CICADELLINAE: PART 2. NEW WORLD CICADELLINI 35 
Holotype male, Tingo Marfa, Hudnuco Province, Peru, October 8, 1946, 2200 
ft. J. C. Pallister) (AMNH). One female, Cuenca, Ecuador (BM). One female, 
Loja, Ecuador (R. Oberthur), 1903 (MHNP). 
N. crassa, n. sp., is closely related to NV. rufipes Melichar, from which it may be 
distinguished readily by the more arched aedeagus and the presence of only two 
rami in the paraphyses (four in rufipes) of the male, in addition to the characters 
set forth in the key. 
2. Genus PARACATUA MELICHAR 
Ficures 4, 5 
Paracatua Melichar, 1926a:340. Type-species: Tettigonia rubrolimbata Signoret, by subse- 
quent designation of China (1938d:183). 
Length of male 9.5-10-8 mm, of female 9.5-9.9 mm. 
Head moderately produced, median length of crown varying from slightly less 
than four-tenths to one-half interocular width and from one-fourth to almost one- 
third transocular width, anterior margin broadly rounded, ocelli each slightly 
closer to median line than to adjacent anterior eye angle; antennal ledges slightly 
protuberant in dorsal view, in lateral view with anterior margins rectilinear and 
nearly vertical; clypeus convex, clypellus not produced, its profile almost con- 
tinuing contour of clypeus, pubescent. Other head characters as in WNewva 
Melichar. 
Thorax with pronotal width greater than transocular width of head, posterior 
margin very shallowly concave, disk indistinctly, transversely rugulose; 
scutellum transversely rugulose behind transverse sulcus, with surface not con- 
vex. Forewing without a membrane, veins obscure, not elevated. Hindleg with 
tibial setae of rows 1 and 2 approximately equal in size, both widely spaced, row 
2 with intercalary small macrosetae; length of first tarsomere less than combined 
length of two more distal tarsomeres. Other characters as in Neiva. 
Male genitalia: Pygofer not strongly produced, its apical margin convex, with 
a number of short macrosetae near and parallel to posterior margin. Plates short, 
subtriangular, not extending nearly as far posteriorly as pygofer apex, fused at 
base, with numerous regularly spaced multiseriate microsetae. Style slender, ex- 
tending posteriorly very much beyond apex of connective, without a preapical 
lobe. Connective very short, somewhat quadrate, not keeled medially. Aedeagus 
symmetrical, shaft very short, with a pair of short lateral, and a pair of apical 
processes. Paraphyses biramous, the arms slender, tapering, and symmetrical. 
Female (Paracatua reichi (Signoret) not dissected) abdominal sternum VII very 
short, its posterior margin with two convex lobes separated by a shallow median 
angular excision. Genital chamber with sclerotization of dorsal membrane exten- 
sive and complex. Ovipositor with second valvulae as in Newa. Pygofer as in 
Neiva, but with sparse macrosetae near posterodorsal and posterior margin. 
Paracatua Melichar occurs in Colombia and Venezuela. The genus is related to 
Neiva in the discussion of which diagnostic characters are treated. 
Although I have seen the lectotype, a female, of Tettigonia reichi Signoret, the 
present interpretation of this species is based on two male specimens from 
Venezuela (AMNH) which agree fairly well with Signoret’s original illustration.
