Introduction

Kirkaldy's original description (Kirkaldy 1907) was based on brachypterous males. Macropterous forms have not been found although this might be an artefact of restricted collecting. This species is only known from the wet tropics of North Queensland.

Diagnosis

Closely allied to D. puella [=Coronocella sinhalana (Kirkaldy)], but (in the short-winged form at least) the tegmina are deeply fuscous and more opaque; basal half of commissure and a tiny spot near the apex internally whitish. The median keel of the frons is rather thick and whitish, and the lateral keels of the pronotum are straight and reach the hind margin. Spur with 33 spines. Male pygophor suboval, broadly produced near the anal tube, which has 2 projections from the ventral wall. The genital styles are widened and truncate apically, the outer angle rounded, the inner acutely produced. Length 1 7/8 mm (brachypterous form only known) (Kirkaldy 1907)
