punctate or rugose, often with fine sparse pubescence; forewings of female in 
rest position exposing apex of ovipositor or not. Hindleg with femoral setal 
formula 2:1:1 or 2:0:0 (variable interspecifically), tibiae with setae of rows 1 
and 2 sparsely spaced and with intercalary microsetae, first tarsomere with 
length equal to or greater than combined length of two more distal tarsomeres 
and with numerous irregularly spaced small setae on plantar surface. 
Male genitalia: Pygofer weakly produced, posterodorsal margin obliquely 
sloping to convex apex at middle of posterior margin, with a number of small 
macrosetae, or of microsetae, without pygofer processes. Plates narrowly 
triangular, extending as far posteriorly as apex of pygofer, with a number of 
irregularly arranged microsetae. Style slender, without preapical lobe, acute 
or truncate at apex. Connective Y-shaped, with arms as long as stem. 
Aedeagus very short, not strongly curved, rounded apically, without processes. 
Paraphyses asymmetrical, similar to those of Graphocephala spp. (e.g. G. coccinea 
(Forster) ). 
Female abdominal sternum VII transverse, slightly produced posteriorly 
and bluntly angulate apically, surface with numerous irregularly arranged 
microsetae. Dorsal membrane of genital chamber without sclerites. Ovipositor 
with second valvulae each gradually broadened beginning in basal fifth, with 
dorsal teeth in slightly more than apical half, the primaries not prominent 
near base, where arrangement is consequently an alternation of a convexity 
without denticles with a number of minute denticles, the more distal 
primaries more elevated and the denticles appearing as secondaries, with a 
number of anteapical dorsal and ventral denticles, apex acute. 
Both species are brown to black. The genus Allonolla is known only from 
Mexico. The male genitalia are similar to a number of species of Graphocephala 
Van Duzee. The absence of an appendix in the forewing is different from 
almost all other species in the Cicadellinae. The only biological information 
available is that two specimens were intercepted on a species of orchid from 
Michoacan, Mexico.
