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 carinae indicated near apex. Tegmen usually 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. This colour pattern is fairly stable throughout the group (variation is noted below) but individuals may lack all red coloration or show other individual variation.
S. glauca. Tegminal granules dark at tips. Frons with strong longitudinal carinae over basal half; vertex with front margin evenly rounded anteriorly. Tegmen triangular with apical angle roundly rightangled or slightly obtuse and sutural angle produced dorsally to a point. Male pygofer without process, dorsolateral corner rounded. Paramere parallel-sided with strongly pointed process. Female third valvulae broadly triangular with pilose area ventral. Second valvulae gap widely U-shaped. Apex of anal tube entire or very slightly emarginate (Fletcher 1985).
