CICADELLINAE: PART 2. NEW WORLD CICADELLINI 83 
flattened medially) in profile with a slight median protuberance on lower half 
of clypeus, muscle impressions distinct, without pubescence or with pubes- 
cence indistinct. 
Pronotum with hind margin often very steeply declivous, usually concave 
medially, rarely convex, disk usually punctate, occasionally rugose or rugose 
and punctate, scutellum with posterior half elevated in profile. Forewing with 
or without a membrane, usually not well-delimited and variable intra- 
specifically when present, veins usually not elevated, indistinct, apical cells 
usually indistinct, often with supernumerary anteapical crossveins which form 
an anteapical plexus of veins, texture coriaceous. Hindleg with femoral setal 
formula 2:1:1; length of first tarsomere equal to or greater than combined 
length of second and third tarsomeres, with two parallel rows of short setae 
on plantar surface. 
Male genitalia: Pygofer strongly produced, macrosetae varying in size from 
very large to quite small, usually distributed on posterior half of disk, oc- 
casionally on posteroventral and ventral margin also, with processes present 
or absent, arising on dorsal or apical margin when present. Plates triangular, 
separate throughout their length, usually not extending nearly as far 
posteriorly as pygofer apex, usually with uniseriate macrosetae, often with 
numerous microsetae also. Style with length variable interspecifically with re- 
lation to connective, with or without preapical lobe, truncate or not apically. 
Connective Y- or broadly V-shaped, often with median carina. Aedeagus with 
at least an apical dependent process. Paraphyses present or absent. 
Female with abdominal sternum VII very strongly produced posteriorly, 
with a complex large sclerite or sclerites in genital chamber varying inter- 
specifically. Second valvulae each bearing quadrate teeth with secondaries on 
apical one-half to two-thirds of dorsal margin beyond basal curvature, apex 
narrowly rounded, apicoventral margin rectilinear, dorsal margin convex an- 
teapically and slightly concave more proximally. Pygofer either with long 
macrosetae on disk and near apex or with shorter macrosetae distributed sub- 
marginally along posteroventral margin and near apex. 
Species of Apulia are pale yellow, pink, yellow marked with purple or purple 
marked with yellow. 
The range of Apulia Distant is from Colombia to Bolivia. Externally the 
species resemble species of <aruma Melichar, and the two genera are similar 
in a number of other respects, also. The form of the aedeagus in Apulia is dis- 
tinctive, and in the females, the abdominal sternum VII is less tapered than in 
Karuma, and is often truncate or emarginate. 
Apulia is the first genus included in the Dilobopterus generic group. This is a 
larger group of genera than those of the Neva and Trichogonia generic groups, 
and much less homogeneous than the last two. The grouping is tentative, and 
includes several complexes of genera, briefly discussed in the generic treat- 
ments below. Additional studies, especially of finer details of the comparative 
morphology of the female genitalia than have been observed, and of the 
biology of the included genera will certainly result in refinements and changes 
in concepts of the relationships of the genera included in this generic group.
