description: Blaste jambiense, sp. nov.
(Figs 67–77)
Male. Coloration (after ca 3 years in alcohol). Head brown. Epicranial suture dark brown; yellowish spots each side anterior to posterior margin of vertex. Eyes black. Ocelli pale, black centrally; a yellowish band each side of lateral ocellus extending to the anterior of eyes. Gena yellowish, unmarked. Antenna brown. Frons with median triangular brown mark. Clypeal suture dark brown. Postclypeus with brown striation; anteclypeus pale, labrum brown; maxillary palp pale, dark brown apically. Thorax: dorsal lobes dark brown yellowish along suture, lateral lobes yellowish. Fore wing (Fig. 67) suffused with light brown, pterostigma dark brown medially. Legs pale except tibiae and tarsal segments brown.
Morphology. IO:D 2; Ct 26 (t1), 3 (t2). Fore wing (Fig. 67) pterostigma broad and convex apically. Areola postica five-sided, first and second sections of vein Cu1a make a distinct angle; discoidal cell widening anteriorly. Hypandrium (Fig. 69) symmetrical with lateral spinous lobe, field of long setae medially to this. Phallosome (Fig. 70): parameres free distally anteriorly connected by a membrane, broadened and spinous distally. Epiproct (Fig. 71) trapezoidal, with laterobasal spinose projection. Paraproct (Fig. 71) with short basal sclerotised stem, apical broad hook, and field of about 42 trichobothria.
Dimensions. B 2.1; FW 4.03; HW 2.97; F 0.94; T 1.9; t1 0.65; t2 0.15; t1/t2 4.33; f1 0.87;f2 0.7; f1/f2 1.24.
Female. Coloration (after ca 3 years in alcohol). Head in general buff; epicranial suture dark brown, dark brown band each side extending to posterior margin of vertex. Eyes black. Ocelli pale, black centripetally. Frons with median triangular brown mark. Antenna brown. Clypeal suture dark brown. Postclypeus with dark brown striation; anteclypeus dark brown on the dorsal 1/3 otherwise pale; labrum dark brown. Maxillary palp pale, dark brown apically. Thorax: dorsal lobes dark brown pale along suture; lateral lobe yellowish brown. Wings (Fig. 72) suffused with light brown, pterostigma dark brown medially.
Morphology: IO:D 3.1; Ct 23 (t1), 2 (t2)
Fore wing (Fig. 72) as in male. Subgenital plate (Fig. 74) with long posterior lobe setose apically. Main plate with median keel basal to apical lobe and a curved row of long setae from posterior edge of lateral sclerotised area to anterior of plate. Gonapophyses (Fig. 75): ventral valve long and pointed apically, dorsal valve broad spinulate in the apical end; outer valve with very long setae and long posterior lobe. Spermapore plate as in Fig. 76. Epiproct (Fig. 77) trapezoidal with lateral sclerotised prongs. Paraproct (Fig. 77) with field of about 31 trichobothria.
Dimensions. B 3.0; FW 4.99; HW 3.0; F 0.98; T 1.8; t1 0.5; t2 0.16; t1/t2 3.13; f1 0.53; f2 0.44; f1/f2 1.2. Holotype male: INDONESIA, SUMATRA, Jambi, Leter W, beating Citrus, 1320m, 19.VI.1997. Paratypes: 28 males, 15 females: same data as holotype.

Remarks. The appearance of this species is reminiscent of that of the Australian Blaste lignicola (Enderlein), for which an augmented description of both sexes was given by Schmidt and Thornton (1992). The wing venation in both sexes of B. jambiense differs from that of B. lignicola in the shape of the areola postica, but the subgenital plate of the two species is very similar. It has a dense median band of setae basal to the apical lobe, and a sinuous band of setae from the posterior edges of the lateral sclerotised areas to the anterior of the plate. However, the median band of the above specimens extends to reach the sinuous band of setae. In addition, the outer gonapophysis valve of B. jambiense has a very distinct lobe, absent in B. lignicola. The hypandrium of the male genitalia also differs in the two species. In the above specimens the hypandrium is serrated posteriorly and has two lateral serrated lobes, whereas this feature is absent in the hypandrium of B. lignicola.
The species’ name refers to the type locality.
