Trichromothrips bruncurrum Reyes, 1994: 299 . Syn.n.

The genus Neocorynothrips comprises a single species, and was re-diagnosed and included by Bhatti (2000) in a key to the Trichromothrips group. Bhatti transferred bruncurrum Reyes to Neocorynothrips , and in the absence of the type specimens indicated two possible differences from asiaticus , based on Reyes’s original description. Two of the five original males of bruncurrum , including the holotype, have now been compared to a series of both sexes of asiaticus from Malaysia identified from the details given by Bhatti (2000). No reason could be found for considering these specimens as representing different species. Contrary to the original description of bruncurrum , antennal segment VI of the holotype is not “grayish brown” but is merely lightly shaded in less than the apical half. Moreover, the fore wing is 750 microns long with the basal hyaline area 250 microns long.

Female macroptera. Body brown. Legs shaded; fore wings pale on clavus and basal third, weakly shaded distally; antennal segments I–II brown, III–VIII yellow, VI sometimes with light shading apically. Head projecting in front of eyes and slightly wider than long, cheeks strongly constricted behind eyes, with 6–7 pairs of setae between compound eyes ventrally ( Fig. 10 ); ocellar setae pair I wide apart in front of pair II, pair III arising between posterior ocelli ( Fig. 9 ); postocular setae slender, subequal, in a single row. Antennae 8-segmented, segments I–II as wide as long, III–VI at least 2.5 times as long as wide; segment I with two dorsal apical median setae, III–IV each with forked sense cone. Pronotum with strong transverse lines and about 16 discal setae; posteroangular setae with one pair of major setae ( Fig. 9 ); posterior margin with 2 pairs of setae, first pair always longer. Mesonotal anterior campaniform sensilla absent, median setae arising at posterior margin. Metanotum transversely striate-reticulate medially, longitudinally reticulate laterally; campaniform sensilla absent; median pair of setae behind anterior margin ( Fig. 11 ). Meso and metafurca without spinula; meso and metasterna each with 15–20 fine setae. Fore wing second vein with about 14 setae; first vein with two groups of setae on basal half (3–4 and 4–5), with 2 setae near apex; clavus with 4 veinal and 1 discal setae. Tergites I–VIII with sculpture medially anterior and laterally; VIII without posteromarginal comb, and without paired ctenidia or lateral microtrichia; X much shorter than IX without longitudinal split. Sternites with weak transverse reticulation, no discal setae, VII with setae arising close to margin.

Male macroptera. Body paler than female. Tergite IX posterior margin with horn-like paired drepanae extending almost as long segment X; sternites III–VIII each with at least 50 small pore plates; sternal posteromarginal setae arise close to margin.
