( 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 .
