Graphocephala crusa Godoy , sp. nov. ( Figs 1–5 )

Type material: Holotype, male, COSTA RICA: San José: Desamparado, 1200 m, 5­I­ 2001, Col. C. Rodríguez ( INBio). Paratypes 17 males and 9 females same data ( CAS, NHM, UCR, INBio), 1 male same data except 8­II­2000 ( UCR), 1 male and 2 females same data except 21­XII­2000 ( INBio, UCR), 1 male and 2 females same data except XII­ 2000 ( UCR), 1 male same data except 29­X­2001 ( UCR).

Description. Length of male 5.5–6.6 mm, female 5 5.– 6.5 mm. General color green. Head produced, anterior margin subangulate, yellowish­green, with an apical spot, a small spot on each antennal ledge, an oblique linear mark on ocellocular area near inner eye margin, a broader linear mark on upper margin of area of muscle impression, and vertex with four black longitudinal lines, these connected apically and basally ( Fig. 1 ); face uniform yellow, clypeus convex medially, muscle impressions distinct. Thorax with pronotal width shorter than transocular width of head; pronotum with broad yellow band bordering anterior margin, large green area occupying most of remainder. Scutellum yellow with black markings ( Fig. 1 ). Forewing with membrane distinct; with three closed anteapical cells and four apical cells green, commissure yellow, claval suture dark brown to black. Spinulation of apex of hind knees 2:1:1; legs yellow, anterior tibia with distal spot dark brown and third tarsomere on fore leg dark brown; hind leg with length of first tarsomere approximately equal to combined length of two remaining tarsomeres.

Male genitalia: Pygofer in lateral view with concave caudodorsal margin, moderately produced, apex convex, with macrosetae confined to apical half of disc, process absent ( Fig. 2 ). Subgenital plate triangular, not extending nearly as far posteriorly as pygofer apex, with uniseriate macrosetae ( Fig. 2 ). Style without preapical lobe ( Fig. 3 ). Connective with very long stem, extending beyond apex of styles ( Fig. 3 ). Aedeagus in lateral view nearly V shaped, with shaft short, without processses, dorsal apodeme conspicuous ( Figs. 4 ). Paraphyses consisting of a basis and two dissimilar rami of which the posterior one is broader and longer than the anterior one ( Fig. 4 ).

Female abdominal sternum VII with margin produced posteriorly, the apex rounded ( Fig. 5 ).

Distribution. Known only from Costa Rica.

Diagnosis. This species is most similar to G. kukla (Young) in general habitus but G. crusa can be distinguished by the wider paraphyses and the configuration of the rami. Natural History. The specimens were collected with a suction pump and yellow sticky traps in coffee, Coffea arabica (Rubiaceae) , plantations. Tests utilizing DAS­E LISA detected the presence of Xylella fastidiosa in the bodies of this species, although tests have not yet been carried out to determine whether it is a vector of this bacteria. Etymology. Named for the CRUSA fundation, which provided financial support for this project.

Biology. Of a total of 27 individuals which were tested with DAS­ELISA, 18 were positive for Xylella fastidiosa .
