Redescription. Body (Fig. 1A) almost entirely shiny to subshiny yellow brown except for dark brown ocellar tubercle and abdominal pattern; setulae and setae mostly dark brown; wing length 5.4–6.2 mm; thorax length 2.2– 2.5 mm. Head (Fig. 2A) with frons-head ratio 0.29–0.32, eye ratio 0.76–0.79, gena-eye ratio 0.09–0.11, aristaantenna ratio 1.7–1.8; medial vertical seta 0.6–0.8x longest diameter of eye; lateral vertical seta 0.6–0.7x as long as medial vertical seta; postocellar seta 0.3–0.4x as long as medial vertical seta; paravertical seta slightly shorter than postocellar seta; ocellar seta 1.5–2.0x as long as ocellar tubercle; first flagellomere 2.3–2.7x pedicel length; parafacial 0.2–0.3x as wide as first flagellomere; postgena moderately swollen with relatively long dark brown (upper area) to yellow brown (lower area) setulae; postocular setae extended 0.6–0.8x distance from upper eye margin to lower eye margin. Thorax with dorsocentral seta about half distance from level of postsutural supra-alar seta to intra-alar seta; scutellum with basal scutellar seta 2.0–2.2x as long as scutellum and apical seta 1.8–2.0x as long as scutellum. Legs entirely yellow brown with dark brown setae and setulae. Wing (Figs. 3A, B) hyaline with yellow brown to dark brown pattern; cell dm with brown band approximately between apical 2/5–1/5; wing-thorax ratio 2.6–3.0, vein R4+5 ratio 1.4–1.5, vein M ratio 0.31–0.38, subcosta-costa ratio 0.56–0.67; R4+5 dorsally with 10–11 tiny setulae between node and R-M, no setula apical to R-M.
Male abdomen yellow brown in ground color with dark brown setae and setulae; T3 sometimes with tiny posterolateral spots; T4-5 mostly dark brown with narrow yellow brown area medially (Figs. 3 E–F); epandrium (Fig. 4A) yellow brown with tiny setulae and long dark brown setae; lateral surstylus slightly longer than height of epandrium, yellow brown with more or less pointed apex in profile; posterior surstylar lobe reduced and anterior surstylar lobe expanded and bent inward; proctiger pale yellow with brown to dark brown setae; dorsal sclerite of glans extensively with internal sculpture pattern of elongated cells, these pattern lacks mid-dorsally in the holotype (Fig. 5A); vesica of glans ventrally with 9 tiny spines.
Female abdomen yellow brown ground color, dorsally with dark brown lateral spots as in males (Fig. 3 G); oviscape (Figs. 3 G, 6A) entirely shiny dark brown, about as long as wide, also about as long as two preceeding preabdominal segments, with pair of short ventral marginal setae; eversible membrane with taeniae about half as long as total length of membrane, ventrally on basal half with spinules moderately well differentiated (Fig. 6A); aculeus (Fig. 6 C) broad, about twice as long as wide, basally constricted, more or less parallel-sided with apical half tapered with serration; 2 brown spermathecae ovatus in outline with transverse spinular papillae (Fig. 6 E). Egg (Fig. 6 G) ovatus in outline with tiny knoblike micropylar end.
Type material. Holotype male (HNHM) from Taiwan with four labels with the following information: “ Formosa Sauter,” “Tapani, 1911. III,” “ Acidiella longipennis Typus det. Hendel,” and “ typus.” Left wing missing, right wing partially demaged (Fig. 3A), and abdomen dissected and kept in a genitalia vial.
Additional material examined. MYANMAR: Kambaiti, 2000 m, 12.IV.1934, R. Malaise; 5.V.1934, 2ɗ 1Ψ; same, 1.V.1934, 1ɗ; same, 15.V.1934, 1ɗ. All the Myanmar specimens are deposited in NRS.
Distribution. Taiwan and Myanmar. The distribution records from China, Philippines, and Indonesia (Norrbom et al., 1999) should require confirmation because the past concept of the species encompasses all three species of the A. longipennis species group.
