(Figs 21–31)
Male. Coloration (after ca 3 years in alcohol). Head yellowish brown. Epicranial suture dark brown. Eyes black. Ocelli pale, black in the centripetal margin. Frons vertex suture dark brown. Postclypeus with light brown striation; anteclypeus brown on the dorsal half, otherwise pale, labrum dark brown, maxillary palp brownish dark brown apically. Gena unmarked. Antenna dark brown; flagellar segments with narrow pale apical band. Thorax brown, dorsal lobe of thoracic terga dark brown. Fore wing and hind wing (Figs 21, 22) suffused brown.
FIGURES Neoblaste ketambiense sp. nov., male: 17, fore wing; 18, hind wing; 19, hypandrium; 20, paramere.
Morphology. IO:D 1.8; Ct 22(t1), 2(t2). Fore wing (Fig. 21) pterostigma smoothly rounded posteriorly, discoidal cell wide anteriorly, areola postica appearing five-sided. Hypandrium (Fig. 23) symmetrical, with a pair of median fork-shaped processes, a pair of large lateral, very slightly serrate, free accessory sclerites short, abruptly angled medially. Phallosome (Fig. 24): parameres separate, terminating with apical hooks, connected with tissues anteriorly. Epiproct pentagonal with field of short setae medio basally. Paraproct (Fig. 25) with field of about 20 trichobothria. Ninth tergite (Fig.25) with posteromedian bar and lateral clunial tubercles.
Dimensions. B 1.6; FW 2.45; HW 1.8; F 0.48; T 0.94; t1 3.3; t2 0.10; t1/t2 33; f1 0.45; f2 0.36; f1/f2 1.25. Female. Coloration (after ca 3 years in alcohol), similar to male.
Morphology. IO:D 2.2 Ct 20(t1), 2(t2). Fore wing and hind wing (Figs 26, 27) as in male. Subgenital plate (Fig. 28) well-defined, short posterior lobe tapering to rounded apically, setose; main body of plate with a roughly Y-shaped field of long setae medially on a pair of strong sclerotised plates. Gonapophyses (Fig. 29) ventral valve very long terminating in a long sharp spine; dorsal valve broad with apical spine, a tuberculate field on the ventral edge; outer valve transverse bearing very long setae. Spermapore plate (Fig. 30). Epiproct and paraproct (Fig. 31), epiproct trapezoidal with lateral long prongs; paraproct with field of about 21 trichobothria.
Dimensions. B 1.8; FW 2.67; HW 1.85; F 0.57; T 1.05; t1 3.3; t2 0.10; t1/t2 33; f1 0.48; f2 0.43; f1/f2 1.12
Holotype male: INDONESIA, SUMATRA, South East, Way Kambas National Park, Kalibiru, mixed secondary forest, 20m, beating, 2.VII.1997, ESK. Paratypes: 1 male, 2 females, same data as holotype. Other specimens examined: Sumatra, South East, Way Kambas National Park, Way Kanan, mixed secondary forest, 20m, beating, 2 males, 1 female, 30.VI.1997, ESK.
Remarks. This species is clearly distinguishable from its Oriental congeners by features of the genitalia. The male hypandrium is somewhat similar to that of N. alticola Thornton from Bali, in having large lateral accessory sclerites. However, the hypandrial sclerites of N. piscata are larger than in N. alticola and are abruptly angled medially, in contrast to their gradual taper in N. alticola. The parameres are unusually slender within this complex, and distinctive. The female differs from that of N. alticola in having a much narrower apical lobe to the subgenital plate, and more defined sclerotisation at the base of this lobe.
The species name, from Latin for ‘fisher’, alludes to the fish-hook shape of the male paramere.
