137. CORONIGONIELLA, NEw GENUS 
Ficures 816-833 
Type-species: Graphocephala spinosa Osborn. 
Length 5.1-8.7 mm. 
Head moderately produced with anterior margin broadly rounded in dorsal 
view, median length of crown varying from slightly more than one-half to 
slightly more than seven-tenths interocular width and from one-third to 
approximately one-half transocular width, without a carina at transition from 
crown to face, ocelli located on a line between anterior eye angles, each equi- 
distant from median line of crown and adjacent anterior eye angle or slightly 
closer to latter, crown with or without a shallow transverse concavity across 
ocelli, without a median fovea, surface of crown without sculpturing or setae, 
lateral clypeal sutures extending onto crown to or near ocelli; antennal ledges 
not protuberant, in lateral view with anterior margins varying from vertical to 
oblique and from rectilinear to convex; clypeus usually convex medially, cly- 
pellus with contour of its lower portion usually continuing profile of clypeus. 
Thorax with pronotal width equal to or greater than transocular width of 
head, lateral margins convergent anteriorly, other thoracic characters as in 
Coronigonalia, new genus. Forewing with veins distinct, with three anteapical 
cells, of which the base of the innermost is opposite claval apex, or nearly so 
(exception: C. rubiella, n. sp.); other forewing characters as in Coronigonalia. 
Hindleg with length of first tarsomere much greater than combined length of 
two more distal tarsomeres in most species, other characters as in 
Coronigonalta. 
Male genitalia: Pygofer not as strongly produced posteriorly as in 
Corongonalia (exception: C. truncata, n. sp.), apex variable interspecifically, 
with a number of discal macrosetae on apical half; pygofer processes present 
(exception: C. baguensis, n. sp.), variable interspecifically but usually arising 
along ventral pygofer margin. Plates triangular, usually extending as far, or 
almost as far posteriorly as pygofer apex, each with uniseriate macrosetae. 
Style usually extending as far posteriorly as apex of connective or farther, 
variable apically, with a lobe near midlength of shank. Aedeagus variable 
interspecifically. Paraphyses absent. 
Female abdominal sternum VII with a median posterior acutangular 
process. Ovipositor with second valvulae each toothed through most of dorsal 
margin, the teeth widely spaced, apex acute. 
Specimens of Coronigoniella, new genus, have a red to orange-margined 
crown and are similar in appearance to specimens of the new genera 
Coronigonalia and Stephanolla. Coronigoniella occurs in the region from Costa 
Rica, Trinidad and French Guiana south to Brazil and Peru. Males may be 
distinguished from Coronigonalia and Stephanolla by their symmetrical genitalia 
and lack of paraphyses. Females of Coronigoniella have the abdominal sternum 
VII slender and acute at its apex. 
I have studied the types of Graphocephala humeralis, G. lineola, and G. spinosa, 
all described by Osborn. I have based my identification of Cicada marginella 
Fabricius on the female lectotype and specimens I believe are conspecific with 
iv;
