(Figs. 1 B, 2B, 2D & 4B)
Female macroptera. Distended body length 1.3–1.5 mm. Body indistinctly bicoloured; head pale brown, darker within ocellar triangle and in front of ocellar triangle, with basal fourth of dorsal surface pale; antennal segment I brown, II brown with distal half yellowish, III– IV yellow, V yellowish with basal third brown, VI–VIII brown; pronotum to metanotum pale, slightly shaded at mesonotum and metascutum; abdomen yellowish brown to brown, gradually darkened toward segment X, or almost uniformly brownish yellow; fore wings slightly shaded with basal fourth slightly pale, scale slightly shaded; all legs yellow; prominent body setae pale.
Head (Fig. 1 B) 0.7–0.8 times as long as wide, slightly sculptured with transverse striae on basal third of dorsal surface laterally, smooth medially; ocellar setae II much longer than III, reaching posterior margin of hind ocelli. Antennal segment VI (Fig. 2 B) the longest. Antennal segments I to VIII ratio length/width as followings: 0.8–1.0, 1.1–1.2, 2.1–2.4, 2.1–2.6, 2.0–2.7, 3.0–3.5, 1.3–1.7, 3.0–3.5.
Pronotum (Fig. 1 B) 0.6–0.7 times as long as wide, distinctly eroded at anterior margin, with 23–33 discal setae; two or three pairs of anteromarginal setae much longer than discal setae laterally, S2 setae the longest and 0.5–0.6 times as long as pronotal median length; posteroangular setae I 0.6–0.7 times as long as pronotal median length and slightly longer than setae II; posteromarginal setae three to five pairs, setae I the longest, about 1.5–2 times as long as other setae, 0.6–0.8 times as long as pronotal median length. Mesonotum (Fig. 2 D) without campaniform sensilla anteromedially. Fore wings costal vein with 22–27 setae, second vein with 13–16 setae; clavus with 4 (rarely 3) veinal setae and 1 discal setae.
Abdominal tergites II–VIII sculptured with anastomosing striae laterally and a few striae at anterior half between S2 setae; tergites V–VIII with S4 setae minute; tergite IX with SS2 setae (Fig. 4 B). Ovipositor 1.3–1.5 times as long as pronotal median length.
Measurements (holotype female in microns). Distended body length 1275. Head length 83, across cheeks 108; compound eyes dorsal length 63, width 40; ocellar setae II length 52; ocellar setae III length (interval) 28 (10). Pronotum median length (width) 95 (153); anteromarginal setae I length 48, setae II length 50; posteroangular setae I length 59, setae II length 63; posteromarginal setae I length 55. Metascutum median length 83; median setae length 25. Fore wings length 600. Ovipositor 143. Antennal segments I to VII length (width) as followings: 23 (25), 29 (25), 38 (18), 40 (18), 35 (18), 50 (15), 13 (8), 15 (5).
Male. unknown.
Type series. Holotype female, Vietnam, Lam Dong Province, Bao Loc, Dam Bri, on bamboo, 27.xii.2001, S. Okajima. Paratypes: 1 female, same place and plant as holotype, 26.xii.2001, S. Okajima. 1 female, same place, on grass, 26.xii.2001, S. Okajima. 3 females, same place and plant as holotype, 28.xii.2001, S. Okajima.
Comments. This species can be distinguished easily by the pronotum having the anterior margin strongly concave.
