Introduction

Species of Dardus are all short squat insects with dark coloured tegmina, frequently with a white spot on the tegmen and red venter. The most common and widespread is D. abbreviatus which is found on wattles. The genus is in need of revision since most of the species are unidentifiable without reference to the original type material. There are six species currently recognised in the genus, all endemic to Australia.

Corpus breve, ovale. Caput latissimum, cum oculis thoraci aequilatum, vertice transverso, brevi; fronte latissima, utrimque valde angulata, apice supra labrum sinuata, hoc unicarinato. Antennae oculus et frontis latera valde superantes, articulo tertio praecedentibus fere sextuplo longiore, apicem versus subangustiore. Thorax cum scutello longitudine latior, illo hoc dimidio breviore. Tegmina abdomen nonnihil superantia, ovalia, longitrorsum furcato-nervosa, pone medium nervis transversis reticulata. Abdomen breve, reliquo corporo brevius. Pedes antici compressi, dilatati, tibiis posticis spinis 2 vel 3 armatis. Genus Eurybrachydi affine, differt statura breviore, antennis praesertim articulo tertio longioribus, fronte apice sinuata, genis ante oculos angustissimis tegminibusque pone medium minus dense et minus regulariter reticulatis (Stål 1859)
