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 : 550-553

Pandanothrips wangi sp. nov.

( Figs 23–33 )

Female macroptera ( Fig. 23 ). Distended body length 1.1mm. Body bicoloured, head and abdominal segment III–X slightly darker; fore wing pale at subbasal and extreme apical areas, clavus dark at extreme base; all legs yellow; antennal segments I–II shaded, III–V yellow, VI–VIII slightly shaded ( Fig. 27 ); prominent body setae pale brown. Head ( Fig. 25 ) 0.6 times as long as wide, slightly convex at cheeks, ocellar triangular area smooth, pre-ocellar area slightly rugose, post-ocellar area with irregular transverse striae. Ocellar setae III shorter than distance between hind ocelli. Antennal segment II without microtrichia, III–VI normal not tapering apically, sensoria on III and IV elongate and reaching near middle of each succeeding segment, VI the longest. Antennal segments I–VIII ratio length/width as follows: 0.5–0.6, 0.9–1.1, 1.7–1.9, 1.9–2.1, 2.0–2.2, 3.0–3.1, 1.1–1.3, 3.8–4.0. Pronotum ( Fig. 25 ) 0.7 times as long as wide, sculptured with transverse anastomosing striae, with about 12–16 discal setae; posteroangular setae I about 0.4 times as long as pronotum length and much longer than setae II. Mesonotum ( Fig. 28 ) sculptured with slightly narrowly spaced anastomosing striae; anteromedian CPS present (one specimen with only right CPS present); metascutum median and submedian setae subequal, about 0.3 times as long as metascutal median length; CPS absent. Prosternal basantra with a pair of setae ( Fig. 26 ). Fore wing ( Fig. 30 ) first vein with 8+2 setae, second vein with 7 setae. Abdominal tergites ( Fig. 31 ) smooth medially, tergites II–VII with lateral sculpture not reaching to median CPS, with minute microtrichia along sculpture; tergite II with three lateral marginal setae (in Holotype only with 2 pair lateral setae, pair II absent), setae II close to lateral margin; tergite VIII with posteromarginal comb complete but microtrichia small on median third; tergite IX with both anterior and posterior pair of CPS; sternites without discal setae.

Measurements of holotype female. Distended body length 1120. Head length 110, width across cheeks 150; compound eye dorsal length 60, width 42. Ocellar setae III length 29, interval 41. Pronotum median length 115, width 166; posteroangular setae I 38, setae II 24. Metascutal median length 52, median setae 16. Fore wing length 493, width at middle 41. Ovipositor length 183. Antennal segments I–VIII length (width) as follows: 15 (26), 23 (25), 33 (18), 37 (17), 32(14), 45(15), 9 (7), 13(3.3). Sensoria length on antennal segments III and VI 22 and 28.

Male hemimacroptera ( Fig. 24 ). Distended body length about 1.0 mm. Body yellow; all femora and tibiae yellow; antennal segments I–V yellow, segment VI apical half, VII and VIII slightly shaded. Pronotal posteroangular setae I much longer than setae II. Fore wing ( Fig. 29 ) subapex shaded. Abdominal tergite VIII ( Fig. 32 ) with posteromarginal comb short medially; sternites III–VII with oblong pore plates ( Fig. 33 ), 25–38 microns wide.

Measurements of paratype male. Distended body length 1000. Head length 108, width across cheeks 129; compound eye dorsal length 67, width 40. Ocellar setae III length 33, interval 34. Pronotum median length 101, width 146; posteroangular setae I 34 –35, setae II 26. Metascutal median length 48, median setae 15. Fore wing length 226, width at middle 39. Antennal segments I–VIII length (width) as follows: 10 (24), 30 (24), 31 (16), 29 (16), 27(15), 36 (15), 8 (6), 12 (3). Sensoria length on antennal segments III and VI 12 and 16.
