Taeniothrips damansarae sp. n.

Female macroptera. Body brown, legs mainly yellow with posterior femora lightly shaded; major setae all light brown; fore wings uniformly dark, including clavus; antennal segments I–II brown, III largely yellow but distinctly shaded medially, IV–VIII light brown with IV darkest. Head slightly wider than long, cheeks strongly rounded but constricted behind eyes; ocellar setae pair III arising within the triangle, on tangent joining anterior margins of posterior ocelli, apices of these setae blunt and bearing 2 or 3 microtrichia ( Figs 8–9 ); postocular setae small ( Fig. 3 ). Antennal segment III with apex constricted, forked sensorium extending beyond basal third of IV; segment IV with apex elongate and constricted, sensorium extending to mid-point of V; VI with 2 long and one short sensoria, several microtrichia present on basal third ( Fig. 19 ). Pronotum with bold transverse lines and about 25 discal setae; posteroangular setae with apices blunt, sometimes with a terminal microtrichium ( Fig. 3 ); posterior margin with 2 pairs of setae. Fore tarsal apical bladder at inner apex with minute claw-like process (much smaller than in inconsequens ). Mesonotal anterior campaniform sensilla absent. Metanotum transversely striate on anterior half, weakly sculptured on posterior half; campaniform sensilla on anterior half; median pair of setae at anterior margin, closer to lateral pair than to each other ( Fig. 3 ). Mesofurca with spinula, metafurca without spinula; meso and metasterna each with 40–50 fine setae. Fore wing second vein with about 11 setae; first vein with 2 setae near apex, 1 medially, about 9 setae on basal half; clavus with 5 veinal and 1 discal setae. Tergites I–VIII with no sculpture medially; VIII with long posteromarginal comb, and ctenidium-like group of irregular microtrichia anterior to both spiracles ( Fig. 14 ); X much shorter than IX. Sternites with weak transverse reticulation, VII with setae S1 and S2 arising far ahead of posterior margin.

Measurements (holotype female in microns). Body length 1600. Head, length 150; width across cheeks 175; ocellar setae—II 30, III 65. Pronotum, length 125; width 225; posteroangular setae—inner 90, outer 75. Fore wing, length 840. Tergite IX, median dorsal setae 75; setal pair S1 150. Antennal segments III–VIII length 70, 80, 55, 80, 15, 15.

Male macroptera. Similar to female, but smaller; sternites III–VII with transverse pore plate; tergite IX setae S1 ( Fig. 13 ) varying from 0.5–0.8 as long as setae S2.

Measurements (paratype male in microns). Body length 1200. Head, length 125; ocellar setae III 55. Pronotum, length 110; posteroangular setae—inner 80, outer 65. Fore wing, length 700. Tergite IX setae S1 21; S2 55. Sternal pore plate width, on V 65, on VII 50. Antennal segments III–VIII length 55, 70, 50, 85, 10, 15.

Material studied. Holotype female, Malaysia, Selangor, Hutan Simpan (Forest Reserve), Kota Damansara, in flower of Curculigo latifolia ( Liliaceae — Hypoxidaceae ), 18.iv.2011 (A. R.Khadijah), in BMNH.

Paratypes: 4 females 2 males collected with holotype, in MZUM and ANIC .

Non-paratypes: Malaysia, Perak, Taiping , 1 female, 2 males from Phaeomeria speciosa (Zingiberaceae) , 13.iii.2007 (Mark Hoddle 36), in ANIC .

Comments. This species is distinguished from nomoceras by the remarkable apices of the ocellar setae, and the blunt apices of the pronotal major setae. The apices of these setae are consistent in their form throughout all of the specimens listed above, and at present are unique amongst Thripidae . The three specimens excluded from the type series are badly damaged, but the structure of the apices of the ocellar setae is readily visible.
