Figure 28 Adult colour. General body colour brown. Fore wing membrane clear. Adult structure. Fore wing apex bluntly acute; surface spinules sparsely distributed, few or none in cells r1, cu2, c+sc; short setae on margins and veins (Fig. 28A). Antennae short (length 0.74; ratio AL:HW 1.28); genal processes short (ratio VL:GP 3.00) and rounded apically; medium short setae on vertex and short setae on thorax; distal proboscis segment medium-short (length 0.12); hind tibia slender and longer than head width (ratio HW:HT 0.92) (Fig. 28 B-D , F). Female terminalia (Fig. 28 G-H ): proctiger long, dorsal surface more or less straight, apex acute, anal ring long (ratio FP:RL 3.89); subgenital plate with slight medial bulge ventrally, acute apically; ovipositor apex with very reduced serrations (0-2 above, 0-2 below), valvulae dorsalis not strongly convex dorsally.

Unpigmented, short, not sinusoidal, no microsculpturing, pedicel not visible, tail lacking (Fig. 28E). Immature. Unknown. Host plant notes. Collected from glabrous morphotype. Island. Kauai. Distribution notes. Only known location is Kalalau Valley, Kokee State Park. Biology. Unknown. Etymology. The name refers to the small and elegant appearance with slender elongate female terminalia and long, slender tibiae (adjective in the nominative singular). Comments. Known from only one female specimen; the distinctly long, slender terminalia is unlike any other described species. Type material. Holotype female (slide mounted, BMNH). See Table 2 for details of type material examined for this study.
