Type-species: Tettigonia german Signoret (1853b:359). 
Length of male 8.8 mm, of female 8.8-9.1 mm. 
Head moderately produced with anterior margin broadly rounded in dor- 
sal view, median length of crown varying from slightly less than four-tenths to 
slightly more than four-tenths interocular width and from one-fourth to 
slightly more than one-fourth transocular width, without a carina at transition 
from crown to face, ocelli located before a line between anterior eye angles, 
each closer to median line of crown than to adjacent anterior eye angle, sur- 
face of crown convex and coarsely and heavily punctate, lateral clypeal 
sutures extending onto crown and attaining ocelli; antennal ledges not pro- 
tuberant, in lateral view with anterior margins oblique and slightly concave; 
clypeus convex, disk coarsely and densely punctate, muscle impressions dis- 
tinct, transclypeal suture obsolete, clypellus greatly flattened, its contour not a 
continuation of profile of clypeus. 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae complete, posterior margin shallowly 
concave, surface coarsely and irregularly rugose; scutellum coarsely trans- 
versely rugose on basal two-thirds. Forewing with only inner apical cell mem- 
branous; veins not very distinct, with three closed anteapical cells of which all 
bases are proximal to claval apex, 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, with two parallel rows of small setae on 
plantar surface. 
Male pygofer moderately produced, broadly rounded at apex, with a num- 
ber of macrosetae on posterior two-thirds, pygofer processes absent. Plates 
narrowly triangular with apices narrowly rounded, extending posteriorly 
almost as far as pygofer apex, with multiseriate small setae. Style short, 
narrowly rounded apically, with a preapical lobe, extending posteriorly ap- 
proximately as far as apex of connective. Connective narrowly T-shaped, fused 
at its apex with base of paraphyses. Aedeagus extending posterodorsally, 
broad in ventral view, with a pair of flangelike apical processes; basal 
apodemes very short. Paraphyses short-stalked, biramous, each ramus broad 
and with an apical very narrow process. 
Female abdominal sternum VII not produced, posterior margin shallowly 
concave. Ovipositor with second valvula bearing numerous teeth on strongly 
convex dorsal margin beyond the basal curvature, the primaries triangular 
near base, rectangular through remainder of valvula and each bearing 
numerous minute secondary denticles, with denticles on anteapical dorsal and 
posteroventral margins. 
Trachygonalia, new genus, is known only from the type-species, 7. germari 
(Signoret) from southern Brazil. Specimens are black with an arcuate trans- 
verse pale band across the wings including the scutellar apex and a similar
