CICADELLINAE: PART 2. NEW WORLD CICADELLINI 139 
D. costalimai, n. sp. is closely related to D. dispar (Germar) from which it 
may be distinguished by the distinctive markings of its anterior dorsum and in 
the aedeagus which lacks the stronger separation between the lobe of the 
aedagus and shaft of the Germar species. 
This species is named in honor of Angelo M. da Costa Lima whose work 
has contributed much to our knowledge of neotropical Homoptera. 
Dilobopterus manni, NEW SPECIES 
FicuRE 83, PAGE 124 
Length of male 8.4 mm. Head with median length of crown slightly greater 
than one-half interocular width and one-third transocular width, anterior 
margin much more produced than in D. axillaris, n. sp., very broadly rounded 
in dorsal aspect; antennal ledges with anterior margins obliquely convex, 
without a dorsal carina. Forewing with a single membranous area before 
apical membrane, veins indistinct in basal one-half; hindwing with jugal lobe 
enlarged. Other external characters as in axillaris. 
Pygofer well produced with macrosetae close-set and fairly uniformly dis- 
persed, with short mesally directed process from each dorsal margin in dorsal 
aspect; plates not extending posteriorly as far as pygofer apex, each slender, 
triangular, abruptly narrowed in basal third, with uniseriate macrosetae 
throughout most of length; style extending posteriorly much beyond apex of 
connective, with a preapical lobe; connective short, Y-shaped with stem very 
short and arms widely divergent, without a median keel; aedeagus sym- 
metrical with a prominent dorsal lobe separated from shaft by an angular ex- 
cision; paraphyses asymmetrial, consisting of two elongate asymmetrical slen- 
der rami arising from base, one of these branched at apex. 
Crown black, an anchor-shaped marking at apex, a pair of reversed 
parentheses-shaped markings near middle of base, several arcs in area of mus- 
cle impressions, a C-shaped marking tangential to each inner eye margin, a 
short pale marking before each ocellus, an angular spot laterad of preceding, 
a narrow laterobasal marginal marking extending from behind each ocellus 
parallel to posterior eye margin, yellow; pronotum greenish yellow, lateral 
and posterior margins fuscous, anterior margin black with a number of ir- 
regular yellow markings; scutellum black with a pair of median markings near 
base, basal angles narrowly, and entire apical half, yellow. Forewing hyaline, 
costal margin to bases of apical cells, humeral margin, commissural margin, 
claval suture, black, a broad transverse fuscous area through bases of ante- 
apical cells, including basal halves of latter, and attaining commissural 
margin; hindwing with jugal lobe black, extending posteriorly slightly beyond 
midlength of clavus with wings in rest position. Face yellow with a median 
longitudinal black stripe which is bifurcate basally, expanding ventrally to in- 
clude all of clypellus and portion of lora and genae. Thoracic pleura and legs 
except at their black bases and apices, pale yellow.
