A large leafhopper (female 5.5–6.0 mm; male 4.5–5.0 mm) lacking dark markings on the head. The densely reticulate forewings are similar to those of X . flaviceps , but X. fulgidum may be distinguished by the comparatively smaller ocelli (distance between ocelli greater than 7 times ocular width and ocelli located more than 2 times ocular width from edge of crown). Head. Clypellus-frontoclypeus junction in lateral view distinctly angular (90%) or evenly convex, (10%); frontoclypeus entirely yellow with brown muscle scars variably developed. Crown lacking dark markings or lines anterior margin, angular; white band along boundary with face either complete (43%), present but broken by face color (43%), or absent (14%); orange pigment absent; in lateral view concave. Distance from ocelli to lateral edge of head more than 2 times ocelli width and distance between ocelli at least 7.5 times ocelli width. Thorax. Pronotum with dark green to brown circular markings absent; circular indentations absent (90%) or present (10%); midline concolorous with lateral areas. Proepisternum with posterior edge not irregular (62%) or irregular (38%). Mesonotum, green, exposed areas unmarked. Forewing. Mainly green, including anal veins. Apex densely reticulate with many crossveins. Legs. Hind femur macrosetal formula 2+1. Plantar surface of hind tarsomere with 4-5 paleate setae. Abdomen. Sterna of male mostly yellow (100%). Male genitalia. Pygofer basolateral setae scattered and erect; subgenital plate with macrosetae absent; pygofer and subgenital plates with fine setae present. Aedeagal shaft in lateral view with dorsal process acute, not compressed, wider than tall; in ventral view broadly ovoid; shaft in dorsal view not compressed. Ventral flange not distinct. Paraphyses in dorsal view forming “U”. Style with single seta. Material examined. We coded 11 males and 10 females . Approximately 100 additional specimens were examined. Host plants. Collected from vinegarweed ( Trichostema lanceolatum ). Distribution. Known only from California. Primary type . Holotype (and 85 paratypes ) deposited in the SEMC, University of Kansas. Holotype is a female in good condition. Verbatim label on holotype : Lemon Grove / Calif. 7-24-29 / B. H. Beamer.
