description: Euidothrips antennatus n. sp.
(Figs.1 A & 2A–F)
Female macroptera. Distended body length 1.1–1.3 mm. Body bicoloured (Fig. 1 A). Head yellow but dark brown between compound eyes, border of dark and yellow areas distinct; antennal segments I–V yellow, VI–VIII brown with basal third of VI yellowish; pronotum and abdomen uniformly yellow; pterothorax yellow with pleural areas dark brown, lateral areas of meso- and metanota shaded; all legs yellow; fore wing yellow with extreme base brown, clavus shaded; major setae yellow.
Head (Fig. 2 A) 1.0 times as long as wide, polygonally reticulate just behind compound eyes at each side. Antennal segment III bit strongly curved to outside, IV with weak apical neck, V–VI not pedicelate (Fig. 2 B, C). Ratio length/width of antennal segments I to VIII as follows:0.6–0.7,0.9, 2.7–2.9, 3.1–3.9, 2.7–3.0, 4.2, 3.5–4.0, 7.3–10.5.
Pronotum (Fig. 2 A) 0.7 times as long as wide, almost uniformly reticulate, reticulation longitudinal at middle, with 34–36 discal setae medially. Metascutum with CPS. Fore wing costal vein with21–23 setae, posterior fringe cilia slightly undulating. Tarsi 2-segmented.
Abdominal tergites (Fig. 2 E, D) with median reticulations not longitudinal; tergites I–VI with submedian areas smooth and no posteromarginal fringe behind median reticulations on I–V; tergites III–VII with about 15 small setae on lateral reticulate areas; tergite VIII with spiracles large, about two-thirds of lateral tergal length; tergite IX with S1 setae not exceeding middle of tergite X; sternites (Fig. 2 F) with 7–20 discal setae arranged in irregular lines, smooth posteromedially, reticulations almost same size medially and laterally; sternites III–VII each with three pairs of setae at posterior margin, but S1 and S2 setae in front of posterior margin on VII. Ovipositor 1.5–1.7 times as long as median length of pronotum.
Measurements of holotype female in microns. Total body length 1310; head length 150 (length including anterior prolongation 165), width across cheeks 153; compound eye dorsal length 75, width 40; pronotal median length 124, width 175; metascutal median length 68; fore wing length 590, width at base 70, width at middle 20; abdominal tergite IX median length 95, S1 setae length 25; tergite X median length 50; ovipositor length 180. Antennal segments I–VIII length (width) as follows: 20 (30), 30 (35), 58 (20), 73 (19), 45 (15), 58 (14), 20 (5), 28 (4).
Male. Unknown.
Type series. Indonesia, Bali. Holotype female, Buleleng, Desa Melanting [S08°10’30”, E114°40’47” ca. 135m alt.], host unknown, 31.viii.2005, S. Okajima.
Paratypes: all host unknown and collected S. Okajima; 2 females with holotype; 26 females, Buleleng, Desa Melanting [S08°10’57”, E114°40’56” ca. 150m alt.], 16.viii.2006; 16 females, Buleleng, Desa Melanting [S08°10’57”, E114°40’56” ca. 150m alt.], 17.viii.2006; 24 females, Buleleng, Beatung [S08°10’21”, E114°40’58” ca. 130m alt.], 15.viii.2006; 16 females, Buleleng, Beatung [S08°10’21”, E114°40’58” ca. 130m alt.], 16.viii.2006; 16 females, Buleleng, Beatung [S08°10’21”, E114°40’58” ca. 130m alt.], 17.viii.2006.
Comments. This new species is similar to E. borneoensis in body colour and abdominal sculpture, and in having sterna discal setae and a strongly curved antennal segment III. They are distinguishable by the key above.
