Introduction

This is a common and widespread species which occurs in two colour forms, specimens from Cape Leeuwin in Western Australia having the costal margin of the tegmen greenish rather than red. Some variation in the male genitalia was found by Fletcher (1985) which might justify species separation but the variation was continuous from Western Australia to eastern Australia. The holotype of Parasalurnis insularis is labelled "Bandin I." and this was interpreted by Fletcher (1985) as Baudin Island. In the original description, however, Distant (1910) used the name "Baudin Island" and indicated that it was in NW Australia which establishes the locality in the Northern Kimberley rather than the other Baudin Island which is in Shark Bay, Western Australia.

Diagnosis

roseicincta Group. Head short, vertex no more than ½ as long as wide at base. Apical margin of vertex roundly or angularly produced slightly. Frons wider than long or as wide as long with strong median longitudinal carina but lateral carinae obsolete or indicated at very apex only. Tegmen narrow with apical angle rounded and sutural angle rounded or obtusely angulate, never produced. M1+2 branched at about middle of tegmen, well before apex of clavus. Green, fading to yellow or orange in dried specimens. Frons dark brown in most species. Apex of head, carinae of frons, outer claval vein, fore- and mid-tibiae and all tarsi usually marked with red. Tegminal granules black at tip. Margin of tegmen except base of costal margin and claval margin to apex of clavus marked with red.
S. roseicincta. Green, fading to orange in dried specimens. Frons brown with red at base and along carinae. Vertex red with pale granulations. Thorax with broad red stripe along midline, sometimes extending laterally on pronotum. Tegmen with orange crossveins. Costal margin may be red from base or only beyond apex of costal cell. Outer claval vein, and usually outer claval cell and most of median claval cell, red. Red marking may be very much reduced or absent on all parts except granules around base of outer claval cell and apex of head. Head with lateral carinae of frons obsolete; vertex slightly concave on disc; apical margin of vertex angularly produced so vertex slightly longer in midline than against eyes. Tegmen with costal margin convex throughout, male pygofer with large process, which may be apically rounded or pointed. Paramere with strong pointed process. Female third valvulae elongate triangular with pilose area ventral. Second valvulae gap widely U-shaped as wide as deep (Fletcher 1985).
