  Type data:

   Holotype ANIC 9453 ♂ (coll.: 12.viii.1976, I.F.B. Common), 150 km SE by E Broome, Western Australia.

Introduction

The narrow, tegmen gives this species a similar appearance to S. lucindae Kirkaldy and S. granulata Kirkaldy but it can be distinguished from both by the shape of the male paramere. The male genitalia indicates that it has a close relationship with S. roseicincta (Walker) and it was placed in the roseicincta group by Fletcher (1985) who also indicated that some slight variation in the male genitalia can be found in the species. The species is found in inland areas of the continent and is quite widespread. The type series includes specimens from Western Australia, Northern Territory, South Australia and near Mt Isa in western Queensland.

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. angustata . Pale green with yellow veins. Costal margin of tegmen pale cream to apex of costal cell. Outer claval vein not red. Head with frons wider than long with lateral carinae indicated at apex. Tegmen with numerous crossveins; apical margin shallowly convex between angles; first branch of M1+2 just beyond 2/5 length of tegmen. Male pygofer process short, triangular, pointed, sometimes curved ventrally. Paramere rectangular with narrow pointed process at very apex. Dorsal margin continued posteriorly beyond process to form "shoulder" against which apex of anal tube normally fits. Female third valvulae bilaterally flattened apically with pilose area on inner surfaces. Second valvulae gap wider than deep, U- or V- shaped (Fletcher 1985).
