CICADELLINAE: PART 2. NEW WORLD CICADELLINI Ties! 
narrowed to acute apex; connective subquadrate with a median keel; 
aedeagus curved gradually posteriorly and dorsally through 90°, without 
processes. Female abdominal sternum VII with posterior margin deeply V- 
shaped, with base of emargination truncate and sides somewhat sinuate; 
pygofer with apex subacute, macrosetae elongate, sparse, arranged in basal 
and anteapical groups and a few located along posteroventral margin; genital 
chamber with a pair of conspicuous processes arising one on each side behind 
apex of sixth sternum, each slender and extending posteriorly. Other struc- 
tural characters as in generic description. 
Color of crown and pronotum black, a broad triangular marking bordering 
basal margin of crown and a median pronotal marking over basal three- 
fourths, ivory, the latter separated from the former by the narrow anterior 
black margin of pronotum; scutellum and forewings smoky brown with a 
transverse transcommissural pale marking on forewings behind scutellum, not 
attaining costal margins, and a subhyaline corial marking extending from 
behind claval apex to costal margin on each wing, gradually widened towards 
costa, claval apices pale; face, thoracic pleura, venter, and legs, stramineous. 
Holotype male, one additional male and four females, Abitagua, Ecuador, 
1200 meters, May 25, 1939 (W. Clark-Macintyre); one pair, Oriente, Ecuador, 
and one male, “Rio Arajuno”’, Napo Watershed, Ecuador (NCS). Holotype on 
indefinite loan to USNM. 
E. ektla, n. sp., is most closely related to E. notatula Melichar but is unlike 
all other species of the genus in that pale markings of crown and pronotum 
are separated by the black anterior pronotal margin. The male genitalia are 
closer to Medler’s (1963a:30) illustration of E. sparta Melichar than to any of 
the other species in the genus. 
The processes of the female genital chamber of E. eki/a are in similar location 
to those found in some other species of Erythrogonia. Processes arising near the 
laterobasal margins of the seventh sternum, from either the membrane of the 
genital chamber or from the first valvifer are found in areolata (Signoret), phoenicia 
(Signoret), signoreti Schmidt, jucunda (Walker) and colorata (Germar). In several 
other species there is some sclerotization of the membrane of the genital chamber 
in this area, but not in the form of definite processes. In ekila, these processes are 
not visible in dried specimens, but are quite distinct after maceration in KOH. In 
some species, e.g. areolata (Signoret), the processes are quite distinct externally, 
although not shown in any of the published illustrations.

FIGURE 629, PAGE 774 
Length of male 6.2-6.8 mm, of female 6.4 mm. Head with median length of 
crown from six-tenths to three-fourths interocular width and from slightly less 
than four-tenths to slightly greater than four-tenths transocular width. Fore-
