( Figs 10 View FIGURES 6–19 , 45–52 View FIGURES 45–52 )
Female (macroptera). Distended body length: 2.05–2.45mm. Body bicolored ( Fig 10 View FIGURES 6–19 ). Head, thorax, abdominal segment I and legs yellow, often head very weakly shaded with brown; abdominal segments II – VIII bicolored, shaded with brown medially, yellow marginally, brown area darkened and enlarged in posterior segments, segment IX largely yellow, scarcely shaded with brown; tube brown, with basal one-fifth yellow. Antennae largely yellow, segments VII – VIII very slightly shaded. Fore wings and major body setae pale. Head much longer than wide ( Fig. 45 View FIGURES 45–52 ), 1.43 times as long as wide in holotype; dorsal surface almost smooth, sculptured laterally, but with a few transverse fine wrinkles at middle. Cheeks weakly rounded, weakly serrated. Postocular setae shorter than eyes, blunt or very weakly expanded, 137µm apart from each other, about 20µm apart from eyes in holotype. Eyes well-developed, a little longer than one-third of head length. Ocelli normal, posterior pair in contact with eyes, 38µm apart from each other in holotype. Antennae ( Fig. 52 View FIGURES 45–52 ) about 1.7 times as long as head; segment VIII rather slender, very weakly constricted at base, more than 0.9 times as long as segment VII; segment III asymmetrical, almost as long as segment IV; segments III and IV each with (1+2) and (2+2 +1) sense cones respectively. Maxillary stylets not reaching postocular setae, rather wider apart, V-shaped; maxillary bridge rather distinct, about 25µm apart from basal collar of head at middle in holotype, about half of head width. Pronotum ( Fig. 45 View FIGURES 45–52 ) well-developed, 0.83 times as long as head, 1.26 times as wide as long in holotype, almost smooth; four pairs of major prothoracic setae developed; aa and ml blunt or very weakly expanded, ml a little longer than aa; pa and epim weakly expanded, longer than postocular setae. Prosternal basantra and ferna well-developed ( Fig. 46 View FIGURES 45–52 ). Prospinasternum rather small, longer than wide, 25µm wide in holotype. Mesopresternum almost complete. Mesonotal lateral setae well-developed, weakly expanded. Metanotum distinctly sculptured with polygonal reticulation ( Fig. 47 View FIGURES 45–52 ), with no small setae before median pair of setae; median pair of setae short and acute, 55µm apart from each other, 75–78µm apart from anterior margin of metanotum in holotype. Fore femora enlarged ( Fig. 50 View FIGURES 45–52 ), sub-basal inner tubercle distinct, with two rows of small but distinct tubercles at inner margin before sub-basal tubercle; fore tibial inner apical scale distinct ( Fig. 49 View FIGURES 45–52 ). Fore wing with 5–7 duplicated cilia, with 7 cilia in holotype; sub-basal setae S1 and S2 weakly expanded, S2 longer than S1, S3 much longer than S2, blunt or very weakly expanded. Pelta trapezoid ( Fig. 48 View FIGURES 45–52 ), 1.24 times as wide as long in holotype. Tergites II – VIII S1 and S2 setae weakly expanded, but S2 on tergite II short and pointed. Tergite IX S1 and S2 setae blunt or very weakly expanded, shorter than tube, S2 longer than S1; intermediate setae short, much shorter than half of S1. Tube ( Fig. 51 View FIGURES 45–52 ) a little longer than 0.6 times as long as head, 0.63 times in holotype, a little longer than 2.0 times as long as wide, 2.25 times in holotype; terminal setae about 1.5 times as long as tube .
Measurements ( holotype female in µm). Body length 2440 (distended). Head length 258, from anterior margin of eyes 235, width across eyes 179, maximum width across cheeks 180, minimum width across base 151; eyes length 93; diameter of posterior ocelli 18–21; postocular setae 65. Maxillary bridge width 89. Antenna total length 440, segments III–VIII length (width) as follows: 67 (32), 68 (33), 55 (27), 52 (23), 44 (20), 42 (13). Pronotum length 215, width 270. Setae on prothorax: aa?35, ml about 50, pa 81, epim 80–84. Fore wing length 980. Sub-basal wing setae: S1 50, S2 65, S3 104. Pelta length 95, width 118. Tergite IX setae: S1 110–120, S2 125. Tube length 162, maximum width 72; terminal setae 245.
Male (macroptera). Distended body length: 2.0– 2.1mm. Very similar to macropterous female in structure. Abdomen largely brownish, segments VI–IX almost entirely brown; tube entirely dark brown. Head a little longer than 1.45 times as long as wide; antenna shorter than 1.7 times as long as head; pronotum about 1.7 times as long as head, about 1.3 times as long as wide; tergite IX S2 setae about half of S1, or a little longer; tube slightly shorter than 0.6 times as long as head; terminal tube setae about 1.6 times as long as tube.
Measurements ( paratype male in µm). Body length about 2000 (distended). Head length 240, from anterior margin of eyes 220, width across eyes 158, maximum width across cheeks 163, minimum width across base 134; eyes length 70; diameter of posterior ocelli 16–21; postocular setae 65–70. Maxillary bridge width 78. Antenna total length 390, segments III–VIII length as follows: 59, 57, 50, 47, 42, 39. Pronotum length 167, width 218. Setae on prothorax: aa?30, ml?35, pa 75–78, epim 70. Fore wing length 810. Sub-basal wing setae: S1 47 –48, S2 53 –55, S3 100–105. Pelta length 77, width 100. Tergite IX setae: S1 102–105, S2 55. Tube length 137, maximum width 65; terminal setae 220.
Type material. Holotype: macropterous female, Indonesia, Java, Malang, Sundeng, Sawo Sajar , 450m alt., on bamboo, 24.viii.2005, SO . Paratypes: Indonesia, Java, 2 females and 2 males, collected together with holotype .
Comments. This species is described from Java, Indonesia, based on three females and two males taken from bamboo, and probably belongs in the coimbatorensis group. It is somewhat similar to A. bambusicola sp. nov. described above from Thailand, A. coimbatorensis from India and A. huanglianensis from China also collected from bamboo in having short and V-shaped maxillary stylets and a well-developed mesopresternum that is nearly complete. However, although bambusicola , coimbatorensis and huanglianensis have uniformly brown bodies, javae has the body bicolored and largely yellowish. A. collaris which was collected from tobacco leaf in Sumatra, Indonesia, also has a bicolored body and its color pattern is somewhat similar to this species according to the original description ( Karny 1925). However, javae can be distinguished from collaris by the followings: head entirely yellow (brownish yellow with dark sides in collaris ); antennal segments VII and VIII yellow, weakly shaded with brown (dark brown in collaris ); pterothorax yellow (grayish brown in collaris ).
