Azaleothrips inflavus sp.n.

( Figs 54–57 )

Female macroptera. Body bicolorous yellow and brown. Head yellow, lateral and anterior margins brown ( Fig. 54 ). Prothorax yellow, lateral margins brown. Meso- and metathorax pale brown; posterior 2/5 of metanotum yellow ( Fig. 57 ). Pelta yellowish; abdominal segments yellow to brownish yellow, intermediate segments with both sides brown; segments VIII and IX entirely yellow to brownish yellow. Tube brown, with base yellowish. Antennal segment III yellow, very weakly shaded with brown at apical 3/5; extreme base of segment IV yellowish; the remaining segments brown. Fore femora yellowish, shaded with brown at apical 1/2; mid and hind femora brown, with bases and apices yellow; all tibiae brownish subbasally, with bases and apices yellow. Fore wing weakly shaded with brown, paler at basal 1/4 and median constriction.

Head ( Fig. 54 ) a little longer than wide; dorsal surface entirely strongly sculptured with reticles, with delicate wrinkles among reticles, without tubercles. Postocular setae longer than half the length of compound eye. Antennal segments VIII distinct from segment VII ( Fig. 55 ); segment IV a little longer than segment III, about 1.9 times as long as wide; segment III with three (1 + 2), segment IV with four (2 + 2) sensoria. Pronotum ( Fig. 56 ) generally sculptured with lines of reticulation, almost smooth or with very weak wrinkles among reticles, not tuberculate, with 22 short setae in holotype. Basantra absent. Mesonotum ( Fig. 57 ) with small dentate microtrichia or tubercles along transverse lines of sculpture, almost smooth or very weakly course among lines. Metanotum ( Fig. 57 ) longitudinally striate at anterior half, with polygonal reticulations at posterior half, with fine dots among striae, almost smooth or with very weak inner markings among reticles; anterior half usually with 4 short setae. Fore tarsus armed with a small tooth. Fore wing with 9/9 duplicated cilia in holotype. Pelta weakly reticulate, almost smooth among reticles. S1 setae of tergite IX a little longer than half the length of tube; S2 setae expanded at apex. Tube about 0.6 times as long as head. Anal setae much longer than tube.

Measurements (holotype female in microns). Distended body length 1850. Head length 200, width across cheeks 190. Pronotum length 128, width 221. Fore wing length about 700. Tube length 113, width across base 50. Antenna length about 340, segments III–VIII length (width) as follows: 50 (30), 54 (28), 47 (24), 46 (23), 36 (21), 22 (12). Postocular setae about 40. S1 setae on tergite IX 62 –63, S2 setae on tergite IX about 80. Anal setae 158.

Male. Unknown.

Paratypes: Indonesia, 34 females, collected with holotype; 5 females, Bali Is., Tabanan, Jatiluwih (Batu Lumbang Temple), on dead branches, 14.iii.2005 (SO); 1 female, Bali . Is., Tabanan, Muncak Sari, Pura Luhur, 11.viii.2006 (SO); 1 female, Java, Banyuwangi, Glemor, Tulung Rajo, Sumber Gondo, on dead branches, 27viiiI.2005 (SO); Singapore, 1 female, Macritche Res., on dead branches, 8.viii.1990 (TN & SO); Philippines, Mindanao Is., North Cotabato, Ilomavis, 2 females, on dead leaves, 26.vii.1979, 1 female, on dead branches, 27.vii.1979 (SO).

Remarks. This species belongs to the amabilis group, and is distinctive within the genus in the largely yellowish body color. Although more than 40 female specimens are examined, the male of this species remains unknown. Moreover, the distribution of this species is comparatively wide within the genus.
