  Type species:

   Dingkana borealis Goding, 1903 by original designation.

Introduction

This is one of two Australian genera in which the lateral pronotal processes are completely missing, the other being Terentius Stål. Dingkana borealis is more elongate and considerably more setose than species of Terentius and has the pronotum less globosely convex. Although the genus is currently monotypic, based on D. borealis from the wet tropics of North Queensland, Day (1999) recognised an undescribed species on Darnley Island, in Torres Strait, and said that additional species were known in Papua New Guinea. Goding (1903) gave the etymology of the name as "dingkan — an insect, in the Koka-Yimidir language".

Diagnosis

Head triangular, punctured, pubescent, lobed on each side on lateral borders; ocelli above a line passing through centre of eyes to which they are a little nearer than to each other. Prothorax rises convexly from base into the form of a dome, unarmed above lateral angles, coarsely punctured, median longitudinal carina anteriorly absent or obsolete; posteriorly the dorsum lightly descends into the posterior process which is very broad at base, gradually narrowed to middle, then attenuated to apex which is decurved reaching apex of abdomen; sides and dorsum of posterior process lightly sinuate. Tegmina lanceolate, vinaceous, opaque at base, with three discoidal cells, the second and third placed between the two ulnar veins, the first between apex of radial and base of second apical cells; costa and radial vein piceous and punctured; destitute of a transverse venule between two ulnar veins, near the base. Wings with four apical cells. Legs simple (Goding 1903).

Day (1999) provided a comprehensive redescription of the genus.
