Thorax with pronotal width equal to or less than transocular width of head, 
lateral margins parallel or slightly convergent anteriorly, dorsopleural carinae 
complete, posterior margin concave, disk obscurely transversely rugulose in 
some specimens, not pubescent; scutellum not striate behind transverse 
sulcus. Forewing with membrane including all of apical cells, veins indistinct, 
with three closed anteapical cells, with four apical cells, the base of fourth 
more proximal than base of third, without an anteapical plexus of veins, tex- 
ture coriaceous 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 two more distal tarsomeres, 
and with two parallel rows of small setae on plantar surface. 
Male genitalia: Pygofer strongly produced posteriorly, narrowed apically to 
dorsoapical margin which is narrowly rounded to acute, with few macrosetae 
occurring in anteapical group. Plates triangular, extending posteriorly as far 
as pygofer apex, with uniseriate macrosetae. Style extending posteriorly as far 
as, or farther than apex of connective, obliquely truncate apically, with 
preapical lobe. Connective Y-shaped with arms widely divergent. Aedeagus 
simple, short, without processes. Paraphyses absent. 
Female abdominal sternum VII with median portion of posterior margin 
slightly produced and slightly emarginate. Genital chamber without sclerites. 
Ovipositor with second valvulae each broadly expanded beyond basal cur- 
vature and with large dorsal quadrate teeth not extending quite to narrowly 
convex apex, with minute secondaries on the primary teeth and with an- 
teapical denticulations on posterodorsal and posteroventral margins. Pygofer 
with sparse macrosetae on posterior half. 
Species of Hortensia are dull yellow anteriorly, with the disk of the scutel- 
lum darker, and the head and anterior submarginal area of the scutellum 
marked with black. The black markings coalesce to some extent, and it is 
possible to sort segregates on the basis of color. I have been unable to find 
structural characters to support the color differences, to date, except in the 
case of the new species described below. There are minor intraspecific dif- 
ferences, also, in the shape of the aedeagus. 
Hortensia similis (Walker) is the commonest species of Cicadellini in the New 
World and one of the most widespread. Specimens have been examined from 
southern U. S. A., numerous localities in Mexico, Central America, the West 
Indies, and all of the countries of South America except Uruguay and Chile. 
This range is the same for the genus. The genus is similar in many respects to 
Kapateira, new genus, and the latter may eventually be reduced to synonymy 
under Hortensia, especially if females of Kapaterra, presently unknown, support 
such an action. Hortensia species are smaller than Kapateira (6.3 mm at most 
vs. 7.5 mm at least), have a more strongly produced male pygofer and with its 
setae more restricted, have the connective in the form of a Y instead of a 
transverse bar or very short Y, and have the aedeagus very short compared to 
the longer aedeagus (usually) of Kapateira. 
Host plant records of H. similis (Walker), although numerous, do not show 
whether the specimens were feeding or not. These records include, from 
Colombia: corn (Antioquia: Bello and Medellin; Valle: Palmira; Meta:
