Introduction

A relatively small genus although there appear to be a number of species in collections representing undescribed species. The relationships between this genus, Hypsiphanta Jacobi and Euryphantia Kirkaldy need to be investigated. Euphanta includes some relatively common medium sized green triangular flatid planthoppers. The species of this genus can be differentiated from those of Siphanta Stål by the vertex which is flat in Siphanta but bilaterally convex in Euphanta. From Colgar Kirkaldy, which also have the head produced forwards to form a cone, they can be differentiated by having the anterior margin of the vertex carinate while in Colgar there is no marginal carina.

Diagnosis

Mit der Gattung Siphanta Stål nahe verwandt. Unterscheidet sich von dieser insbesondere dadurch, dass bloss der spitzwinkelig vorgezogene Scheitel oben flach ist, während das Pronotum und das Schildchen gewölbt sind. Scheitel, Pronotum und Schildchen sind mit einem deutlichen Mittelkiel versehen, auf dem Schildchen befinden sich überdies noch zwei Seitenkiele. Stirne länger als breit, mit drei scharfen Kielen, welche sich an der Stirnspitze miteinander verbinden. Fühler sehr kurz. Ocellen vorhanden. Deckflügel wie bei Siphanta, der Verlauf der Nerven jedoch abweichend. Die Costalzelle stets geschlossen. Hinterschienen mit einem Dorne (Melichar 1902).

Head triangularly produced. Frons separated from vertex by carinate margin; flat to slightly convex, clearly tricarinate. Vertex flat, with median longitudinal carina. Pronotum and mesonotum convex, longitudinally carinate. Tegmen triangular, apical margin straight between rounded angles. Cu simple. Subapical lines absent. Costal cell wider than costal membrane. Hind tibia with one spine on external margin (Fletcher 1988).
