Introduction

The green planthopper is one of the most familiar planthoppers in Australia and is distributed along the eastern coast and adjacent slopes and ranges from the wet tropics of North Queensland to Tasmania as well as in the SW of Western Australia and two sites in South Australia. It is also found on Norfolk Island and has been introduced to New Zealand, Hawaii, the west coast of North America and South Africa. It is highly adaptable, as its distribution indicates, and is known from a wide range of native and exotic plant species (Fletcher 1985: 4). Its life history was described by Myers (1922) in New Zealand and Muir & Kershaw (1912) described its embryonic development in Hawaii. This is the nominal species of the acuta group which includes 16 species of Siphanta (Fletcher 1985: 7).

Diagnosis

acuta Group. Head produced medially in front of eyes so that frons apically convex and vertex at least half as long as wide. Frons with three short longitudinal indicated near apex. Tegmen triangular with apical angle rounded and sutural angle right-angled or acutely produced dorsally. M1+2 branched level with apex of clavus. Coloration green or grey-green, often fading to yellow in dried specimens. Males usually duller than females. Apex of head, apices of fore- and mid-tibiae and all tarsi and often lateral angles of frons marked with red. Tegmen with minute granulations in all cells leaving bare circular spot in centre of each cell. Costal margin pallid, then narrowly red around apical margin and claval margin to apex of clavus. Individuals may lack all red coloration and show other variation.
S. acuta Pale olive green to green. Tegminal granules concolorous with ground colour of tegmen. Male sometimes with small infuscation at first forking of M1+2. Head with frontal carinae sometimes obsolescent; anterior margin of vertex evenly rounded. Tegmen with prominence of sutural angle somewhat variable but always forming acute angle. Male pygofer with posterodorsal corner extended to form short blunt point. Paramere rounded apically with broad, obliquely truncate process perpendicular to dorsal margin of paramere and mounted at approximate midlength. Female ventral valves broadly triangular with pilose area ventral. Second valvulae gap narrowly U-shaped (Fletcher 1985).
