Sueus insulanus sp. nov. female holotype, 2.0 mm A) dorsal view; B) lateral view; C) frons; D) posterolateral view. Description. Female: length 2.0– 2.6 mm , 1.82–2.08 × longer than wide. Frons weakly convex, with a distinct, sharply elevated, longitudinal carina extending from epistomal margin to upper level of eyes; surface dull, densely, and finely punctate-granulate, with fine, golden-brown setae. Antennal funicle 5-segmented; club conical slightly flattened, with three transverse sutures. Pronotum 1.2–1.44 × wider than long, widest slightly behind middle; lateral margin evenly arcuate, more strongly converging on anterior half; surface densely, finely granulate and weakly punctate, with scattered, long, golden-brown setae. Elytra 1.18–1.38 × longer than wide; sides weakly arcuate, apex narrowly rounded; discal striae very narrow, shining, lightly impressed, more strongly impressed toward declivity, strial punctures fine, shallow; discal interstriae much wider (2–4 × ) than striae, granulate, with 3 or 4 rows of long, fine, appressed, golden-brown setae. Declivity convex; surface as on disc except striae distinctly more deeply impressed, interstriae slightly narrower, fewer granules. Third tarsal segment entire. Male. Unknown. Etymology. L.= islander, a noun in apposition. Distribution. Papua New Guinea . Hosts. Unknown. Presumably mycetophagous.
