CICADELLINAE: PART 2. NEW WORLD CICADELLINI 381 
S. umaritubanus, n. sp., is closely related to S. klagesi, n. sp. (p. 390), from 
which it may be distinguished readily by its apicoventral aedeagal process 
which is absent in k/agest, and from all other species of the genus by the dis- 
tinctive structure of the female abdominal sternum VII. 
Soosiulus dextrorsus, NEW SPECIES 
FicuRE 304 
Length of male 7.1 mm, of female 7.4-7.5 mm. Head with median length of 
crown from slightly more than one-half to slightly less than seven-tenths inter- 
ocular width, and from slightly less than four-tenths to slightly greater than 
four-tenths transocular width, ocelli located slightly behind a line between an- 
terior eye angles, each approximately equidistant from adjacent anterior eye 
angle and median line of crown. Other external structural characters as in S. 
interpolis, n. sp., (p. 374). Male pygofer with a group of microsetae near 
posteroventral margin in addition to discal macrosetae, and with three or four 
enlarged scalelike setae along posterior margin; plates not extending nearly as 
far posteriorly as pygofer apex, with few uniseriate macrosetae; style ex- 
tending posteriorly farther than apex of connective; connective semi-oval in 
form, with a median keel in apical half; aedeagus asymmetrical, shaft slender 
_and tubular, with a long slender acute apical process extending dextrad; para- 
physes with a long broad stalk which bears a lateral lobe on each side near 
base of rami, rami without basal lobes. Female abdominal sternum VII with 
posterior margin regularly and broadly convex.
