description: Graphocephala riverae, sp. nov. (Figs 6–10)
Type material: Holotype, male, COSTA RICA: Heredia: P. N. Braulio Carrillo, Est. Barva, 2500 m, XII­1989, Col. A. Fernández, L­N 233400­523200 (INBio). Paratypes, 1 male same data as holotype except IX­1989 (INBio), 1 male same data except III­1990 (UCR), 2 males and 2 females same data (CAS, NHM, UCR, INBio), 2 males same data except V­1990 (INBio), 1 male and 1 female same data except VI­1990 (INBio), 1 female same data except XI­1989 B. Apu & G. Varela (INBio), 2 females same data except VI­ 1990 (INBio), female same data except VII­1990 (INBio).
Description. Length of male 7.0– 8.2 mm, female 7.7–8.3 mm. General color yellowish green. Head moderately produced, anterior margin subangulate, broadly rounded in dorsal view; crown dark yellow with black markings, broad ivory­blue band along anterior margin, band bordered by thin black line; ocelli located on a line between anterior eye angles (Fig. 6); clypeus black, medially nearly flattened, muscle impressions distinct. Pronotum mostly dark green with light blue band anteriorly, band bordered with dark yellow or sometimes with black markings; pronotal width slightly greater than transocular width of head (Fig. 6). Scutellum yellowish green with black markings (Fig. 6). Forewing yellowish green with membrane not distinct, costal margin black, claval area darker; veins distinct; in general with three closed anteapical cells and four apical cells; forewings of female in resting position exceeding apex of ovipositor. Legs orange; hind leg with femoral setal formula 2:1:1, length of first tarsomere greater than combined length of two remaining tarsomeres and with two rows of small setae on plantar surface.
Male genitalia: Pygofer moderately produced, apex convex, with macroseae confined to apical half of disc, dorsal process absent (Fig. 7). Subgenital plate triangular with macrosetae arranged in one row (Fig. 7). Style extending posteriorly to a varying degree compared to extent of connective, without a distinct preapical lobe (Fig. 8). Connective with very long stem, extending beyond apex of styles (Fig. 8). Aedeagus in lateral view nearly V­shaped, with shaft short, without processes, dorsal apodeme conspicuous (Fig. 9). Paraphyses consisting of a basis and two rami, dorsal ramus shorter (Fig. 9). Female abdominal sternum VII with margin produced posteriorly, the apex varying from rounded to obtusely or acutely angular (Fig. 10).
Diagnosis. This species is similar to G. coronella in that the aedeagus is V­shaped in lateral view in both species, but the paraphyses are wider in G. riverae. In addition, the dorsal ramus is longer than that of G. c o ro n e l l a and the caudodorsal margin of the pygofer more deeply concave in lateral view.
Distribution. Known only from Costa Rica.
Biology. Unknown
Etymology. This species is name in honour of Carmen Rivera, in recognition of her dedication to the study of plant virology in Costa Rica.
