Introduction

This monotypic genus contains one of the world's worst pests of maize, Peregrinus maidis (Ashmead), the maize planthopper which transmits Maize Stripe Tenuivirus, Maize Mosaic Virus (= Maize Mosaic Rhabdovirus), Sorghum Stripe Virus and Maize Mosaic Nucleorhabdovirus in SE Asia and the Pacific. The species has a pantropical distribution.

Diagnosis

This genus agrees with Dicranotropis in the forking of the front, in the antennae, in the non-contiguity of the frontal and genal keels apically, in the ocelli not nearly touching the lateral keel of the frons, but being situated close to, or touching, the eyes, and in the form of the tibial spur. It differs chiefly in the tegminal and alar venation in the macropterous forms, and in the lateral keels of the pronotum which practically reach the hind margin and curve inwards here rather than outwards. The second and third apical veins have a common stalk, the latter being reforked. The pygophor has no spines or hooks on the ventral margin in the males, nor on the ventral wall of the anal tube (Kirkaldy 1907)
