Introduction

This genus comprises largish species of Erythroneurini characterised by the presence of circular pits on the expansive pronotum. The Australian fauna includes at least 20 undescribed species with two additional species known in Papua New Guinea. The distribution provided here includes the undescribed species.

Diagnosis

Elongate; vertex more than twice as wide as long dorsally, anteriorly rounded, bent over in front and extending ventrally about as far as antennal scrobes; demarcation from frons not very distinct; posteriorly above tumidly raised, posterior margin much more so than the apical margin of pronotum. Head distinctly wider than pronotum anteriorly. Clypeus oval, about as wide as frons apically. Pronotum large, reticulate, almost as long as wide, about two and a half times as long as vertex dorsally, strongly arched anteriorly, lateral margins long, not carinate, posterior margin subtruncate. Tegmina with two discoidal (I subapical) and 4 apicals. \\'ings without submarginal vein (Kirkaldy 1906).

Body large and robust, upper part of face, pronotum and scutum distinctly punctate, but pits much sparser than those in Musbrnoia Dworakowska, 1972 and Variolosa Cao & Zhang, 2013. Head broad, as wide as or slightly narrower than pronotum, crown fore margin subparallel to hind margin. Ocelli consisting of elongated, crescent-shaped vestiges continuous with lateral frontal sutures. Face strongly convex in profile, anteclypeus ovoid, lorum large. Forewing with first and third apical cell broad, second apical cell narrowest, fourth apical cell almost as long as third, AA and AP present. Hind wing venation usual for Erythroneurini, RA vein present. Abdomen with numerous pits, 2S abdominal apodemes very small in examined species. Without anal tube appendage. Pygofer well sclerotized, with some rounded membranous areas of different sizes, setosity rudimentary; without dorsal and ventral appendages. Subgenital plate surpassing hind margin of pygofer side, base fused with sternite IX, broadened subbasally and narrowing towards apex, with about 2 macrosetae subbasally near outer margin, withsome rigid setae on distal half of ventral side, without marginal microsetae. Style with apical part club-like, basal part elongated, preapical lobe shifted apically, well protruded. Connective U-shaped, manubrium short but broad, central lobe absent. Aedeagal shaft tubular, usually with asymmetric processes; preatrium short (Cao et al. 2019)
