Cephalic setae, marginal setae on abdominal tergite I and setae on tergite VIII 0.68 times, 0.61 times and 1.01 times as long as widest diameter of antennal segment III, respectively. Front straight. Eyes 3-faceted. Antennae 3- or 4-segmented (Fig. 1); 0.14 times as long as body. Length in proportion of segments I–III: 35 : 26 : 100+16, respectively. Processus terminalis 0.16 times as long as base of the segment III; very thin, basal width 0.47–0.57 times as long as apical width of base of the segment III. Setae on antennae sparse. Segments I–III each with 2, 2, 0+0 setae, respectively. Processus terminalis with 4 apical setae. Primary rhinaria small, round, protuberant and placed wide apart. Rostrum short and thick, not reaching mid-coxae. Ultimate rostral segment blunt wedge-shaped, 1.43 times as long as its basal width, 0.88 times as long as second hind tarsal segment; with 2 pairs of primary setae and 1 pair of accessory setae. Legs normal. Trochanters and femora fused. Hind trochanter and femur 2.11 times as long as the base of antennal segment III, hind tibia 0.15 times as long as body. Setae on legs sparse, fine and pointed. Setae on hind tibia 0.68 times as long as its mid-diameter. First tarsal chaetotaxy: 2, 2, 2. Siphunculi absent. Cauda, anal plate and genital plate with dense spinulose imbrications. Cauda knobbed, indistinctly constricted at base, 0.74 times as long as its basal width, with 9 setae. Anal plate bilobed, each with 9 or 10 setae. Genital plate broad round, with 2 anterior setae and 11 setae along the posterior margin. Two gonapophyses each with 3 or 4 short setae. (emigrants from galls): Body oval (Fig. 9), cephalothorax black, abdomen dark reddish brown and pterostigma black in life, wings flat in repose. For morphometric data seeTable 1. Head, thorax, antennae, ultimate rostral segment, legs and genital plate brown, abdominal tergites VII–VIII with brown broad transverse bands, forewing veins and pterostigma brown, the other parts of body pale. Dorsum of head with sparse imbrications, tibiae, tarsi, venter of femora and abdominal tergites VI–VIII with dense spinulose imbrications. Spiracles oval, closed, on abdominal segments II–VI, spiracular plates brown. Dorsal setae of body short and pointed, on light brown seta-bearing sclerites. Head with 10–25 dorsal setae between antennae and 15–20 dorsal setae between eyes; pronotum with 1 pair of spinal, 1 pair of pleural and 2 pairs of marginal setae; mesonotum with 19–30 setae; abdominal tergite I with 5–8 spino-pleural and 1 pair of marginal setae; abdominal tergite II with 4–9 spino-pleural and 1 pair of marginal setae; abdominal tergite III with 6–8 spino-pleural and 1 pair of marginal setae; abdominal tergites IV–V each with 5–8 spino-pleural and 1 pair of marginal setae; abdominal tergites VI–VII each with 4–6 spino-pleural and 1 pair of marginal setae; tergite VIII with 5–8 setae. Cephalic setae, marginal setae on abdominal tergite I and spinal setae on tergite VIII 0.22–0.33 times, 0.29–0.53 times and 0.58–0.80 times as long as widest diameter of antennal segment III, respectively. Head (Fig. 10): Front protuberant. Eyes compound. Antennae 5-segmented (Figs. 2, 11), with dense spinulose imbrications on segments III–V; 0.32–0.35 times as long as body. Length in proportion of segments I–V: 15 : 12 : 100 : 45 : 19+7, respectively. Processus terminalis 0.24–0.48 times as long as base of the segment V. Setae on antennaesparse. Segments I–V each with 1–3, 2, 0, 0, 0+0 setae, respectively. Processus terminalis with 5 apical setae. Primary rhinaria small, round and ciliated. Segments III, IV and base of segment V each with 37–44, 16–21, 6–9 annular secondary rhinaria, respectively. Rostrum short, not reaching mid-coxae. Ultimate rostral segment blunt wedge-shaped (Figs. 3, 12), 1.09–1.55 times as long as its basal width, 0.61–0.71 times as long as second hind tarsal segment; with 2 pairs of primary setae and 1 pair of accessory setae.
