Male. Coloration (after ca 3 years in alcohol). Head ground colour yellowish brown. Epicranial suture dark brown, confluent brown patches each side extending to posterior margin of vertex and mesial to each orbit. Eyes black. Ocelli pale black centripetally. Frons with median triangular dark brown mark. Clypeal suture dark brown. Gena unmarked. Antennal socket with light brown band. Antenna dark brown. Postclypeus with brown striation; anteclypeus yellowish except dorsal third dark brown; labrum and maxillary palp dark brown. Thorax brown.

Morphology. IO:D 1.33; Ct 19 (t1), 2 (t2). Fore wing ( Fig. 56 ). Pterostigma broad, convex apically; areola postica five-sided. Hypandrium ( Fig. 58 ) symmetrical with median parallel oblong serrated lobes, a pair of lateral spinose lobes, a triangular sclerotised plate anterior to this. Phallosome ( Fig. 59 ): parameres rounded, serrated and free distally, anteriorly connected by membranes. Epiproct ( Fig. 60 ) squarish with broad basal spinous projection. Paraproct ( Fig. 60 ) with broad bifid basal sclerotised bar, apical broad hook and field of about 26 trichobothria.

Dimensions. B 1.5; FW 2.43; HW 1.77; F 0.56; T 0.92; t1 0.25; t2 0.1; t1/t2 2.5; f1 0.5; f2 0.38; f1/f2 1.32. Female. Coloration (after ca 3 years in alcohol) as in male.

Morphology. IO:D 3; Ct 18 (t1), 2 (t2). Fore wing ( Fig. 61 ) similar to male. Subgenital plate ( Fig. 63 ) posterior lobe long, rounded and setose apically; the main plate with very distinct basal V-shaped sclerotisation and broad lateral sclerotised area. Gonapophyses ( Fig. 64 ) ventral valve very long with long apical pointed setose spine; dorsal valve broad, pointed apically; outer valve transverse with long setae, apical lobe small and short. Spermapore plate ( Fig. 65 ). Epiproct ( Fig. 66 ) trapezoidal with lateral pointed prong. Paraproct ( Fig. 66 ) with field of about 23 trichobothria.

Dimensions. B 2.0; FW 2.64; HW 2.05; F 0.5; T 1.02; t1 0.3; t2 0.11; t1/t2 2.73; f1 0.5; f2 0.4; f1/f2 1.25.

Holotype male: INDONESIA, SUMATRA, SE, Way Kambas National Park, Way Kanan, beating, mixed secondary forest, 20m, 2.VII.1997, ESK. Paratypes: 1 male, 4 females: same data as holotype.

Other specimens examined: INDONESIA, SUMATRA, SE, Way Kambas National Park, Way Kanan, beating, mixed secondary forest, 20m, 1 female, 30.VI.1997, ESK; Way Kambas National Park, Rhino Sanctuary, beating, mixed secondary forest, 20m, 1 male, 2.VII.1997, ESK.

Remarks. This species differs from all previously described species ( J. merapiensis and J. aidab , J. junithai sp. nov. and J. ramonai sp. nov.), in the details of the median posterior lobe of the hypandrial sclerotisation, the eighth sternite and features of the epiproct. It somewhat resembles that of Neoblaste harpophylla Li from China, but the phallosome and the hypandrial features differ clearly.

This species is named for I.B. Darmayasa, in appreciation of his help to ESK during her field work in Sumatra.
