Introduction

This species was described by Kirkaldy (1906) from Bundaberg in SE Queensland and further details of the male genitalia were added by Kirkaldy (1907). Fennah (1965) recorded the species from Victoria as Eumetopina histrionica but Bellis & Donaldson (2015), who extended the known range of the species to the Wet Tropics, considered Fennah had misidentified the species and the Victorian record is therefore doubtful. It is unknown if this species is capable of transmitting diseases.

Diagnosis

Vertex smoky brown; clypeus yellowish testaceous; frons, antennae, sterna, legs and tegmina yellowish, the last named being broadly black basally, this continuing on to mesopleura. Pronotum, scutellum and basal half of abdomen whitish testaceous, a broad black band across the middle above; apical of this, pale red brown, becoming paler and more sordid apically. Sternites apically pale red brown. Genital segment mostly black. Tegmina reaching to a little beyond middle of body, apically truncate. Length: (male), 2.5 mm. (Kirkaldy 1906)

The male pygophor is very remarkable. The lip is strongly produced on each side, and there are two smaller projections between these. The genital styles are elongate and bent at the apex. The aedeagus is horizontal and is subcultrate with, apparently, a long projection from one side. (Kirkaldy 1907)

Anterolateral carinae meeting before apex of vertex, basal compartment of vertex longer than wide and about as long as anterior compartment. Frons about 2.6 times as long as width at widest point, widest at about 1/4 from apex. Lateral margins of frons convex, widening apically, slightly flattened near ocelli. Antennae reaching apex of frons, segment I conical, about 2.1 times as long as wide, segment II about 2.9 times as long as wide and about 1.7 times as long as segment I. Ocelli and blemmata (fuscous spot surrounding the ocellus) present. Apical rostrum segment about 2.9 times as long as wide. Pronotum lateral carinae slightly curved, reaching hind margin, parallel apically. Mesonotum medial and lateral carinae reaching hind margin. Hind tibial spur formula 5:7:4, calcar thin tectiform with 1 row of about 35 teeth and with apical spine. Claval suture absent in brachypterous tegmen, Sc+R fork of brachypterous tegmen distad of Cu1 fork and basad to junction of anal veins and sutural margin of tegmen. Male pygophore with two long and two short medioventral processes. Aedeagus with reflexed dorsal tag, long narrow ventral process arising basally and smaller process subapically on right-hand side.
