as tube.

Specimens-examined. Japan, holotype females and paratype females and males from the Ogasawara Islands (see Okajima 2006, p. 396) .

Australia, 1 female and 1 male, Queensland, Brisbane, Indooroopilly , QDPI, on dead leaves and branches, 7.iii.2006, SO ; 1 female, data very similar to above, but on dead branches.
