CICADELLINAE: PART 2, NEW WORLD CICADELLINI 1037 
141. TLAGONALIA, New GENus 
FiGuRE 842 
Type-species: Tettigonia nigroguttata Signoret (1855d:772). 
Length 8.0-8.8 mm. 
Head well produced, median length of crown varying from slightly more 
than one-half to approximately seven-tenths interocular width, and from 
slightly more than one-third to more than four-tenths transocular width, with- 
out a carina at transition from crown to face, ocelli located on a line between 
anterior eye angles, each ocellus slightly closer to adjacent anterior eye angle 
than to median line of crown, crown with a transverse concavity across ocelli, 
without a median fovea and without sculpturing or setae, lateral clypeal 
sutures extending onto crown and attaining ocelli; antennal ledges not pro- 
tuberant, in lateral view with anterior margins oblique and convex; face with- 
out a vertical lenticular sclerite bordering lateral clypeal suture on each side 
below eye, muscle impressions distinct or not, transclypeal suture obscure 
medially, clypellus with profile of its upper portion continuing contour of 
clypeus, its lower portion slightly more nearly horizontal. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae complete, posterior 
margin concave, disk of pronotum without sculpturing; scutellum not trans- 
versely striate behind transverse sulcus. Forewing with only inner portion of 
inner apical cell membranous, veins not elevated, not very distinct, with three 
closed anteapical cells of which base of innermost is opposite claval apex, 
bases of two outermost more proximal than claval apex, with four apical cells 
and the base of the fourth obscure, not or only slightly more proximal than 
base of third, without supernumerary crossveins in anteapical cells; forewings 
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 plan- 
tar surface. 
Male genitalia: Pygofer moderately produced, apex broadly convex, with a 
number of macrosetae near posterior and posteroventral margin, mixed with a 
few small microsetae. Pygofer processes absent. Plates triangular, not ex- 
tending posteriorly as far as pygofer apex, with macrosetae uniseriate or 
nearly so. Style extending posteriorly as far as or slightly beyond connective; 
apex truncate, with an angulate lateral projection. Connective somewhat Y- 
shaped. Aedeagus symmetrical, basal apodemes long, shaft bisinuate, apex 
with a slight lateral expansion on each side. Paraphyses short, U-shaped. 
Female abdominal sternum VII moderately produced, posterior margin 
shallowly concave on each side of a small median lobe. Ovipositor with 
second valvulae each toothed in most of portion beyond basal curvature, the 
teeth subquadrate, widely spaced near base, much closer near apex, apex dor- 
sal to axis and acute. Pygofer rounded, with macrosetae in a broad diagonal 
group parallel to posteroventral margin. 
Tlagonalia, new genus, is known only from the type-species, 7. nigroguttata 
(Signoret) which is pale orange marked with seven black spots anteriorly.
