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. angularis. Ground colour grey-green to green. Tegminal granules not darkened at tip. Apex of clavus usually with small brownish spot. Vertex with evenly rounded front margin. Tegmen with sutural angle produced so that apical margin slightly concave. Male pygofer process elongate, narrow, extending to 2/3 length of paramere. Paramere rectangular with prominent triangular process forming recurved hook continuous with apical curve of paramere. Female third valvulae broadly triangular with pilose area ventral. Second valvulae gap U-shaped, about as wide as deep (Fletcher 1985).
