   Platymetopius hyalinus Osborn, 1900 by original designation.

Introduction

This small genus contains three species, one in Japan, one in Nepal and the third has been introduced to the Nearctic and Palaearctic regions and is represented in the Australian fauna. The Japanese maple leafhopper, J. hyalinus (Osborn) is reasonably distinctive although it is superficially similar to Dryadomorpha pallida Kirkaldy.

Diagnosis

A narrow headed form with a long acute vertex in the female, a short but slightly acute one in the male, a broad pronotum strongly constricted and advanced between the eyes, a large scutellum, broad elytra with simple venation and no reticulations, a single cross nervure between the sectors. Three large cells occupy the apical portion of the elytra, the first apical forming a long narrow cell against the costa bounded by two short veinlets at right angles to costa. The posterior veinlet is in line with the apex of the outer anteapical, the second apical therefore trianguilar as in the fifth. Face in profile acutely angled with vertex, front narrow, in the female produced in a triangle with the vertex. A hair-like dark line just below the margin (Ball 1931).
