Figs. 1M–P; 4C, 7F, 9B D ia g no si s. E c c op t o cera k u k o n a (Kauaʻi) is most similar to E. foetorivorans (Butler), which is not known from Kauaʻi and averages slightly smaller (FWL 6.3–7.7 in E. kukona, 4.2–7.1 mm in E. foetorivorans). Males can be distinguished most easily by their red-orange tegulae (dark brown or gray in some specimens), and rounded uncus (triangular in E. foetorivorans). Females are exceedingly similar to E. foetorivorans, but are typically darker, with less contrasting coloration on the forewing, often with mahogany or orange scales throughout. There is a conspicuous cup-like cavity on the left side of the ostium of E. kukona (this structure is absent or only weakly developed in E. foetorivorans), but it is easily obscured in slide-mounted or inadequately stained genitalia preparations.

Dorsal surface of FW (Fig. 1M; FWL: 6.3–7.6 mm) with costal fold to approximately 0.55× FW length; ground color dark brown to black, often with intermixed reddish-orange scales; dorsal strigulae variably developed, most often white or light gray, but occasionally darker gray or nearly obscured, often entirely shaded between with nearly concolorous light gray, less commonly well-separated with darker scales; basal strigulae typically only present as a small gray patch of scales near the base of inner margin; medianstrigulaevariablydeveloped, often present as a small triangular patch of gray scales, rarely extending onto costal fold, where it can be gray or reddish-orange; subterminal fasciae well-developed, broad, parallel-sided, complete to near end of cell. Ocelloid patch composed of 5-6 silver patches of varying size in a U-shaped arrangement on a variable field of black, gray, white, or red field; open on the costal half; with 3 short black streaks on the inner surface of the distal margin. Four pairs of costal strigulae present, white, but often heavily obscured by metallic blue-gray scaling such that very littlewhiteisvisible.Smallsubapicalnotch present along termen; fringe variable, most often gray or black scales, apices white.Ventral surface of FW brown,small patches of pale gray or white present at costal strigulae, but often faint, typically only terminal pair visible. Dorsal surface of HW entirely brown, paler basally; cubitalpectenwell-developed; analregion with a small extension. Ventral surface of HW pale brown. Abdomen. Vestiture of abdomen grayish-brown. Genitalia (Fig. 4C) with uncus with a short neck and a broad, slightly inflated, rounded apex; socius present as a slightly elevated patch bearing moderately long, hair-like setae; tegumen high, arching, with long, hair-like setae on lateral surface; gnathos present as a pair of triangular lobes and a pair of weakly sclerotized, thin arms; valvae slender, curved, asymmetrical; base of valvae swollen, with a large subtriangular basal excavation; neck of valvae slightly constricted; cucullus well-developed, with a small dorsal, mound-like inflation; apex of cucullus with a large, sharp, ventrally directed spike-like process; right valva slightly longer, more curved than left valva; juxta broad, triangular; caulis long, fused to anellus phallus robust, slightly irregular and swollen at base, with long, upcurved apical extension; vesica with a dense patch of long, thin, deciduous, spine-like cornuti.
Female (n=67). Head. Similar to male except antenna without antennal notch. Thorax. Similar to male except slightly larger (Figs 1N–P; FWL: 6.5–7.7 mm), more variable in wing pattern, often with much more extensive reddish-orange ground color and metallic blue-gray scaling on costal strigulae; costal fold, anal extension absent. Abdomen. Vestiture of abdomen similar to male. Genitalia (Fig. 7F) with papillae anales subtriangular, apically broad, acute, with shallow anteromedial notch, flattened and roughened on ventral surface; apophyses posteriores approximately 0.5× length of S7; apophyses posteriores approximately 0.67× length of S7; sterigma rectangular,widening slightly posteriorly; ostium elliptical; right side of lamella antevagenalis without any modified structure obscuring the ostium, but may occasionally be slightly thickened, left side of ostium with conspicuous, small, cup-like cavity; ductus bursae short, with a long membranous extension (in some well-stained genitalia preparations this extension appears to be slightly sclerotized on the interior wall); colliculum present, well sclerotized, ring-like, incomplete on ventral side; ductus bursae broad, basal half well-sclerotized to ductus seminalis; corpus burse globose, with a pair of parallel, ridge-like processes present on interior dorsal wall; a large, circular sclerotized patch present on the dorsal wallofcorpusbursae; twolarge,opposite, thorn-like signa present on the dorsal and ventral walls; inner surface of corpus bursae densely covered in a fine network of minute spinules.
Biology. Eccoptocera kukona has been reared from tied leaves of ʻōhiʻa lehua (Metrosideros polymorpha; Myrtaceae).
Distribution. Eccoptocera kukona is the most widespread and common species of Eccoptocera on Kauaʻi, where it can be found in virtually all places where its host, ʻōhiʻa lehua (Metrosideros polymorpha), grows. It has been collected at elevations from 265–1265m in lowland wet forest, mid-elevation mesic forest, and high elevation wet forest and bogs.
Etymology. This species is named in honor of Kūkona, one of the signature chiefs of ancient Kauaʻi and the father of the most well-known Kauaʻi chief, Manokalanipō.
Comments. This species was listed as “ Eccoptocera new species 1” by Zimmerman (1978).
Conservation Status. Eccoptocera kukona is likely secure. It is widespread and common, sometimes even abundant in native forest wherever ʻōhiʻa lehua (Metrosideros polymorpha) occurs.
