These genera are grouped into five subtribes: Terpnosiina Kato, Leptopsaltriina Moulton, Dundubiina Matsumura, Cosmopsaltriina Kato and Tosenina Amyot & Serville. Only the subtribe Cosmopsaltriina is relevant to the Australian fauna, see below.

Diagnosis. Head with distance between supra-antennal plate and eye about equal to length of antennal plate. Postclypeus shape in transverse cross-section rounded; postclypeal ridges lacking transverse grooves towards distal ends. Pronotal collar with lateral margin weakly ampliate; lateral tooth present. Fore wing pterostigma present; veins C and R+Sc close together; vein RA 1 aligned closely with subcosta (Sc) for its length. Hind wing with anal lobe narrow and vein 3A straight, short, adjacent to wing margin. Fore leg femoral primary spine erect. Meracanthus gradually tapering to a point, triangular or nearly so. Male opercula very long, reaching far beyond tympanal cavity to cover some two thirds length of abdomen, clearly separated. Male abdominal tergites with sides straight or convex in crosssection; tergites 2 and 3 similar in size to tergites 4–7; epipleurites reflexed to ventral surface, epipleurite 4, and sometimes also others, strongly kinked inwards in a V-shape. Timbals extend below wing bases. Timbal covers flat; fully rounded dorsally, extending to metathorax, tightly closing the timbal cavity or nearly so; lower margin extending vertically from auditory capsule before turning anteriorly. Pygofer upper lobe absent; basal lobe moderately to well developed; distal shoulder distally extended into pointed, and often apically up-turned, lobe (except in subtribe Dundubiina); dorsal beak present, either as a flap on “hinge” tissue or, in Cosmopsaltriina a part of chitinized pygofer. Uncus digitate or basically tubular, long, dominant and often deeply divided into lateral lobes; claspers absent in subtribe Dundubiina, present in subtribe Cosmopsaltriina.Aedeagus with basal portion of basal plate directed forwards away from thecal shaft; ventral rib completely fused with basal plate; theca recurved basally through some 180° in subtribe Dundubiina, straight or curved in a gentle arc in subtribe Cosmopsaltriina; pseudoparameres absent; subapical cerci absent. Male reproductive system with accessory glands long. Female reproductive system with length of accessory glands of common oviduct unknown.

Distinguishing characters. Pronotal collar with lateral tooth. Hind wing with anal lobe narrow and vein 3A straight, short, adjacent to wing margin. Male opercula very long, reaching far beyond tympanal cavity to cover some two thirds length of abdomen, clearly separated; tergites 2 and 3 much enlarged, 2+3 usually accounting for approximately half abdominal length. Timbal covers fully rounded dorsally, extending to metathorax, tightly closing the timbal cavity or nearly so. Pygofer dorsal beak present as a flap on “hinge” membrane.

Discussion. Lee & Hayashi (2003) combine the Dundubiini and Cicadini. They retain the name Dundubiini, placing Cicadini in synonymy although strictly speaking Cicadini has priority (see discussion under Dundubiini p. 391 above). I am tentatively retaining the Dundubiini in anticipation of an overview of these two tribes.

Primary attributes of earlier authors that are retained here include the presence of a lateral tooth on the pronotal collar and the characteristic elongation of the male opercula. Of the subtribes currently recognized only the Cosmopsaltriina is represented in Australia.
