Type-species: Tettigonia flavomaculata Blanchard. 
Length of male 5.3-5.7 mm, of female 6.0-6.2 mm. 
Head moderately produced, median length of crown varying from two- 
thirds to slightly more than seven-tenths interocular width and between four- 
and five-tenths transocular width, anterior margin narrowly rounded in dorsal 
view, without a carina at transition from crown to face, ocelli located before a 
line between anterior eye angles, each closer to median line than to adjacent 
anterior eye angle, crown without a transverse concavity or a median fovea, 
surface finely and regularly punctate, lateral clypeal sutures extending onto 
crown, but not extending to or near ocelli; antennal ledges not protuberant, in 
lateral view with anterior margins convex; clypeus convex, muscle impres- 
sions not distinct, transclypeal suture obsolete at middle, clypellus not 
produced, the contour of its apical portion more nearly horizontal than profile 
of remainder of face. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae complete, posterior 
margin concave, disk transversely rugose, not pubescent; scutellum trans- 
versely rugose in its posterior half. Forewing with membrane including inner 
three apical cells, veins not elevated, indistinct except at apex, with two an- 
teapical cells of which the outermost is open basally, with four apical cells, 
without an anteapical plexus of veins, texture coriaceous except a broad trans- 
lucent area bordering costal margin; forewings of female in rest position ex- 
ceeding apex of ovipositor. Hindwing with marginal vein at wing apex. Hind- 
leg 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 weakly produced, with apical margin truncate, tex- 
ture membranous in middle of disk, completely without setae. Plates elongate, 
triangular, fused basally, extending posteriorly beyond apex of pygofer, 
without setae. Style extending posteriorly beyond apex of connective, acute 
apically, without preapical lobe, with ventral denticles through more than 
apical half of length. Connective narrowly Y-shaped. Aedeagus simple, fused 
with apex of connective, shaft tapering, curved dorsally and anteriorly, 
without processes. 
Female abdominal sternum VII not strongly produced, posterior margin 
with a deep narrow median notch. Genital chamber without sclerites. Ovi- 
positor with second valvulae expanded beyond basal curvature, with widely 
spaced triangular teeth at base and larger, quadrate, sloping primary teeth at 
apical part of expanded portion, each bearing minute secondary denticles, 
with numerous anteapical dorsal denticles.
