Asianthrips sufflavus View in CoL sp. n.
( Figs 24 View FIGURES 23–28 , 131–136 View FIGURES 131–136 )
Female macroptera. Body bicolourous, largely yellow and partly shaded with brown ( Fig. 24 View FIGURES 23–28 ); ocellar area and genal areas just behind eyes, mesothrorax, lateral portions of metathorax and abdominal segment I, anterolateral portions of abdominal segment II, and tube brownish, the remaining of the body yellow; tergites III–VII each with a median pale brown marking at just behind antecostal suture. Antennal segment III yellowish, segments I and II pale brown, segments IV–VIII brown. All legs yellowish. Fore wings very weakly shaded. Body setae almost colourless. Head ( Fig. 131 View FIGURES 131–136 ) almost as long as wide; dorsal surface sculptured with transverse reticulation, but the reticles weak at anterior half. Cheeks weakly rounded, slightly narrowed towards base. Postocular setae shorter than eyes. Postocellar setae almost as long as or a little shorter than a diameter of posterior ocellus. Eyes large, 0.41–0.42 times as long as head. Antennal segments VII and VIII somewhat broadly fused, but segment VIII not constricted basally, cone-shaped ( Fig. 132 View FIGURES 131–136 ); segments VI and VII each with 5–6 setae on dorsum; segment III with three sense cones. Maxillary stylets rather short, retracted into 1/4 of head, almost V-shaped. Pronotum ( Fig. 133 View FIGURES 131–136 ) 0.67 times as long as head and 1.76 times as wide as long, median portion almost smooth, but with an irregular short and weak median longitudinal line; epim the longest, pa about 0.46–0.47 times as long as median pronotal length. Basantra weakly developed. Metanotum ( Fig. 134 View FIGURES 131–136 ) polygonally reticulated, but very weak. Prospinasternum well developed. Mesopresternum and mesoeusternum ( Fig. 135 View FIGURES 131–136 ) widely fused, with short sutures between them at both sides. Fore tarsi unarmed. Fore wings with 4–4 duplicated cilia. Tergites not small, tergites III–V much wider than pronotum. S1 and S2 setae on tergite IX weakly expanded, S1 0.68–0.73 times as long as tube, almost as long as S2. Tube ( Fig. 136 View FIGURES 131–136 ) 0.58 times as long as head. Anal setae almost as long as tube.
Measurements. Female holotype (mac.) in microns. Distended body length about 1500. Head length 147, width across cheeks 147. Compound eye dorsal length 60–62. Pronotum length 98, width 172. Fore wing length about 570. Tube length 85, width across base 47. Antenna length about 320, segments III–VIII length (width) as follows: 46 (26), 49 (26), 42 (22), 40 (20), 37 (18), 27 (13). Postocular setae about 50. Pronotal aa about 40, am 40–42, ml 42–45, pa 45–46, epim 50–52. S1 setae on tergite IX 58–62, S2 setae on tergite IX 57–58. Anal setae 85–89.
Male macroptera. Very similar in colour and structure to macropterous female, except for the followings: Body smaller, tergite V almost as wide as pronotum; fore wings with 3–5 duplicated cilia; anal setae a little shorter than tube. Fore tarsi unarmed.
Measurements. Male paratype (mac.) in microns. Distended body length 1150. Head length 131, width across cheeks 123. Compound eye dorsal length 53–55. Pronotum length 80, width 133. Fore wing length about 450. Tube length 70, width across base 38. Antenna length about 290, segments III–VIII length (width) as follows: 42 (24), 45 (24), 38 (22), 37 (19), 33 (18), 25 (12). Postocular setae 41–43. Pronotal aa?, am about 30, ml about 30, pa 33–34, epim 35–36. S1 setae on tergite IX 45, S2 setae on tergite IX 22–23. Anal setae 62–63.
Type series. Holotype female (mac.): Thailand, Phuket Is., nr. Tone Sai Waterfall , on dead leaves and branches, 14.ix.1992 (TN & SO) . Paratypes: Thailand, 2 males (mac.), collected with holotype , 1 male (mac.), data very similar to holotype, but 11.ix.1992.
Remarks. A. sufflavus is very similar to A. pallens from Taiwan, and the difference between these two is discussed under A. pallens . The chaetotaxy of the dorsum of the distal antennal segments of this species may be peculiar among the genus.
