Dolichothrips macarangai (Moulton)

( Figs 7 , 27, 32 )

Neoheegeria macarangai Moulton, 1928: 319 .

Described from Taiwan, where it seems to be quite common, a single male of this species was recorded from the Ryukyu Islands of southern Japan ( Okajima 2006). It is similar in appearance to citripes , but as indicated in the key above the pronotal anteromarginal setae are considerably shorter than in that species. Both species have the setal pair SI on tergite IX dark brown, but in the few available specimens from Thailand the fore wing sub-basal setae S3 are paler than in specimens from Taiwan. The four males studied all have setae S2 on tergite IX scarcely 10 microns long, and much shorter than the iS setae.

Specimens examined. TAIWAN, Kentin , 1 female, 1 male, 13.iv.1993 ; Nantou, 1 female, 4.v.1993, in ANIC ; Wufeng , 1 male, 23.vii.1993, in BMNH . THAILAND, Bangkok, Kasetsart University , 2 females, 2 males on Polyalthia longifolia , 3.vii.2013, in ANIC .
