Karnyothrips inflatus Okajima View in CoL

Karnyothrips inflatus Okajima, 2006: 388–390 View in CoL .

This species was described based on a unique holotype macropterous female collected from Ishigaki Is., the Ryukyu Islands, Japan, together with non-paratypic two females and one male collected from the Ryukyus and the Ogasawara Islands. Antennal segment III of this species has a sub-basal ring-like swelling which is very similar to that of two Priesneria species, P. kellyana View in CoL and P. peronis View in CoL from Australia. However, these Australian species have only one sense cone on antennal segment III, whereas inflatus View in CoL has two sense cones. Moreover, K. doliicornis View in CoL from Hawaii, which has often been classified into Priesneria View in CoL , is very closely related to this species. There is a possibility that inflatus View in CoL is a synonym of doliicornis View in CoL , and this requires further study.

Diagnosis. Dark brown species; femora dark brown, tibiae brown with apices yellowish; antennal segments I and IV–VIII brown, IV yellowish at base, segments II and III yellowish, II a little darker than III. Antennal segment III with sub-basal swelling; segment VIII conical, not constricted basally, widely fused to VII; segments III and IV each with two (1+1) sense cones. Maxillary stylets about 1/4 of head width apart. Notopleural sutures complete; mesopresternum reduced, divided into two lateral small triangular plates; prospinasternum wide. Tergite IX S1 setae expanded, shorter than tube, S2 pointed, much longer than tube. Tube about 0.7 times as long as head; terminal setae a little shorter than 2.0 times as long as tube.

Specimens-examined. Japan, holotype female; two other females and one male (see Okajima 2006, p. 389) .
