Female (macroptera). Distended body length: 1.6–1.7mm. Body brown ( Fig. 245 View FIGURES 236–245 ). All femora brown; fore tibia brown, with base yellowish; mid and hind tibiae brown with bases yellowish, with extreme apices somewhat paler; tarsi yellow. Antennae brown, segment III scarcely paler than segment IV, with extreme base yellowish. Fore wing weakly shaded with brown. Major body setae pale. Head ( Fig. 290 View FIGURES 290–296 ) longer than 1.2 times as long as wide, 1.26 times in holotype; dorsal surface sculptured laterally and posteriorly with transverse striae, almost smooth at middle. Cheeks rounded, constricted at base, weakly serrated. Eyes well developed, about 0.4 times as long as head. Ocelli well developed; posterior pair scarcely separated from eyes, 25µm apart from each other in holotype. Postocular setae shorter than eyes, expanded; 105µm apart from each other, 8–9µm apart from eyes in holotype.Antennae ( Fig. 296 View FIGURES 290–296 ) about 1.8 times as long as head; segment VIII relatively slender, weakly constricted basally, narrowly joined to segment VII, about 0.8 times as long as VII; segment III almost as long as segment IV, much longer than VII; segment IV the largest; segments III and IV with three (1+2) and four (2+2 +1) sense cones respectively. Maxillary stylets not reaching postocular setae, wider apart, almost V-shaped; maxillary bridge weak. Pronotum ( Fig. 290 View FIGURES 290–296 ) about 0.6 times as long as head, 0.63 times in holotype, about 1.5 times as wide as long; almost smooth; five pairs of prothoracic setae expanded, am almost as long as aa, or a little longer; pa well developed, almost as long as postocular setae. Prospinasternum ( Fig. 291 View FIGURES 290–296 ) irregularly fan-shaped, 34µm wide in holotype; ferna and basantra largely developed; mesopresternum complete. Mesonotal lateral setae weakly expanded, 18µm long in holotype. Metanotum ( Fig. 292 View FIGURES 290–296 ) weakly sculptured with longitudinal reticulation; median pair of setae finely pointed, more than 20µm, their distance wider than distance between that seta and anterior margin of mesonotum, 42µm apart from each other, 33µm apart from anterior margin in holotype. Fore femur ( Fig. 295 View FIGURES 290–296 ) with about 5 small tubercles on inner-ventral surface at middle; fore tibia ( Fig. 294 View FIGURES 290–296 ) with a sub-apical dentate seta-bearing tubercle; fore tarsus with a distinct tooth ( Fig. 294 View FIGURES 290–296 ). Fore wing with 5 duplicated cilia; three sub-basal setae expanded, S1 shorter than S2, S3 the longest. Pelta ( Fig. 293 View FIGURES 290–296 ) trapezoid, sculptured weakly, about 1.6 times as wide as long in holotype. Tergites III – VIII S2 setae: III and IV expanded, V blunt or bluntly pointed, VI – VIII pointed. Tergite IX S1 setae blunt, much shorter than tube, S2 finely pointed, longer than S1, almost as long as tube or a little shorter; intermediate setae longer than half of S1. Tube 0.55 times as long as head in holotype, 2.3 times as long as wide; terminal setae about 1.9 times as long as tube .

Measurements (holotype female in µm). Body length 1680 (distended). Head length 187, from anterior margin of eyes 175, width across eyes 145, maximum width across cheeks 148, minimum width across base 118; eyes length 75; diameter of posterior ocelli 13–17; postocular setae 45–47. Maxillary bridge width 71. Antenna total length 335, segments III–VIII length (width) as follows: 46 (28), 47 (28), 42 (25), 41 (19), 38 (18), 30 (10). Pronotum length 118, width 179. Setae on prothorax: am 20–25, aa?20, ml 35, pa 43–46, epim about 50. Fore wing length 700. Sub-basal wing setae: S1 40 –42, S2 44 –45, S3 57. Pelta length 63, width 100. Tergite IX setae: S1 62–68, S2 90–100. Tube length 103, maximum width 45; terminal setae 195.

Male. Unknown.

Type material. Holotype: macropterous female, Indonesia, Bali, Tabanan, Jatiluwih (Peteli Temple), 867– 915m alt., on dead branches, 14.iii.2005, SO . Paratype: Indonesia, Bali, 1 female, Tabanan, Batu Sesa , ca 1250m alt., habitat uncertain, 14.viii.2006, SO .

Comments. This species is described from Bali, Indonesia, based on two females, but the habitat is uncertain. It may be included in the pictipes -group and may be closely related to N. andromorphus sp. nov. described above from Peninsular Malaysia. These two species have the fore femora with a series of small tubercles on the inner-ventral surface, and the ferna are somewhat well developed. However, tabananensia can be discriminated from andromorphus by the following features: dorsal surface of head almost smooth at middle; antennal segment III largely brown; antennal segment VIII more slender, about 0.8 times as long as segment VII; tube shorter, shorter than 0.6 times as long as head; terminal tube setae longer, much longer than 1.5 times as long as tube. It may also be related to N. dentipes sp. nov. from Indonesia and Singapore described above, but dentipes has the fore femur with two inner distinct tooth-like tubercles on ventral surface.
