Introduction

This genus is distributed across the Oriental region from India and Pakistan to the Philippines with species also known from Africa (Webb 1976) and Japan. Two species have been introduced to Australia where they are pests of mango, Mangifera indica L. (Anacardiaceae). Comparison of the two species was provided by Fletcher & Dangerfield (2002).
