Xylaplothrips micans Ananthakrishnan & Jagadish, 1971: 265–267 View in CoL .

This bicolored species was described from India based on three females and three males. The original description refers only to the macropterous form, but the type series contains at least one ‘apparently apterous’ paratype female ( Pitkin, 1976). According to the original description and the text figures as well as the diagnostic description by Pitkin, it has antennal segments III and IV with two (1+1) and four (2+2 +1) sense cones respectively, the maxillary stylets long and close together, the anteromarginal pronotal setae reduced, the fore tarsal tooth directed forwardls, and the terminal tube setae long, 1.67–1.75 times as long as head. Based on these features, micans View in CoL is here transferred to the genus Karnyothrips View in CoL .

Eight macropterous females collected from Bali Is., Indonesia, listed below are now identified as this species. Especially, their bicolored body color is characteristic, but is very similar to K. flavescens sp. n. described above from Vietnam. However, flavescens has only two (1+1 +1) major sense cones on antennal segment IV. Moreover, there are some small differences from the original description that require further observation. In addition, there is one macropterous female collected from the Philippines listed in the doubtful-specimens that may represent this species, but has the mid femora weakly shaded with brown. Furthermore, there is a possibility that this female has three (1+2) sense cones on antennal segment III, but these sense cones are too small and very difficult to confirm.

The full description of this species is given below based on specimens from Bali, because the original description is insufficient for the present study.

Female (macroptera). Distended body length: 1.6–2.2mm. Bicolored species. Largely yellow, but anterior portion of head, mesothorax, lateral portion of abdominal segment I, anterior half of abdominal segment II and tube brown, tube with base yellowish; head often largely brownish ( Fig. 141 View FIGURES 140–145 ); the rest of body largely yellow, but abdominal segments III–VIII each with a median brown marking along antecostal suture. Legs yellow. Antennal segment I pale brown, segments IV–VIII pale brown to brown, gradually darkened distally, segment IV with extreme base yellowish, segments II and III yellow, but segment III scarcely shaded distally. Major body setae pale. Head about 1.5 times as long as wide ( Figs 140 & 141 View FIGURES 140–145 ), widest across cheeks just behind eyes, dorsal surface almost smooth. Cheeks very weakly rounded, weakly serrate. Postocular setae shorter than eyes, expanded at apex, 98µm apart from each other, 10–15µm apart from eyes. Eyes a little shorter than 0.4 times as long as head. Ocelli well developed; posterior pair in contact with eyes, 17µm apart from each other. Antennae 1.64 times as long as head; segment VIII distinctly constricted basally ( Fig. 144 View FIGURES 140–145 ), narrowly fused to segment VII, about 0.7 times as long as VII; segment III longer than segment VII; segments III and IV subequal in length ( Fig. 145 View FIGURES 140–145 ); segments III and IV with two (1+1) and four (2+2 +1) sense cones respectively. Maxillary stylets reaching eyes, close together medially, their distance about 1/6 of head width; maxillary bridge weak. Pronotum about 0.6 times as long as head ( Fig. 141 View FIGURES 140–145 ), about 1.4 times as wide as long, almost smooth; four pairs of prominent setae expanded; pa a little longer than aa, aa and ml subequal, epim the longest, longer than postoculars. Notopleural sutures complete. Basantra wider than long; mesopresternum divided into two lateral small triangle plates; prospinasternum large, 45µm wide ( Fig. 142 View FIGURES 140–145 ). Metanotum weakly sculptured medially with longitudinal striae or reticulation; median pair of setae weak, short and acute, 20–26µm in length, 31µm apart from each other, 55µm apart from anterior margin. Fore wing with 6 duplicated cilia; three sub-basal setae expanded. Pelta trapezoid ( Fig. 143 View FIGURES 140–145 ), with irregular lateral margins, sculptured weakly, almost as long as wide. Tergite IX S1 setae expanded, shorter than tube, S2 sharply pointed, almost as long as tube, or a little longer. Tube 0.53 times as long as head, about 2.0 times as long as wide. Terminal setae about 2.0 times as long as tube.

Head length 207, from anterior margin of eyes 195, width across eyes 140, maximum width across cheeks 140, minimum width across base 115; eyes length 80; diameter of posterior ocelli 13–18; postocular setae 40–43. Maxillary bridge width 38. Antenna total length 340, segments III–VIII length (width) as follows: 48 (27), 49 (27), 42 (23), 40 (21), 42 (20), 29 (12). Pronotum length 130, width 180. Setae on prothorax: aa 35–40, ml 40–43, pa 42–48, epim 65–70. Fore wing length 760; sub-basal setae S1 43, S2 50, S3 53. Pelta length 85, width 85. Tergite IX setae: S1 80, S2 113.
