Diagnosis

granulicollis Group. Head short, frons longer than widest part which is level with antennae. Vertex with apical margin evenly rounded or obtusely angulate. Apical and basal margins of vertex more or less parallel. Tegmen with apical and sutural angles rounded. Costal margin convex throughout, more strongly so on basal half, so that widest part of tegmen at about midlength. Clavus long, extending nearly to sutural angle, so branching of M1+2 well basal of claval apex. Colour green, fading to yellow or orange in dried specimens. Apex of head, fore- and mid-tibiae externally and usually tarsi, red. Tegmen usually with red border from apex of costal cell around apical margin and claval margin to apex of clavus, this border interrupted by green vein endings. Outer claval vein usually red. Tegminal granules black.
S. tasmanica. Abdomen of male dark brown. Male pygofer with dorsolateral corner triangularly prominent posteriorly, process not clearly differentiated. Paramere narrow with prominent blunt process. Lateral hook from conjunctiva smaller than in other species in the group. Female third valvulae blunt at apex with pilose area ventral. Second valvulae gap U-shaped, inner margins of valvulae parallel for most of length (Fletcher 1985).
