Setopsocus clematoscenoides , sp. nov.

( Figs 6–11 )

Male unknown

Female. Coloration (after ca 3 years in alcohol). Head ground colour cream. Epicranial suture light brown. A transverse broad dark brown band from posterior of vertex to back of head capsule and across gena. Eyes greyish black; ocelli pale, black centripetally. Frons with three parallel brown striae between lateral ocellus and eyes and triangular brown mark medially. Antennal socket pale-bordered. Antenna dark brown except scape, pedicel and first flagellar segment pale. Clypeal suture dark brown. Postclypeus pale laterally, medially with five dark brown striations, anteclypeus whitish. Labrum dark brown. Apical segment of maxillary palp dark brown otherwise brownish. Thorax: antedorsum of mesothorax dark brown almost black; dorsal lobe with creamy patches; pleura dark brown. Fore wing ( Fig. 6 ) with brown pattern, pterostigma dark brown; hind wing ( Fig. 7 ) suffused with light brown. Legs yellowish brown except coxa, tip of tibia and second tarsal segment dark brown

Morphology. IO:D 3.0, eyes small. Head setose. Fore wing ( Fig. 6 ) veins setose on basal 1/3; pterostigma triangular, apex rounded; vein Cu1a meeting M at a point; sides of discoidal cell parallel. Subgenital plate ( Fig. 8 ) with pigmented area roughly T-shaped and transverse narrow dark brown, sclerotised bar connection to forked pigmented pattern on short posterior lobe, with apical setae. Gonapophyses ( Fig. 9 ): ventral valve elongate, tapering apically; dorsal valve broad, narrowing to short bluntly pointed apex; outer valve transverse with extremely long setae, posterior lobe short. Epiproct ( Fig. 10 ) with lateral sclerotised prongs. Paraproct ( Fig. 10 ) with field of about 31 trichobothria. Spermapore plate as in Fig.11 .

Dimensions. B 3.85; FW 5.8; HW 3.8; F 1.18; T 2.4; t1 0.6; t2 0.25; t1/t2 2.4; Ct 23 (t1), 3 (t2); f1 1.52; f2 1.68; f1/f2 0.74

Holotype female: INDONESIA, SUMATRA, North, Sibolangit, primary protected forest, 500m, 31.I.1997, ESK.

Remarks. This species differs from other previously described species in coloration and venation of the fore wing, and in the areola postica meeting M at a point. The subgenital plate has a distinct transverse sclerotised bar on the main plate.

The species name refers to the similarities of wing pattern to those of the related genus Clematoscenea .
