CICADELLINAE: PART 2. NEW WORLD CICADELLINI 47 
transverse concavity, without a median fovea and without sculpturing or setae, 
lateral clypeal sutures extending onto crown but not attaining ocelli; antennal 
ledges not protuberant, in lateral view with anterior margins rectilinear and ob- 
lique; clypeus slightly flattened medially, muscle impressions distinct, without 
pubescence, transclypeal suture obsolete medially, clypellus weakly and obtusely 
subangulate in profile, weakly pubescent. 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae complete, posterior margin weakly con- 
cave, disk weakly rugulose or not, not pubescent; scutellum not striate behind 
transverse sulcus. Forewing with only inner apical cell membranous, veins 
elevated and distinct, with four apical cells, the base of the fourth more proximal 
than base of third, without an anteapical plexus of veins, texture coriaceous and 
without sculpturing; forewings of female in rest position exceeding apex of ovi- 
positor. Hindleg with femoral setal formula 2:1:1, length of first tarsomere 
greater than combined length of second and third tarsomeres, with two parallel 
rows of small setae on plantar surface. 
Male genitalia: Pygofer moderately produced, posterior margin broadly con- 
vex, with a number of macrosetae on posterior and posteroventral portions of 
disk and a group of more closely spaced macrosetae near middle of disk; plates 
short, abruptly narrowed at or beyond midlength, not extending posteriorly as 
far as pygofer apex, with multiseriate macrosetae and with a number of elongate 
microsetae on lateral margins; style extending posteriorly farther than apex of 
connective, without a preapical lobe; connective narrowly Y-shaped, with arms 
not widely divergent, strongly keeled; aedeagus simple, broadened apically, 
without processes or with inconspicuous ventral processes near base of shaft. 
Paraphyses present, slightly decurved in apical half. 
Female abdominal sternum VII elongate, abruptly narrowed in apical one- 
fourth to a narrow median truncate lobe. Dorsal membrane of genital chamber 
with a pair of poorly delimited sclerotized areas. Ovipositor with second valvulae 
slender, with few poorly developed teeth on dorsal surface in apical one-fourth. 
Pygofer with short macrosetae, unevenly distributed on apical half of disk 
(female of type-species unknown). 
Specimens of 7Tahuampa are known from Venezuela and Peru. I have placed 
Tahuampa, new genus, near Agrosoma Medler, chiefly because of the similarity of 
the female second valvulae and the multiseriate male plates. The produced 
female sternum VII suggests a relationship to the 7richogonia Breddin generic 
group (see below), but the lateroventral emargination of the female pygofer is 
lacking. 
The lectotype of Tettigonia septemfasciata Signoret agrees with the illustrations 
published here.
