CICADELLINAE: PART 2. NEW WORLD CICADELLINI 411 
ocelli located on or before a line between anterior eye angles, variable in re- 
lation to comparative distance from median line of crown and anterior eye 
angle, crown usually with a shallow transverse concavity before ocelli, without 
sculpturing except granulations near apical margin, lateral clypeal sutures ex- 
tending onto crown and attaining ocelli; antennal ledges not protuberant, in 
lateral view with anterior margins oblique and varying (within species) from 
rectilinear to slightly convex; clypeus convex, not tumid, muscle impressions 
usually not distinct, face without pubescence, transclypeal suture not com- 
plete, clypellus not produced, its contour almost continuing profile of clypeus. 
Thorax with pronotal width equal to or slightly less than transocular width 
of head, lateral margins convergent anteriorly, dorsopleural carinae complete, 
posterior margin concave, disk rarely (variable intraspecifically) with a few 
weak transverse rugae, not pubescent; scutellum usually without transverse 
striae on portion behind transverse sulcus. Forewing without a distinct mem- 
brane, with apical portion less opaque than remainder but not abruptly de- 
limited, with four apical cells and with base of fourth more proximal than 
base of third, without an anteapical plexus of veins, anteapical cells with their 
bases occurring before apex of clavus (exception: middle anteapical cell of M. 
illustris (Signoret)) or obscured (:/lustris, base of outer anteapical cell), texture 
coriaceous except apically, veins not very distinct, apical margin regularly 
convex; forewings of female in rest position exceeding apex of ovipositor. 
Hindleg with femoral setal formula 2:1:1, length of first tarsomere much 
greater than combined length of two more distal tarsomeres and with two 
parallel rows of small setae on plantar surface. 
Male genitalia: Pygofer moderately produced, with apical margin varying 
interspecifically from broadly convex to acutely subangular, with macrosetae 
fairly numerous and with arrangement varying interspecifically; dorsal margin 
usually with an undifferentially sclerotized lobe near its midlength. Plates 
short, triangular, not extending posteriorly nearly as far as pygofer apex, with 
few uniseriate macrosetae. Style extending posteriorly beyond apex of con- 
nective, narrowly rounded or truncate apically, without a preapical lobe; con- 
nective Y- or T-shaped. Aedeagus usually symmetrical, occasionally asym- 
metrical as result of the processes being not quite similar, or as result of only 
one process being present and not in median plane. Paraphyses usually ab- 
sent (exceptions: M. apicula (Osborn) and M. quevedoents, n. sp.). 
Female abdominal sternum VII with posterior margin produced and 
angulate. Ovipositor with second valvulae each broadened in apical two-thirds 
of distance beyond basal curvature and bearing dorsal teeth which are simi- 
lar throughout, teeth somewhat bilobed and bearing minute secondary denti- 
cles, apex bluntly rounded, without anteapicai dorsal and ventral denticles (at 
120X). Pygofer with a number of irregularly arranged macrosetae on apical 
two-thirds. 
Specimens belonging to Microgoniella Melichar have been examined from 
Costa Rica, Colombia, Venezuela, and the Guianas, and south to Bolivia and 
Brazil. Specimens of Microgoniella are similar in size and appearance to those 
of Juliaca Melichar, but differ in that paraphyses are usually absent or great- 
ly reduced in Microgoniella and in that aedeagal processes are usually present. 
Similarities to Pachitea Melichar are discussed in the treatment of that genus.
