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. galeata. Costal margin of tegmen sometimes narrowly red from near base but tegmen otherwise lacking red. Tegminal granules dark at tip, particularly those near apex of tegmen. Head with frons strongly convex in basal portion; vertex triangularly produced, not evenly rounded anteriorly. Tegmen with apical angle nearly rightangled; apical margin straight to concave; sutural angle produced dorsally to acute point. Male pygofer with blunt triangular process. Paramere narrow, with bluntly pointed process about equal in length to pygofer process. Female third valvulae triangular with pilose area ventral. Second valvulae gap widely U-shaped, shallow, about twice as wide at tips of valvulae as deep (Fletcher 1985).
