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
