CICADELLINAE: PART 2. NEW WORLD CICADELLINI ane 
disk (exception: S. torquata, n. sp.) without sculpturing or setae, lateral clypeal 
sutures extending onto crown and usually attaining ocelli; antennal ledges not 
protuberant, in lateral view with anterior margins usually rectilinear and ob- 
lique; clypeus flattened, muscle impressions distinct or not (varying inter- 
specifically), face occasionally with weak pubescence on its lower portion, 
transclypeal suture almost always interrupted at middle, clypellus not strongly 
produced, its profile variable interspecifically, either continuing profile of 
clypeus or with contour of its lower portion more nearly horizontal. 
Thorax with pronotal width usually less than transocular width of head, 
lateral margins parallel or convergent anteriorly, dorsopleural carinae usually in- 
complete, posterior margin concave, disk usually without punctures or rugosity, 
not pubescent; scutellum transversely striate behind transverse sulcus or not. 
Forewing with or without a membrane, veins usually not very distinct, with four 
apical cells (not observed in S. absona, n. sp.) of which the base of the fourth is 
more proximal than base of third, without an anteapical plexus of veins, texture 
coriaceous; forewings of female in rest position exceeding apex of ovipositor. 
Hindleg with femoral setal formula 2:1:1, length of first tarsomere inter- 
specifically variable compared with combined length of two more distal tar- 
someres and with two parallel longitudinal rows of small setae on plantar sur- 
face. 
Male genitalia: Pygofer moderately produced, with posterior margin varying 
from regularly convex to obliquely truncate, with setae usually numerous and 
consisting entirely of microsetae or of microsetae mixed with macrosetae. Plates 
triangular and with numerous macrosetae usually not arranged in rows. Style ex- 
tending posteriorly farther than apex of connective, without preapical lobe. Con- 
nective with basal arms widely divergent, remainder usually approximately 
triangular. Aedeagus symmetrical, shaft extending dorsally and without pro- 
cesses. Paraphyses varying from distinct to indistinct or absent, symmetrical 
when present and varying from a median structure without rami to an elongate 
unpaired basal portion and paired shorter rami. 
Female abdominal sternum VII strongly keeled medially and with a strongly 
produced gradually tapered posterior triangular lobe that may be acute or 
slightly emarginate apically. Dorsal membrane of genital chamber without 
sclerites. Ovipositor with second valvulae each of uniform narrow width 
throughout length, toothed portion of dorsal margin limited to apical one-third, 
consisting of small denticles over successive convexities basally, primary teeth 
quadrate and with denticles in more apical portion, with a number of anteapical 
dorsal and ventral denticles, apex narrowly rounded or acute; third valvulae very 
broad compared to width of second valvulae. Pygofer with posteroventral margin 
strongly emarginate, delimiting a large posterior lobe which bears macrosetae 
which are specifically variable. 
This genus is named in honor of Dr. Jaroslav Stehlik, of the Moravske 
Museum in Brno, Czechoslovakia, who was most helpful during my visit there in 
1962. 
Species of Stehlikiana, new genus, occur in British Honduras, Venezuela, 
Colombia, Ecuador, Peru, Bolivia, and Brazil. Stehlikiana is related to Trichogonia 
Breddin in the treatment of which distinguishing characters are discussed.
