Rhopalogonia Melichar, 1926a:341. Type-species: Tettigonia scita Walker, 1851b:753, by 
subsequent designation of China, 1938d:183. 
Length of male 10.0-10.6 mm, of female 10.5-10.7 mm. 
Head slightly produced, median length of crown from slightly less than one- 
half to slightly greater than one-half interocular width and from slightly less 
than three-tenths to slightly more than four-tenths transocular width, anterior 
margin broadly rounded in dorsal view, without a carina at transition from 
crown to face, ocelli located on or slightly before a line between anterior eye 
angles, each 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 protuberant, in lateral view 
with anterior margins oblique and convex; clypeus convex, muscle impressions 
distinct, face without conspicuous pubescence, transclypeal suture interrupted, 
clypellus not strongly produced, its contour continuing profile of clypeus. 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae not quite attaining posterior eye 
margin, disk transversely rugose, not pubescent; scutellum not striate behind 
transverse sulcus. Forewing with membrane usually not well delimited, veins 
distinct, with four apical cells, the base of fourth more proximal than base of 
third, without an anteapical plexus of veins, texture translucent and without 
sculpturing; 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 second and third tarsomeres and with two parallel 
rows of small setae on plantar surface. 
Male genitalia: Pygofer slender and moderately produced, posterior margin 
broadly convex with a group of numerous macrosetae on apical third and ex- 
tending anterobasally parallel to posteroventral margin. Plates elongate, slen- 
der, extending posteriorly much beyond pygofer apex, with sparse multiseriate 
small macrosetae, apices acute. Style extending much farther posteriorly than 
apex of connective, without a preapical lobe, acute apically. Connective short 
Y-shaped, keeled. Aedeagus short, curved slightly dorsally, with a dorsal un- 
paired process. Paraphyses present, stalked, with slender elongate rami. Anal 
tube with an anteapical ventral process. 
Female abdominal sternum VII with posterior margin produced laterally on 
each side, with a broad median shallow emargination within which median 
portion is obtusangularly produced. Ovipositor with second valvulae each 
broadened beyond basal curvature and with sloping quadrate primary teeth 
bearing minute secondary denticles, the primaries succeeded by a number of 
small anteapical teeth, apex sharply rounded, apicoventral margin without 
teeth. Pygofer without setae. 
The genus Rhopalogonia Melichar includes only the type-species, of which a 
number of specimens from Venezuela have been examined. One specimen in
