Diagnostic description

Holotype, male (Fig. 35a). Length 3.14 mm. Color black; basal half of elytra with large orange spot. Body elongate-subovate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Rostrum slender; dorsally with distinct median costa and pair of narrow submedian ridges; at base with erect white clavate scales, apically replaced by bristles. Eyes large, medially approximate. Pronotum densely punctate-reticulate; sides anteriorly with punctures containing small white scales. Elytra subglabrous, irregularly punctate with minute punctures; striae obsolete; basal margin with ridge extending behind humeri, bordered by row of small indistinct punctures. Femora with tooth in apical half. Mesofemur and metafemur dorsally sparsely squamose with white scales. Metafemur with smooth dorsoposterior edge; subapically without stridulatory patch. Abdominal ventrites 1–2 laterally swollen, medially concave; ventrite 2 posteriorly truncate, posterior face markedly projecting over ventrite 3. Aedeagus (Fig. 35b) subapically slightly widened; apex subangulate, asymmetrical, shifted to left; transfer apparatus dentiform, basally supported by crescent-shaped sclerite; ductus ejaculatorius subapically without bulbus. Intraspecific variation. Length 3.27–3.53 mm. Female rostrum dorsally subglabrous, with submedian rows of minute punctures, with lateral furrow containing row of sparse setae. Female abdominal ventrites 1–2 convex.

Material examined

Holotype (SMNK): ARC1831 (EMBL # HE616108), PAPUA NEW GUINEA, Eastern Highlands Prov., Okapa, Kimiagomo village, Afiyaleto, S06°25.593', E145°34.862', S06°25.212', E145°35.498', 1911 m, 18-III-2010.

Distribution

Eastern Highlands Prov. (Okapa). Elevation: 1911–1940 m.

Biology

Etymology

This epithet is based on the Greek noun helios (sun) in apposition and refers to the bright orange spot on the elytra.
