_ Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae complete, posterior 
margin very slightly concave, disk not or only obscurely rugulose, not pubes- 
cent; scutellum not striate behind transverse sulcus. Forewing with membrane 
including all of apical cells except base of third, and extending forward along 
costal margin to bases of anteapical cells, veins dark, distinct, with three an- 
teapical cells all of which are closed basally, with four apical cells of which 
third is petiolate and base of fourth is located more proximally than base of 
third, without an anteapical plexus of veins, texture coriaceous and without 
sculpturing. Hindleg with femoral setal formula 2:1:1, length of first tar- 
somere greater than combined length of two more distal tarsomeres and with 
two parallel longitudinal rows of small setae on plantar surface. 
Male genitalia: Pygofer moderately produced, posterior margin convex, 
macrosetae variable in size, irregularly spaced, extending in a broad mul- 
tiseriate group parallel to posteroventral margin to dorsal margin, pygofer 
process as in Scopogonalia, new genus (see below). Plates short, narrowly 
triangular, not extending nearly as far posteriorly as pygofer apex. Style not 
extending posteriorly nearly as far as apex of connective, without a preapical 
lobe. Connective a longitudinal bar, widened at base. Aedeagus broad, direc- 
ted ventrad, with a pair of very short apical processes. Paraphysis unpaired, 
articulated both with apex of connective and with base of aedeagus, without 
processes. 
Female abdominal sternum VII strongly produced and acute apically. 
Ovipositor with second valvulae toothed on apical three-fourths behind basal 
curvature, the teeth slanting except near apex, and bearing minute secondary 
denticles, anteapical dorsal and ventral denticles present. Pygofer strongly 
produced and with numerous macrosetae in an irregular group parallel to 
posteroventral margin. 
Plerogonalia, new genus, is known only from the type-species which has the 
forewings and the posterior portion of the pronotum deep green, the anterior por- 
tion of the pronotum and the scutellum buff, and the crown yellowish brown with 
an apical spot. 
Plerogonalia is known only from Peru and Bolivia. It is close to Scopogonalia, 
from which it differs in the larger size of its specimens, its unpaired 
paraphysis, and in the anteapical cells which are closed basally. Plerogonalta is 
also closely related to Rotigonalia, new genus, in both male and female genital 
structures, but Rotigonalia has paired paraphyses in the male, and a less 
produced pygofer and abdominal sternum VII in the female. 
I have studied the lectotypes of Tettigoniella rudicula Jacobi and T. facetula 
Jacobi.
