apex; pronotum with a black band at anterior margin, remainder ivory suf- 
fused with purple or brown; scutellum dull yellow with at least the basal 
angles black; forewing dull red with two pale spots in basal half of clavus, and 
three pale spots in corium: at base, opposite midlength of clavus, and in an- 
teapical cells; clypeus with a broad black stripe continued through clypellus 
as a narrow median black stripe, remainder of face and thoracic pleura dull 
yellow; legs tan to purple. 
Holotype and one additional male, Itaitaia [Itataia?], “800 MS, 12-9-33” 
(S. Lopes and R. Cun[ Ja) (USNM). One female, Brazil (F. Sahlb.). One 
male, Petropolis, Brazil (F. Sahlberg) (MMB). 
R. tatia, n. sp. is closely related to R. glaucomaculata (Germar) from which it 
may be distinguished readily by its longer, more slender aedeagus, and by the 
form of the aedeagal processes.

Type-species: Cicadella lituriceps Osborn (1926b:180). 
Length of male 6.4-6.7 mm, of female 6.9-7.2 mm. 
Head slightly produced with anterior margin broadly convex, median 
length of crown from slightly less than one-half to six-tenths interocular width 
and from three-tenths to slightly less than four-tenths transocular width, 
without a carina at transition from crown to face, ocelli located in line with 
anterior eye angles, each equidistant from adjacent anterior eye angle and me- 
dian line of crown, crown with a shallow transverse concavity across ocelli, 
without a median fovea and without sculpturing or setae, lateral clypeal 
sutures extending onto crown and attaining ocelli; antennal ledges not pro- 
tuberant in dorsal view, in lateral view with anterior margins oblique and 
convex; clypeus slightly flattened medially, muscle impressions distinct; trans- 
clypeal suture entire or interrupted medially, clypellus in profile with its lower 
portion more nearly horizontal than remainder of face. 
Thorax with pronotal width less than transocular width of head, lateral 
margins very short, parallel, dorsopleural carinae complete, posterior margin 
shallowly concave, disk with or without transverse rugae; scutellum rugose or 
not behind transverse sulcus. Forewing with membrane including all of apical 
cells and extending proximad along costal margin, veins distinct, with inner 
anteapical cell open basally and bases of outer two anteapical cells proximal 
to claval apex, with four apical cells of which base of fourth is more proximal 
than base of third, without an anteapical plexus of veins, texture opaque. 
Hindleg with femoral setal formula 2:1:1 or 2:1:1:1, length of first tarsomere 
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, narrowly rounded postero- 
dorsally, without processes, macrosetae parallel to posteroventral margin, 
arranged irregularly. Plates short triangular, not extending posteriorly nearly 
as far as pygofer apex, with uniseriate macrosetae. Style not extending
