CICADELLINAE: PART 2. NEW WORLD CICADELLINI 519 
farther posteriorly than pygofer apex, without a dorsal lobe in lateral view, 
each in ventral view abruptly tapered in basal portion of apical third, each 
with a group of multiseriate small macrosetae; style extending posteriorly 
much farther than apex of connective, without preapical lobe, apical portion 
gradually and slightly tapered and curved, acute at tip; connective semi-ovate, 
with a median keel; aedeagus arched ventrally through most of its length, 
apex curved dorsally, without processes; paraphyses absent. Female unknown. 
Crown and anterior marginal area of pronotum greenish-yellow to dull 
yellow, with a median basal spot on crown and a spot on marginal area of 
pronotum on each side behind eye, dull orange to brick red, remainder of 
pronotum pale green variably suffused with darker green medially; scutellum 
dull orange; forewings dark green with a portion of brachial cell, narrow arch 
across bases of anteapical cells and often with a small transcomissural claval 
spot, orange-red, costa bordered with pale green to bases of anteapical cells; 
face with more than dorsal two-thirds of clypeus yellow, with a small black 
spot beneath apex of crown, remainder variously marked with black; thoracic 
pleura and legs yellow, often marked with black. 
Holotype male, Monsén Valley, Tingo Maria, Peru, November 10, 1954 (E. 
I. Schlinger and E. S. Ross) and a long series of topotypic males collected in 
October, November, and December (CAS). Two males, Paucartambo, Peru 
(ZIL). Six males, Yungas de Palmar, Bolivia, 100 m., November, 1960 
(SSM). Five males, Rioja, Peru (MMB). 
M. suspecta, n. sp., is closely related to M. ludicula (Osborn). The male 
genitalia (fig. 428) are identical in the two species. The color markings are 
similar except that the face of specimens of /udicula is entirely black, and that 
the transcommissural claval spot, present in most specimens of suspecta, is ab- 
sent in those specimens of /udicula which I have studied. M. suspecta is con- 
siderably larger than M. ludicula which is only slightly longer than 6.0 mm. 
No specimens of M. brevisula (Osborn) have been seen and there is a possi- 
bility that M. suscepta will be preempted by the last.
