( Figs 8 View FIGURES 6–19 , 28–36 View FIGURES 28–36 )

Female (macroptera). Distended body length: 2.0– 2.3mm. Body brown to dark brown ( Fig. 8 View FIGURES 6–19 ). Femora brown, fore femora with apices slightly paler; fore tibiae yellow, mid and hind tibiae pale brown (cf. Fig. 35 View FIGURES 28–36 ), at least not clear yellow, with paler apices; tarsi yellow. Antennal segments I– II brown, but somewhat paler than head, segment II slightly paler antero-externally; segments III – V yellow; segment VI shaded with brown at anterior half, yellowish at basal half; segments VII – VIII brown. Fore wings very slightly shaded. Major body setae pale. Head much longer than wide ( Fig. 28 View FIGURES 28–36 ), 1.37 times as long as wide in holotype; dorsal surface almost smooth, sculptured laterally, but with a few transverse fine wrinkles at middle. Cheeks sub-parallel, very weakly rounded, weakly serrated. Postocular setae shorter than eyes, weakly expanded, 120µm apart from each other, about 15µm apart from eyes in holotype. Eyes about one-third as long as head, or a little longer, 0.35 times as long as head in holotype. Ocelli relatively small; posterior pair slightly separated from eyes, about 30µm apart from each other in holotype. Antennae ( Fig. 36 View FIGURES 28–36 ) about 1.7 times as long as head; segment VIII very weakly constricted at base, a little longer than 0.8 times as long as segment VII; segment III a little shorter than segment IV; segments III and IV each with (1+2) and (2+2) sense cones respectively, these sense cones are short and slender, very difficult to observe. Maxillary stylets retracted to postocular setae, rather close together at middle, a little wider than one-third of head width; maxillary bridge rather distinct, situated at about 40µm from basal collar of head. Pronotum 0.62 times as long as head, 1.57 times as wide as long in holotype, almost smooth; four pairs of major prothoracic setae well-developed, expanded; pa almost as long as postocular setae, or a little longer; epim the longest. Prosternal basantra and ferna well-developed ( Fig. 29 View FIGURES 28–36 ). Prospinasternum usually longer than wide, 25µm wide in holotype. Mesopresternum narrowly boat-shaped ( Fig. 30 View FIGURES 28–36 ) or divided ( Fig. 29 View FIGURES 28–36 ). Mesonotal lateral setae well-developed, weakly expanded, 30µm long in holotype. Metanotum sculptured with polygonal reticulation ( Fig. 31 View FIGURES 28–36 ), with a pair of small setae before median pair of setae; median pair of setae relatively stout, pointed, 36–37µm in length, 39µm apart from each other, about 70µm apart from anterior margin of metanotum in holotype. Fore femora typical of the genus ( Fig. 34 View FIGURES 28–36 ), but not so enlarged, with a few small tubercles at inner margin before sub-basal tubercle; fore tibial inner apical scale slender ( Fig. 33 View FIGURES 28–36 ). Fore wing with 6–8 duplicated cilia, with 6–7 in holotype; sub-basal setae S1 and S2 expanded, S2 longer than S1, S3 much longer than S2, pointed or bluntly pointed. Pelta trapezoid or nearly triangular ( Fig. 32 View FIGURES 28–36 ), 1.16 times as wide as long in holotype. Tergites II – VIII S1 setae very weakly expanded. Tergites III – VIII S2 setae: III – V short and blunt or very weakly expanded, VI – VIII pointed or nearly pointed. Tergite IX S1 and S2 setae pointed, longer than tube, S2 longer than S1; intermediate setae short, shorter than one-third of S1. Tube shorter than 0.6 times as long as head, 0.56 times in holotype, about 1.9 times as long as wide; terminal setae about 1.5 times as long as tube, or a little longer .

Measurements ( holotype female in µm). Body length about 2200 (distended). Head length 228, from anterior margin of eyes 210, width across eyes 164, maximum width across cheeks 167, minimum width across base 143; eyes length 79; diameter of posterior ocelli 13–15; postocular setae 60–65. Maxillary bridge width 65. Antenna total length about 380, segments III–VIII length (width) as follows: 57 (30), 59 (32), 49 (28), 45 (26), 40 (22), 33 (13). Pronotum length 142, width 223. Setae on prothorax: aa 55, ml 50, pa 67–68, epim 70–80. Fore wing length about 900. Sub-basal wing setae: S1 50 –52, S2 67–70, S3 110–112. Pelta length 93, width 108. Tergite IX setae: S1 136, S2 158–160. Tube length 128, maximum width 69; terminal setae?.

Male (macroptera). Distended body length: 1.65–1.90mm. Very similar to macropterous female in color and structure. Head 1.30–1.35 times as long as wide; maxillary bridge somewhat wider, 0.43–0.46 times as wide as head; fore wing with 5–7 duplicated cilia; tergite IX S2 setae shorter than one-fourth of S1; tube longer than 0.6 times as long as head.

Measurements ( paratype male in µm). Body length about 1800 (distended). Head length 197, from anterior margin of eyes 182, width across eyes 146, maximum width across cheeks 148, minimum width across base 129; eyes length 73; diameter of posterior ocelli 12–14; postocular setae 57–60. Maxillary bridge width 66. Antenna total length 370, segments III–VIII length as follows: 54, 57, 45, 44, 40, 32. Pronotum length 118, width 210. Setae on prothorax: aa 45–47, ml about 50, pa 53–58, epim 66–68. Fore wing length 760. Sub-basal wing setae: S1 45 –46, S2 57 –58, S3 87. Pelta length 78, width 84. Tergite IX setae: S1 113–115, S2 23 –25. Tube length 127, maximum width 53; terminal setae 163.

Type material. Holotype: macropterous female, Indonesia, Sulawesi, 11km E from Malino, Kanreapia , alt. about 1500m, on grass, 2.viii.1984, SO . Paratypes: Indonesia, Sulawesi, 4 females and 6 males, collected together with holotype .

Comments. This species is described from Sulawesi, Indonesia, based on five females and six males taken from grasses, and has the mid and hind tibiae brown. Amongst previously described 12 species of the genus, only two species, A. crus and A. ramachandrai , have the mid and hind tibiae brown, at least not yellow, and the other ten species have the tibiae clear yellow. Although crus and ramachandrai have antennal segment IV with one outer small sense cone in addition to the four major sense cones, (2+2 +1), fuscipes has only four major sense cones, (2+2).
