CICADELLINAE: PART 2. NEW WORLD CICADELLINI 1057 
and essentially uniseriate; aedeagus in ventral view with shaft not very broad, 
with a pair of ventral anteapical recurved processes; aedeagus in lateral view 
with shaft very broad, and broadest anteapically. Female abdominal sternum 
VII with posterior margin more narrowly convex than in other species. Face 
of male with clypeus and clypellus black except for a narrow lateral marginal 
yellow to orange stripe on each side of clypeus, extending onto clypellus in 
some specimens. 
Holotype and 11 additional males, Coroico, Yungas, Bolivia, April 16, 
1899; one male, same locality, April, 1899; two males, same locality, Novem- 
ber 20 and December 9, 1898; two females, Coroico, Bolivia (OSU). Also 12 
males, Yungas de Palmar, Bolivia, 100 m., November, 1960 (A. Martinez) 
(SSM). Two males, Coroico, Bolivia, both bearing ‘“‘typus” labels and a 
Melichar manuscript name (HNHM). 
T. hamata, n. sp., can be separated most readily from other species of the 
genus by the distinctive form of the aedeagus of the male, in lateral view; and 
by the unlobed more narrowly convex seventh sternum of the female. 
Tortigonalia torta, NEW SPECIES 
FicurE 857, PAGE 1058 
Length of male 7.8-8.2 mm. Male pygofer in lateral view with posteroven- 
tral margin strongly concave subapically, the pygofer appearing almost con- 
stricted as a result, macrosetae on apical lobe, and a few microsetae along 
ventral margin; plates with uniseriate macrosetae; aedeagus very short and 
broad in ventral view, and with lateral margins of shaft convex basad of the 
single pair of apical retrorse processes, in lateral view with shaft not as broad 
anteapically as in 7. hamata, n. sp. Face of male with clypeus varying from 
completely yellow except for a black spot at transition to crown to pre- 
dominantly black except laterally, the variation being the degree to which the 
dark marking extends ventrally from the dorsal portion of the clypeus; 
clypellus, lora, and genae, pale yellow, in some specimens with a small black 
spot below antennal base. 
Holotype male and 16 additional males, Monsén Valley, Tingo Maria, 
Peru, December 9, 1954 (E. I. Schlinger and E. S. Ross); four males, same 
data except December 23, 1954; six males, same data except November 10, 
1954: and one male, same data, except December 2, 1954 (CAS). One male, 
Callanga, Peru (ZIL). One male, labeled ‘‘Peru” and bearing a Melichar 
determination label (a manuscript name) and a ““Typus” label (HNHM). 
One male, Yungas de Palmar, Bolivia, 1100 m., November, 1960 (A. Mar- 
tinez) (SSM). I have also studied, earlier, a male from “‘Itaituba”, Brazil from 
the USNM collection. 
T. torta, n. sp., can be separated most readily from other species of the 
- genus by the character combination of aedeagal form and uniseriate setae on 
the male plates.
