Male. Coloration (after ca 3 years in alcohol). Head yellowish. Epicranial suture dark brown, broad brown band on each side of epicranial sulcus extending to posterior margin of vertex. Eyes black, suffused with grey. Ocelli pale, dark brown centripetally. Frons with median dark brown V-shaped mark contiguous to the central ocellus. Frontovertical suture pale; clypeal suture pale medially otherwise dark brown. Postclypeus pale; clypeal suture pale; anteclypeus dark brown on dorsal 1/3 otherwise pale, labrum dark brown, maxillary palp pale, dark brown on the tip of the apical segment. Gena unmarked. Antenna, scape and pedicel dark brown, flagellum brown. Thorax brown; dorsal lobe dark brown, yellowish along suture. Wings (Figs 35, 36) with brown pattern. Legs pale except tibia and tarsal segments of the fore legs dark brown.
Morphology. IO:D 0.56; Ct 18(t1), 2(t2). Eyes very large. Fore wing (Fig. 35) pterostigma broad, concave apically, areola postica five-sided. Hypandrium (Fig. 37) symmetrical with median posterior projection, a pair of lateral spinous lobes, the median sclerite rectangular and with long setae, the lateral pair of sclerites spinose. Phallosome (Fig. 38): parameres free distally, serrated posteriorly, anteriorly connected by membrane. Eighth tergite with median keel. Epiproct (Fig. 39) rounded, with small basal projection; paraproct (Fig. 39) with long basal sclerotised bar and field of about 18 trichobothria.
Dimension s. B 1.7; FW 2.45; HW 1.77; F 0.5; T 0.93; t1 0.28; t2 0.08; t1/t2 3.5; f1 0.23; f2 0.18; f1:f2 1.28. Female. Coloration (after ca 3 years in alcohol) similar to male except light brown mark mesial to each orbit.
Morphology. IO:D 4.0; Ct 18 (t1), 2(t2). Eyes small. Fore wing (Fig. 40) pterostigma broad apically, areola postica five-sided. Subgenital plate (Fig. 42) with distinct Y- shaped sclerotisation, posterior lobe long, tapering apically, apical third with long setae. Gonapophyses (Fig. 43): ventral valve long, pointed apically; dorsal valve broad, narrowing to short pointed apex; outer valve with long posterior lobe. Spermapore plate (Fig. 44); epiproct with lateral sclerotised prongs; paraproct (Fig. 45) with field of about 20 trichobothria.
Holotype male: INDONESIA, SUMATRA, South east, Way Kambas National Park, Kiara Tunggal, secondary forest, 100m, beating, 29.XII.1995, ESK. Paratypes: 1 male, 1 female, same data as holotype. Other specimens examined: SUMATRA, Way Kambas National Park, Way Kanan, mixed secondary forest, 150m, 1 male, 3 females, 21.XII. 1995, ESK; Way Kambas National Park, Rawa Bulus, mixed secondary forest, 100m, 3 females, 23.XII.1995, ESK; Way Kambas National Park, Kali Biru, mixed secondary forest, 40m, 1 female, 31.XII.1995, ESK; Way Kambas National Park, Way Kanan, mixed secondary forest, 20m, 1 female, 1.VII.1997. ESK; Way Kambas National Park, Kali Biru, mixed secondary forest, 20m, 2 males, 7 females, 2.VII.1997, ESK; Kerinci Seblat National Park, Gunung Tujuh, mixed primary forest, 1600–1800m, 4 males, 3 females, 23.I.1997, ESK; Gunung Leuser National Park, Lawe Gurah, mixed primary forest, 325– 360m, 5 females, 5.VI.1997, ESK.
Remarks. On wing venation and the details of the genitalic characters, the above specimens fall into Javablaste. This species differs from the other two species described previously, J. merapiensis and J. aidab (Endang et al. 2002), on the posterior accessory sclerite of the hypandrium. The median accessory sclerite of the hypandrium is rectangular instead of trilobed as in J. merapiensis and J. aidab. The epiproct of the two last species is hooked anteriorly, whereas the epiproct of J. junithai has a small projection.
The species is named for I.K. Junitha in appreciation of his help to ESK during her field work in Sumatra.
