description: Neandrothrips spinipes sp. nov.
(Figs 242–243, 275–281)
Female (macroptera). Distended body length: about 1.5mm. Body bicolored pale brown and yellow (Fig. 242). Head, thorax and tube pale brown; abdominal segments I–VII yellow, segments III–VII each with a median pale brown marking along antecostal suture; segments VIII and IX scarcely shaded with pale brown, segment VIII paler anteriorly. Fore and mid femora largely pale brown, fore femora with anterior half paler, hind femora scarcely tinged with pale brown; all tibiae and tarsi clear yellow. Antennal segments I, II and VI–VIII pale brown; segment III yellow; segments IV and VI yellow to pale brown, gradually darkened distally. Fore wing and major setae pale. Head (Fig. 275) longer than wide, 1.24 times as long as wide, widest across cheeks just behind eyes; dorsal surface almost smooth, very weakly sculptured with transverse striae. Cheeks weakly rounded, weakly serrated. Eyes 0.36 times as long as head. Ocelli normal; posterior pair scarcely separated from eyes, 21µm apart from each other. Postocular setae much shorter than eyes, expanded; about 100µm apart from each other, about 10µm apart from eyes. Antennae (Fig. 280) 1.76 times as long as head; segment VIII very weakly constricted at base, narrowly joined to VII, 0.8 times as long as VII; segment III a little shorter than segment IV, longer than segment VII; segments III and IV with two (1+1) and four (2+2 +1) sense cones respectively. Maxillary stylets scarcely reaching the middle of head capsule, wider apart, almost V-shaped; maxillary bridge weak, about half of head width. Pronotum (Fig. 275) 0.55 times as long as head, 1.78 times as wide as long; almost smooth, median apodeme weak; five pairs of prothoracic setae expanded. Prospinasternum (Fig. 277) circular, 25µm wide; mesopresternum complete. Mesonotal lateral setae, 17–18µm long. Metanotum very weakly sculptured with reticulation; median pair of setae pointed, 22–24µm, their distance a little narrower than the distance between that seta and anterior margin of metanotum, 38µm apart from each other, about 40µm apart from anterior margin. Fore tarsus with a small tooth. Fore wing with 5 duplicated cilia; three sub-basal setae expanded, S3 the longest. Pelta very weak, trapezoid, 1.58 times as wide as long. Tergites III–VIII S2 setae: III–VI expanded, VII sharply pointed, VIII bluntly pointed. Tergite IX S1 setae blunt, shorter than tube, S2 sharply pointed, longer than S1, a little shorter than tube; intermediate setae longer than two-thirds of S1. Tube about 0.56 times as long as head, about 2.1 times as long as wide; terminal setae about 1.5 times as long as tube.
Measurements (holotype female in µm). Body length 1470 (distended). Head length 170, from anterior margin of eyes 155, width across eyes 132, maximum width across cheeks 137, minimum width across base 110; eyes length 61; diameter of posterior ocelli 12–15; postocular setae 25. Maxillary bridge width 70. Antenna total length 300, segments III–VIII length (width) as follows: 38 (23), 42 (28), 37 (23), 37 (20), 35 (18), 28 (10). Pronotum length 93, width 166. Setae on prothorax: am about 20, aa about 20, ml?25, pa 28–30, epim 33–35. Fore wing length 560. Sub-basal wing setae: S1 28 –30, S2 25 –27, S3 52 –57. Pelta length 53, width 84. Tergite IX setae: S1 65–67, S2 80–90. Tube length 95, maximum width 45; terminal setae 140.
Male (macroptera). Distended body length: 1.3mm. Very similar to macropterous female. Color somewhat darker, bicolored brown and yellow (Fig. 243); head, thorax, abdominal segments VIII–IX and tube brown; all femora brown, fore tibia scarcely tinged with pale brown; intermediate abdominal segments without median markings. Intermediate antennal segments somewhat slender; fore femur (Fig. 279) with an indistinct median hamp on inner-ventral surface; fore tibia (Fig. 278) with several well-developed inner seta-bearing tubercles.
Measurements (paratype male in µm). Body length about 1300 (distended). Head length 155, from anterior margin of eyes 143, width across eyes 128, maximum width across cheeks 132, minimum width across base 101; eyes length 53; diameter of posterior ocelli 12–13; postocular setae about 30. Maxillary bridge width 60. Antenna total length 310, segments III–VIII length (width) as follows: 43 (21), 43 (23), 43 (20), 39 (18), 38 (17), 30 (10). Pronotum length 86, width 158. Setae on prothorax: am 17–18, aa 20, ml?, pa 27–26, epim 33. Fore wing length 550. Sub-basal wing setae: S1 30, S2 32 –33, S3 60 –64. Pelta length 48, width 70. Tergite IX setae: S1 60, S2 25 –26. Tube length 82, maximum width 42; terminal setae 135.
Type material. Holotype: macropterous female, Indonesia, Bali, Tabanan, Muncak Sari, Pura Luhur, 755m alt., habitat uncertain, 3.ix.2006, SO. Paratypes: Indonesia, Bali, 1 male, data very similar to holotype, but 2.ix.2006; 1 male, Tabanan, Pakaranean, 1067m alt., 1.ix.2006, SO.
Comments. This species is described from Bali, Indonesia based on one female and two males, but the habitat is uncertain. It may be included in the pictipes -group and is very similar in appearance to N. rangi sp. nov. from Phuket Is., southern Thailand, described above. These two species have the body bicolored brown and yellow, antennal segments III and IV with two and four sense cones respectively. However, spinipes can be distinguished from rangi by the following features: head about 1.2 times as long as wide; antennal segment IV with an additional small sense cone, (2+2 +1); maxillary bridge wider, about half of head width; metanotal median setae closer together and far from anterior margin of metanotum; pelta very weak; male fore femora with indistinct median hump on inner-ventral surface; male fore tibia with four or five seta-bearing well developed tubercles.
