Masumoto, Masami, Ng, Y. F. & Okajima, Shûji, 2013, A new genus of Thripinae (Thysanoptera, Thripidae) collected from Pandanus in Japan, Malaysia and Australia, with three new species, Zootaxa 3709 (6), pp. 543-554 : 545-547

Pandanothrips hallingi sp. n.

( Figs 1 –12)

Female macroptera ( Fig. 1 ). Distended body length 1.2–1.4 mm. Body uniformly brown; fore wing brown with basal half pale and extreme base weakly shaded, clavus pale but shaded at extreme base; all legs yellow; antennal segments ( Fig. 4 ) I–II brown, III to basal half of VI yellow, distal half of VI–VIII weakly shaded; prominent body setae weakly shaded. Head ( Fig. 3 ) 0.7–0.8 times as long as wide, almost straight at cheeks, weakly sculptured at middle between fore ocellus and tangent of posterior margin of compound eyes, sculptured with transverse anastomosing striae behind postocular setal row, slightly rugose on pre-ocellar area. Ocellar setae II posterolateral to setae III, setae III lateral to fore ocellus and shorter than distance between hind ocelli. Antennal segment II without microtrichia, III–VI tapering to apex but without neck, IV–VI pedicelate, sensoria on III and IV reaching basal third of each succeeding segment, VI the longest. Antennal segments I–VIII ratio length/width as follows: 0.7, 1.1–1.2, 1.6–2.0, 1.8–2.0, 2.2, 3.2–3.3, 1.6–2.3, 4.0–4.7. Pronotum ( Fig. 3 ) about 0.8 times as long as wide, sculptured with transverse anastomosing striae, with 13–15 discal setae; posteroangular setae I (inner pair) 0.3–0.4 times as long as pronotal median length and much longer than setae II (outer pair). Mesonotum ( Fig. 5 ) sculptured with slightly narrowly spaced anastomosing striae; anteromedian CPS absent. Metascutum reticulate medially; median pair of setae behind anterior margin, 0.2–0.3 times as long as metascutal median length; CPS absent. Prosternal basantra without setae. Fore wing costal vein with 17–22 setae, first vein without long gap in setal row, with 11–14 setae, second vein with 8–12 setae; clavus usually four veinal setae. Abdominal tergites (Fig. 7) smooth medially, a few lines of sculpture across the tergites in front of median setae, laterally with sculpture not reaching to median CPS on III–VI; median pair of setae (S1) subequal to or slightly longer than their intervals on II–VI, situated between median CPS on II–VI or VII; tergite II ( Fig. 6 ) with three lateral marginal setae, setae II (S2) close to lateral margin and vestigial; tergite VI–VIII with S4 setae reduced to small; tergite VIII (Fig. 8) with posteromarginal comb at each side; tergite IX with both anterior and posterior pair of CPS; sternites without discal setae.

Pronotum median length 138, width 178; posteroangular setae I 42 –50, setae II 34 –38. Metascutal median length 70, median setae 15. Fore wing length 570, width at middle 45. Ovipositor length 230. Antennal segments I–VIII length (width) as follows: 20 (29), 33 (28), 40 (20), 36 (20), 35 (16), 53 (16), 11 (5), 15 (4). Sensoria length on antennal segments III and VI 23 and 31.

Male microptera ( Fig. 2 ). Distended body length about 0.9 mm. Body colour similar to female but antennal segments VI–VIII much paler. Metascutal median setae situated medially (Fig. 10). Abdominal tergites (Fig. 11) with S1 and S2 setae near posterior margins; tergites IV–VIII with small scallops along posterior margins and no microtrichia; sternites III–VI each with oblong pore plates (Fig. 12), pore plates 20–23 microns width.

Measurements of paratype male. Distended body length 880. Head length 93, width across cheeks 128; compound eye dorsal length 60, width 38. Ocellar setae III length 34–35, interval 35. Pronotum median length 100, width 150; posteroangular setae I 40 –41, setae II 40 –44. Metascutal median length 53, median setae 21–24. Fore wing length 140, width at middle 40. Antennal segments I–VIII length (width) as follows: 20 (28), 25 (26), 30 (20), 28 (18), 30 (15), 44 (15), 6 (6), 15 (5). Sensoria length on antennal segments III and VI 10 and 13.
