Javablaste ramonai , sp. nov.

( Figs 46–55)

Male. Coloration (after ca 3 years in alcohol). Head ground colour cream: epicranial suture brown. Eyes greyish black; clypeal suture light brown. Gena unmarked. Antenna dark brown. Postclypeus with light brown striation, dorsal half of anteclypeus dark brown, otherwise whitish; labrum dark brown, maxillary palp pale except apical segment dark brown. Thorax: dorsal lobe brown, pale along suture, lateral lobes pale. Fore wing ( Fig. 46) suffused brown, pterostigma dark brown, dark brown cloud on apices of all radial cells; hind wing ( Fig. 47) suffused with brown.

Morphology. IO:D 0.5; Ct 23 (t 1), 2 (t 2). Eyes prominent. Fore wing ( Fig. 46) pterostigma broad, convex apically, areola postica five-sided. Hypandrium ( Fig. 48) symmetrical, with median oblong posterior lobe, a pair of lateral rounded spinous lobes. Phallosome ( Fig. 49): parameres free distally, serrated posteriorly, anteriorly connected by membranes. Epiproct ( Fig. 50) rounded, with triangular basal projection. Paraproct ( Fig. 50) with long basal sclerotised bar and field of about 30 trichobothria.

Dimensions. B 2.5; F 0.77; T 1.52; t 1 0.47; t 2 0.13; t 1 /t 2 3.62; f 1 0.9; f 2 missing.

Female. Coloration (after ca 3 years in alcohol) similar to male except light brown confluent patches each side of epicranial suture extending to the posterior margin of vertex and mesial to each orbit. Brown band on the ventral margin of antennal socket.

Morphology. IO:D 2.85; Ct 24 (t 1), 2 (t 2). Eyes small. Fore wing ( Fig. 51): pterostigma broad, convex apically, areola postica five-sided. Subgenital plate ( Fig. 53) posterior lobe long with long setae on the posterior margin; main plate with lateral broad sclerotisation and dark brown transverse curved bar in basal area. Gonapophyses ( Fig. 54): ventral valve long with long apical setose pointed spine; dorsal valve broad, narrowing to short pointed apex; outer valve with short posterior lobe and with long setae. Epiproct ( Fig. 55) with lateral sclerotised prong. Paraproct ( Fig. 55) with field of about 26 trichobothria.

Dimensions: B 2.8; FW 3.75; HW 2.8; F 0.67; T 1.38; t 1 0.4; t 2 0.12; t 1 /t 2 3.33; f 1 0.67; f 2 0.56; f 1 /f 2 1.2

Holotype male: INDONESIA, SUMATRA, West, Jambi, Leter W, beating, citrus, 1320m, 19.VI. 1997, ESK. Paratypes: 3 males, 1 female, same data as holotype.

Other material examined: SUMATRA, West, Kerinci Seblat National Park, Gunung tujuh, beating, cinnamon, 1360m, 1 female, 23.I. 1997, ESK; SUMATRA, West, Gunung Cermin, cinnamon, 1000m, 3 females, 24.I. 1997, ESK.

Remarks. The male genitalia of this species clearly distinguish it from its congeners; the median hypandrial accessory sclerite is oblong whereas in J. merapiensis and J. aidab it is trilobed and in J. junithai sp. nov. this sclerite is rectangular. Furthermore, the lateral pairs of the accessory sclerites in J. merapiensis , J. aidab and J. junithai sp. nov. are more or less rectangular, but rounded in this species. From the female genitalia, the species resembles the unassigned females of Javablaste (see Endang et al. 2002) but differs from them in details of subgenital plate sclerotisation and the gonapophyses; the transverse sclerotised bar of unassigned female Javablaste is much deeper than that of species above; the posterior lobe of the outer gonaphophysis valve is longer and the ventral valve lacks any long apical setose spine.

The species is named for Yan Ramona, in appreciation of his help to ESK during her field work in Sumatra.
