Introduction

A small (< 5mm) semimacropterous species with a long second antennal segment. It was described from Bellenden Ker but Donaldson (1983) lists numerous localities for the species in Cape York Peninsula and the wet tropics of coastal North Queensland.

Diagnosis

♂ length of body 4.4–5.0 mm, length of tegmen 3.3–3.9 mm; ♀: length of body 4.9–5.1 mm, length of tegmen 3.8–4.0 mm. Colour. Body light brown, with variable darker markings. Frons with 5 or 6 red to brown marks lateral and adjacent to submedian carinae, apical marks sometines extending to lateral margins. Antennae with 2 bands often pale and incomplete on segment 1, and 3 dark bands on segment 2. Postclypeus and apical part of clypeus often dark, producing together with dark areas on fore coxae and femora a dark transverse bar on ventral surface. Vertex, pronotum and mesonotum usually with variable dark markings along or adjacent to carinae. Tibiae and tarsi with distinct dark banding. Tegmen light hyaline, with dark areas on and adjacent to longitudinal veins giving mottled appearance, cross veins and adjacent parts of longitudinal veins whitish. Head. Vertex in midline 1.4–1.8 x basal width, widest just before rounded apex; sides straight or nearly so; posterior margin usually convex, sometimes straight; submedian carinae meeting before apex, subobsolete at apex; basal compartment about as wide as or slightly wider than long. Frons in midline 1.6–1.8 x greatest width; submedian carinae slightly converging at base and apex, not meeting, becoming obsolete before apex. Segment 2 of antennae 2.2–2.6 x length of segment 1. Thorax. Pronotum with strong median carina. Mesonotum with strong carinae, outer pair reaching posterior margin. Hind tibiae with single lateral spine in addition to basal and apical ones. Tegmen short, reaching anal segment, claval suture present; Cu forked distal to claval fork, each branch reuniting before apex; M forked, at least 2 rows of cross veins; apical veins complex. Anal segment of ♂ in lateral view with ventrolateral portion slightly produced posteriorly, with rounded lower angle and somewhat acute upper angle. Pygofer with median projection truncately rounded, just reaching level of broadly rounded ventrolateral margins. Genital style in ventral view with basal half robust, nearly parallel-sided, outer margin with broad rounded lateral projection just apical to midpoint and concave in apical third.
