Cicadas
Macrotristria Stål, 1870
Type species: Cicada angularis Germar, 1834
Fauna Portal Genus Number: 652
(after Moulds 2012): Medium to large cicadas. The broad pronotal collar (nearly equal to diameter of eyes, or a little more) with lateral margins greatly reduced is unique to Macrotristria. Also characteristic is a distinct rounded lobe to the anterior lateral margin of the pronotal collar. The male opercula closely follow the rim of the tympanal cavity and the timbal covers never tightly close off the timbal cavity. The male genitalia lack unique characters; the theca has either one or two subapical cerci; the pygofer basal lobes, while moderately developed in most species, are very elongate in M. angularis and the uncus, although finger-like, shows much variety in form between species.
