Length of male 4.5-6.7. mm, of female 5.6-7.2 mm. 
Head varying from moderately to well produced, anterior margin broadly 
rounded in dorsal view, median length of crown greatly variable compared to 
(from slightly more than one-half, to equal to) interocular width, and varying 
from one-third to six-tenths transocular width, without a carina at transition 
from crown to face, ocelli located on or behind (S. chanchama, n. sp.) a line be- 
tween anterior eye angles, each ocellus usually slightly closer to adjacent an- 
terior eye angle than to median line of crown; crown convex, with or without 
a transverse concavity before ocelli, without a median fovea and usually 
without sculpturing (punctate in S. mesolinea (DeLong and Currie)), without 
setae, lateral clypeal sutures extending onto crown and attaining ocelli 
(exception: S. infula (Melichar)); antennal ledges not protuberant, in lateral 
view with anterior margins oblique and convex; face nearly always without a 
vertical lenticular sclerite bordering lateral clypeal suture on each side, cly- 
peus not or only slightly flattened medially, muscle impressions not very dis- 
tinct (exception: mesolinea), transclypeal suture complete or obsolete at middle, 
clypellus not produced, its contour continuing profile of clypeus. 
Thorax with pronotal width equal to, greater, or less than transocular 
width of head, lateral margins slightly convergent anteriorly, dorsopleural 
carinae complete, posterior margin usually slightly concave, disk without 
sculpturing (exception: mesolinea which has transverse rugae) or pubescence; 
scutellum not transversely striate behind transverse sulcus. Forewing with 
membrane present, varying interspecifically in extent, with three closed ante- 
apical cells, of which the bases of the outer two are slightly more proximal 
than base of inner anteapical cell, with four apical cells, the base of the fourth 
more proximal than base of third, without an anteapical plexus of veins; fore- 
wings of female in rest position exceeding apex of ovipositor. Hindleg with 
femoral setal formula 2:1:1, length of first tarsomere greater than combined 
length of two more distal tarsomeres, and with two parallel rows of small 
setae on plantar surface. 
Male genitalia: Pygofer moderately produced, apex varying interspecifically 
from narrowly to broadly rounded (subtruncate in S. praevia (Melichar)), with 
numerous macrosetae on posterior half, the setiferous area extending an- 
teriorly or anteroventrally in some species, pygofer processes not differentially 
sclerotized when present (exception: praevia). Plates slender and triangular, 
usually not extending as far posteriorly as pygofer apex, with few macrosetae 
in longitudinal row. Style usually not extending posteriorly nearly as far as 
apex of connective, truncate apically (exception: infula), with preapical lobe
