FiGguRE 136 
Type-species: Tettigonia sirena Stal. 
Length 8.0-9.1 mm. 
Head moderately produced with anterior margin broadly rounded in dorsal 
view, median length of crown varying from slightly less than six-tenths to 
slightly less than two-thirds interocular width and from one-third to four- 
tenths transocular width, without a carina at transition from crown to face, 
ocelli located on or almost on a line between anterior eye angles, each ap- 
proximately equidistant from median line of crown and adjacent anterior eye 
angle, crown very shallowly concave before ocelli, without a median fovea, 
surface of crown without sculpturing or setae, lateral clypeal sutures ex- 
tending onto crown and attaining ocelli; antennal ledges not protuberant, in 
lateral view with their anterior margins oblique and slightly convex; clypeus 
convex, muscle impressions distinct, clypellus with contour continuing profile 
of clypeus. 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae usually complete, posterior margin 
shallowly concave, disk transversely rugose, not pubescent; scutellum not 
rugose behind transverse sulcus. Forewing with membrane including at least 
inner three apical cells, veins distinct in color except crossveins in some 
specimens, with three anteapical cells of which the base of innermost is op- 
posite claval apex and bases of two outermost are more proximal; forewings of 
female in rest position exceeding apex of ovipositor. Hindleg with femoral 
setal formula 2:1:1; length of first tarsomere equal to, or greater than com- 
bined length of two more distal tarsomeres and with two parallel rows of 
small setae on plantar surface. 
Male genitalia: Pygofer not strongly produced posteriorly, narrowly round- 
ed posterodorsally, with few macrosetae of varied sizes in irregular pattern on 
apical half; pygofer processes absent. Plates, triangular, slender, tapering 
gradually, extending posteriorly as far as or farther than pygofer apex, each 
with uniseriate macrosetae. Style extending posteriorly farther than apex of 
connective. Aedeagus with shaft extending posterodorsally, in lateral view
