Thrips coloratus Schmutz

( Figs. 90–97 )

Female macroptera. Body bicoloured, head to thorax yellow to brownish yellow, abdominal segments yellow or brownish yellow with median half of tergites II to VIII ( Fig. 93 ) and segments IX to X dark brown; antennal segments I to III yellow, IV to VII dark brown often with basal third to half pale; fore wings brown with basal fifth including clavus slightly pale; all legs yellow; prominent body setae dark brown. Head ( Fig. 90 ) rounded at cheeks. Ocellar setae III just lateral to fore ocellus. Postocular setae I the longest and much longer than longitudinal diameter of hind ocelli, II and IV minute. Antennae ( Fig. 91 ) 7-segmented. Pronotum ( Fig. 90 ) strongly sculptured with transverse striae, with about 40 discal setae; posteroangular setae 2 pairs; posteromarginal setae 3 pairs. Metascutum ( Fig. 92 ) sculptured with longitudinal striae except anteromedially; median pair of setae behind anterior margin; CPS present. Fore wing first vein with seven basal and three distal setae. Abdominal tergites with small scallops along posterior margin, these scallops distinct on posterior segments; tergite II with 4 lateral marginal setae; tergite VIII ( Fig. 94 ) with posteromarginal comb complete, microtrichia often irregular in length or space; tergite IX with two pairs of CPS; sternite I without microsetae anteromedially; sternites III to VII ( Fig. 95 ) with about 14 (II with 3 or 4) discal setae transversely arranged in nearly straight line; sternite VII with S1 setae far from posterior margin; pleurotergites without discal setae and ciliate microtrichia.

Male macroptera. Body uniformly pale yellow. Antennal segment VI with more 20 setae. Abdominal tergite VIII without posteromarginal comb; tergite IX ( Fig. 96 ) with S1 setae at level of S2 setae and slightly shorter than S2 setae, their bases equidistant; sternites III to VII ( Fig. 97 ) each with an oblong pore plate.

Comments. This species is distributed throughout Japan, Taiwan to India and Australia. It is one of the most common flower-living species in Japan. Female adults of coloratus can be distinguished easily from other species by the body colour. The population on Ogasawara Islands has been considered to be same species although their body is uniformly dark brown in both sexes ( Palmer, 1992), but this is here described as a new species.
