( Figs. 137–142 )

Female macroptera. Body usually uniformly dark brown, antecostal ridge dark; antennal segments I to II brown, III brownish yellow, IV to V brown with base yellowish, VI to VII brown; fore wings brown with basal fourth including clavus pale brown; fore femora yellow, mid and hind femora yellow with anterior margin shaded, all tibiae and tarsi yellow; prominent body setae dark brown. Head ( Fig. 137 ) rounded at cheeks, sculptured within ocellar triangle. Ocellar setae III just behind fore ocellus on margin of ocellar triangle. Postocular setae I and III slightly longer than diameter of hind ocelli, II and IV minute. Antennae ( Fig.138 ) 7-segmented and slender, II without microtrichial row, III to IV slightly rounded at each side and without apical neck, IV the longest, IV to V pedicelate, VI rounded at each side of basal half. Pronotum ( Fig. 137 ) distinctly sculptured with transverse striae, with about 40 discal setae; posteroangular setae 2 pairs; posteromarginal setae 2 or 3 pairs, setae I the longest. Mesonotum sculptured with transverse anastomosing striae, except anteromedially; CPS usually present. Metascutum ( Fig. 139 ) distinctly reticulate and with small wrinkles within reticulations; median pair of setae far from anterior margin; CPS usually present. Fore wing first vein without gap in setal row. Abdominal tergites III to VIII ( Fig. 140 ) with no lines of sculpture extending to mesad of S1 setae; tergites II to VI with S1 setae minute; tergite II with 4 lateral marginal setae; tergite VIII without posteromarginal comb; tergite IX with 2 pairs of CPS; sternites without discal setae; sternite I with three microsetae anteromedially; sternite VII with S1 setae much far from posterior margin; pleurotergites without discal setae and ciliate microtrichia.

Male macroptera. Body colour similar to female. Antennal segment VI with about 20 setae; abdominal tergite IX ( Fig. 141 ) with S1 setae at or slightly anterior to level of S2 setae and slightly longer than S2 setae, their bases equidistant; sternites III to VII ( Fig. 142 ) each with a large transverse pore plate.

Specimens examined. TAIWAN: Chiai-hsien , 2 females ( TUA) . INDONESIA: Bali Is. , 1 female ( TUA). SOUTH CELEBES: Malino , 1 female ( TUA) . THAILAND: Phuket Is. , 1 male ( TUA) .

Distribution. Japan (Ryukyus), widespread in the Oriental Region to northern Australia.

Biology. This species is associated with the flowers of Lantana , Mallotus and Beaumontia ( Palmer, 1992: 23.).

Comments. This species was described from Sumatra and T. addendus from Taiwan is now considered a synonym, but there is no record of either of these having been found in Okinawa. However, Jacot-Guillarmod (1975) and Palmer (1992) included Japan, Okinawa in their distribution lists, although we have not seen any specimens from Japan.
