than transocular width of crown, lateral margins divergent posteriorly; fore- 
wing with membrane including only inner apical cell; middle anteapical cell 
usually, and inner anteapical cell occasionally open basally; hind femoral setal 
formula 2:0:0 or 2:1:0. Male with pygofer broadly rounded posteriorly, with 
numerous regularly dispersed macrosetae on ventral portion of posterior half, 
pygofer process arising dorsally and anteapically, short, extending posteriorly; 
style extending slightly further posteriorly than apex of connective, curved 
abruptly laterally at apex and gradually tapered in apical portion, without 
preapical lobe; aedeagus with pair of processes arising ventrally near base, 
curved gradually posteriorly and dorsally, each widened anteapically, shaft 
concave on both anterior and posterior margins. Female abdominal sternum 
VII very slightly concave on posterior margin. Other structural characters as 
in generic description. 
Ground color of crown, pronotum and scutellum, yellow, an arcuate band 
at apex of crown, a lineal marginal marking astride suture before eye, an 
irregular area surrounding each ocellus, a spot behind each ocellus on 
posterior margin of head, lateral pronotal margins and a pair of spots on an- 
terior portion of disk, three angular spots on base and two anteapical lateral 
spots on scutellum, black; forewings yellowish-orange, veins conspicuously 
paler, face with a broad transverse line across transclypeal suture, continuing 
more narrowly across genae and expanding at posterior genal margin, and a 
median longitudinal clypellar stripe, black. 
Holotype male, Misiones, Argentina and a number of additional specimens 
of both sexes from Misiones and Corriente, Argentina in Museo de la Plata. A 
series from Santa Catharina, Brazil (NCS). Two specimens Rio Grande do 
Sul (BM). 
S. dimidiata, n. sp., is related to S. grandis (Walker) from which it can be dis- 
tinguished by its lack of longitudinal markings over crown and pronotum and 
by its abruptly curved styles.

Type-species: Tettigonia ruficauda Walker. 
Length of male 5.8-7.5 mm, of female 6.4-8.4 mm. 
Head very slightly produced, with anterior margin broadly rounded in dor- 
sal view, median length of crown varying from slightly less than one-half to 
almost six-tenths interocular width and from slightly more than one-fourth to 
slightly more than one-third transocular width, without a carina at transition 
from crown to face, ocelli located on or slightly behind a line between anterior 
eye angles, each ocellus approximately equidistant from median line and adja- 
cent anterior eye angle, crown without a concavity across ocelli, slightly con- | 
vex on each side of a shallow median longitudinal depression that extends 
forward slightly beyond ocelli, lateral clypeal sutures extending onto crown 
and attaining ocelli; antennal ledges not protuberant, in lateral view with an- 
terior margins oblique and convex; face without a vertical lenticular sclerite 
bordering lateral clypeal suture on each side below eye, clypeus flattened
