CICADELLINAE: PART 2. NEW WORLD CICADELLINI 1049 
marked with black, transclypeal suture obsolete at middle, clypellus not 
produced, its contour continuing profile of clypeus. 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae complete, disk not or very obscurely 
sculptured, not pubescent; scutellum not transversely striate behind trans- 
verse sulcus. Forewing with membrane present, usually not sharply delim- 
ited basally (in some specimens basal portions of apical cells 2, 3, and 4 are 
opaque), inner apical cell always membranous, veins not elevated, not very 
distinct, with three closed anteapical cells, the bases of all of which are prox- 
imal to a line drawn across the wing at claval apex, with four apical cells, the 
base of the fourth more proximal than base of third, without an anteapical 
plexus of veins; forewing of female in rest position exceeding apex of ovipos- 
itor. Hindleg with femoral setal formula 2:1:1; length of first tarsomere great- 
er than combined length of two more distal tarsomeres, and with two paral- 
lel rows of small setae on plantar surface. 
Male genitalia: Pygofer strongly produced and convex posterodorsally, with 
a number of macrosetae of varying sizes on apical one-third and extending an- 
teroventrally on and near posteroventral margin, with a number of microsetae 
located anteroventrally, pygofer processes absent. Plates triangular, their 
posterior extent varying interspecifically, with numerous fine elongate 
microsetae and with macrosetae present or absent (variable interspecifically), 
not uniseriate when present. Style slender, extending posteriorly beyond apex 
of connective, slightly curved and truncate apically, without preapical lobe. 
Aedeagus with shaft short, four-lobed apically, without processes, dorsal 
apodemes variable. Paraphyses slightly variable intraspecifically but always 
consisting of an elongate slender base, furcate in apical half, the branches 
variable in length, the entire structure usually asymmetrical both in shape 
and in that it is not median in location (exception: B. cruciatula (Breddin) in 
which it is median and symmetrical). 
Female abdominal sternum VII moderately to considerably elongate with 
posterior margin produced medially, the apex angular, rounded, or slightly 
emarginate. Genital chamber without sclerites. Ovipositor with second valvula 
having toothed portion variable interspecifically in extent, bearing broad dor- 
sal quadrate teeth each with a number of minute secondaries; apex acute and 
with numerous posterodorsal and posteroventral anteapical denticles. Pygofer 
moderately produced, rounded apically, with macrosetae on posterior half. 
Species of Borogonalia are greenish yellow on crown, pronotum (except disk), 
scutellum, and face, with the forewing and pronotal disk darker green. The 
crown, scutellum, and often the face, are marked with black. 
Specimens of Borogonalia, new genus, have been studied from Venezuela, 
Colombia, Ecuador, Peru, Bolivia, southeastern Brazil, and northern Argen- 
tina. This genus is very similar in external appearance to Tortigonalia, new 
genus. The two genera are readily separable by the long fine setae of the male 
plates, and the absence of drastic modifications of the style apices in 
Borogonalia. Paraphyses are median and vestigial in Tortigonalia, usually well- 
developed and asymmetrical in Borogonalia (exception: cruciatula). The male 
genitalia are similar to those of Caldwelliola, new genus, except as pointed out 
in the treatment of the latter.
