  Type data:

   Holotype ANIC 9452 ♂ (coll.: 16.xi.1967, Kerrs Light Trap), Kununurra, Western Australia.

Introduction

This species, only known from northern Western Australia, has marked similarities with S. fusca Fletcher from which it can be easily differentiated by the restriction of the brown colour typical of S. fusca to the outer claval cell of S. occidentalis. Fletcher (1985) included both of these species in the anomala group.

Diagnosis

Head dark brown, speckled with red and black. Thorax orange (probably green in life), dark brown dorsally, speckled with red laterally. Tegmen orange (probably green in life), finely speckled with red, particularly on crossveins. Granules dark at tip (more so in some specimens than in others). Costal margin from apex of costal cell, apical margin and claval margin to apex of clavus red, broken at vein endings. Outer claval cell reddish brown or brown. Frons with lateral margins rounded, widest at level of antennae; apex of frons with obscure median longitudinal carina and faint lateral carinae; vertex with apical margin evenly rounded. Tegmen with costal margin strongly convex to apex of costal cell, thence straight or slightly concave to rounded apical angle; sutural angle rounded; M1+2 branched just proximal to level of apex of clavus. Male pygofer with short prominence from dorsolateral corner. Paramere triangular with short recurved process. Female third valvulae short, triangular, with pilose area lateroventral. Second valvulae gap widely V-shaped (Fletcher 1985).
