(Figs 17–20)

Female unknown

Male. Coloration (after ca 3 years in alcohol). Head ground colour yellowish. Epicranial suture brown, light brown mark each side of epicranial suture extending to posterior margin of vertex and mesial to each orbit. Ocelli pale, black along centripetal margin. Frons vertex suture brown. Gena unmarked. Antenna brown; flagellar segments with narrow pale apical band. Postclypeus with light brown striation; anteclypeus pale; labrum brownish; maxillary palp pale. Thorax and legs yellowish brown. Fore wing (Fig.17) suffused light brown with a broad brown band on the basal half.

Morphology. IO:D 1.17; Ct 18(t1), 2(t2). Fore wing (Fig.17) pterostigma smoothly rounded posteriorly, discoidal cell wide anteriorly, areola postica appearing five-sided. Hypandrium (Fig.19) symmetrical, with a pair of apical fork-shaped projections, and serrate free accessory sclerites directed medially. Phallosome (Fig. 20) parameres separate, with subapical boss and very large spine. Paraproct and epiproct missing in preparation.

Dimensions. B 1.9; FW 2.64; HW 1.92; F 0.5; T 0.10; t1 0.34; t2 0.01; t1/t2 34; f1 0.55; f2 0.45; f1/f2 1.22.

Holotype male: INDONESIA, SUMATRA, North, S.E Ache, Gunung Leuser National Park, Ketambe, mixed secondary forest, 325–560m, beating, 6.VI.1997, ESK.

Remarks. In general the parameres resemble those of the species described originally as N. quinquedentata Li from China (now known as Pentablaste pentasticha Li ) and N. brunnea Endang & Thornton , but males differ in details of the sclerotised median lobe processes of the hypandrium. N. timorense Endang, Thornton & New (2002) also has sclerotised median lobe processes, but it differs from the present species in that the hypandrium of N. timorense has multiple lobes, whereas the sclerites on the hypandrium of the present species consist of only a pair.

The species name refers to the type locality.
