Male antennae each with 20–21 flagellomeres. Forewing length. Male 1.8–1.9 mm (n=5). Male genitalia ( Figs 6–9 ). Short sharp spur present medially on abdominal sternite VII. Median process on abdominal sternite VIII stoutly spatulate, length about 5 times width at 1/2 length. Abdominal sternite and tergite IX fused, laterally only slightly produced posteriorly, dorsally deeply concave. Gonopods inserted asymmetrically; right well to left of centre; both bearing brushes of stout black setae. Phallic apparatus ( Fig. 9 ) slender, elongate, constricted at 1/4 length at which constriction arises short, threadlike titillator; short sharp spine at about 2/3 length. Phallic sheath ( Fig. 8 ) short, broad at base; extended posteriorly as elongate, curving sheath, about 1/2 length of gonopods, with setae apically; basal structures difficult to interpret. Female not associated with certainty. Holotype male: Province Nord , Ponandou Tiôgé River at Kögi , 3.9 km SSW Touho , 20°49.043'S , 165°13.551'E , 25 m , 26.xii.2003 , light trap , loc#100, leg.
