( Figs 10 , 21 , 69–73 )

Aeolothrips (Coleothrips) vittatus Haliday, 1836: 451 .

Diagnosis. Female macroptera. Body uniformly dark brown ( Fig. 10 ); antennal segments I–II dark brown, III yellow with apex shaded, IV yellowish brown with apex shaded, V–IX brown; fore wings with subbasal dark band elongate along posterior margin, elongate dark area extending beyond second vein, apex white, extreme base slightly shaded, vein not shaded on pale area ( Fig. 21 ); all legs dark brown, tarsi slightly paler; prominent body setae brown. Head arched at cheeks ( Fig. 69 ). Antennal segment V about 1.3 times as long as the combined length of VI–IX ( Fig. 70 ). Antennal segments I to IX ratio length/width as follows: 1.0, 1.7, 3.9, 3.2, 2.6, 1.0, 0.6, 1.0, 1.7. Pronotum 0.7 times as long as wide, weakly sculptured along posterior margin, smooth medially, with about 25 small discal setae and no long and stout setae. Mesonotum with lateral setae subequal in length to median pair of setae; anteromedian CPS present or absent. Metascutum with polygonal or longitudinal reticulations medially; CPS present or absent, rarely only one CPS ( Fig. 71 ). Abdominal tergite I with posteromedian CPS; tergite IX usually with a minor seta between S1 setae; sternite VII with two pairs of accessory setae far from posterior margin between S1 and S2 setae ( Fig. 72 ). Spermatheca with several distinct internal teeth ( Fig. 73 ).

Male. Unknown.

Specimens studied. JAPAN, Honshu, Nagano Pref., Sugadaira: 2 females on Picea jezoensis [ Pinaceae ], 17.vi.1973, K.Haga (TUA). 1 female on Picea jezoensis , 20.vi.1973, K.Haga (TUA). 1 female on Larix leptolepis [ Pinaceae ], 19.vi.1995, T.Tsutsumi (FU), 1 female on Larix leptolepis , 22.vi.1995, T.Tsutsumi (FU). Kanagawa Pref., Kawasaki City, 4 females on Pinus sp. [ Pinaceae ], 7.vi.2007, M.Masumoto (TUA).

Remarks. This species is widespread in the Holarctic region. In Germany, it has been reported as a probable predator of Thrips pini, a species associated with Pinaceae ( Lewis 1973) .
