sp. nov.

Clematoscenea smithersi View in CoL , sp. nov.

( Figs.1–5 View FIGURES 1 – 5 )

Male. Unknown.

Female. Coloration (after ca 3 years in alcohol). Head ground colour creamy brown. Epicranial suture brown with faint brown mark each side extending to posterior margin of vertex and mesial to each orbit. Eyes greyish black. Ocelli pale, with black protuberant crescent centripetally; Antenna brown except scape, pedicel and first flagellar segment yellowish; Gena brown, clypeal suture brown. Postclypeus with brown striation, dorsal half of postclypeus brown otherwise whitish; Labrum dark brown. Maxillary palp brown, except apical segment dark brown. Thorax dark brown, buff along sutures. Fore wing ( Fig. 1 View FIGURES 1 – 5 ) with brown pattern, pterostigma dark brown. Hind wing ( Fig. 2 View FIGURES 1 – 5 ) suffused light brown. Legs yellowish brown except first tarsal segment and apex of tibia dark brown.

Morphology. IO:D 4.09, eyes very small, ocelli small. Head setose; Fore wing ( Fig. 1 View FIGURES 1 – 5 ) with basal veins with two rows of setae; pterostigma deep and triangular, apex rounded; areola postica with narrow apex, cell M3 narrow and vein Cu1a parallel with vein M3. Subgenital plate ( Fig. 3 View FIGURES 1 – 5 ) with pigmented area roughly Tshaped, transverse region of T connected by narrow sclerotised area to fork-shaped apical sclerotisation; posterior lobe short with long apical setae. Gonapophyses ( Fig. 4 View FIGURES 1 – 5 ) ventral valve slender; dorsal valve broad, with extensive field of spicules ventrally, narrowing to short pointed apex, setose on the ventral edge; outer valve with fairly long setae and long posterior lobe. Epiproct ( Fig. 5 View FIGURES 1 – 5 ) with apical sclerotised prongs. Paraproct ( Fig. 5 View FIGURES 1 – 5 ) with field of about 39 trichobothria.

Dimensions. B 6.0; FW 7.0; HW 5.02; F 1.5; T 3.0; t1 0.85; t2 0.3; t1/t2 2.83; Ct 32 (t1) 5 (t2); f1 1.85; f2 2.13; f1/f2 0.87.

Holotype female: INDONESIA, SUMATRA, North, Prapat, beating pine in protected forest, 1220m, 1.II.1997, ESK.

Remarks. This species is clearly referable to Clematoscenea on the form of fore wing cell M3, which has been regarded as almost wholly diagnostic, despite some slight variations in form amongst New Guinea species. Of 10 described New Guinea species in this genus, only C. goilala Smithers and Thornton has setae on the basal fore wing veins. C. goilala is known only by the male, from the Owen Stanley Range in eastern Papua New Guinea. The two species have very differently marked fore wings: in C. goilala the posterior margin along the apical half is wholly dark, and the central region of cell R5 unmarked. The fore wing pattern is similar to that of C. lemniscata , above, and otherwise most closely resembles that of C. macalpinei Smithers & Thornton. It differs in having cell M1 pale and far more extensive pigmentation in the discoidal cell.

The species is named for Dr C.N. Smithers, whose studies laid the foundation for interpreting Clematoscenea in the region.
