Description. Malar sulcus compound. Malar space partially striate, striations extending one-half to two-thirds distance from ventral margin of malar space to base of compound eye. Malar protuberance smooth, elongate, extending beyond length of ventral margin of malar space. Clypeal protuberance elongate, overhanging anterior margin of clypeus. Tubercles of scutellar plate present, distinct, large, length of tubercle equal to or greater than width of tubercle base. Dorsal surface of scutellar plate concave around midpit, two setal bearing pits at base of each tubercle. Carina along posterior margin of scutellum present, distinctly cleft, defining transition from dorsal surface of scutellum from posterior surface. Dorsal surface of scutellum entirely rugulose/wrinkled. Midpit of scutellar plate in posterior half of plate; plate small, revealing dorsal surface of scutellum when viewed dorsally. Mesopopleural setal patch absent. Mesopleuron entirely smooth; smooth anteriorly, striate along the postero-dorsal margin. Lateral aspect of pronotum anteriorly with some short setae, remainder glabrous. Marginal cell of forewing distinctly deeper than long. Metasoma of sub-equal size to mesosoma in lateral view.

Diagnosis. This species is unique within Ganaspidium as it is the only species with a horizontally striate scutellar plate. The strongly reticulate dorsal surface of the scutellum is also rather unique, only shared with G. konzaensis and G. kolmaci ; G. didionae

is separated from these two by the horizontally striate scutellar plate as well as a limited degree of striation on the malar space (fully striate in G. konzaensis ) and distinct tubercles on the scutellar plate (significantly reduced in G. kolmaci ).

Etymology. Named in honor of author Joan Didion. Several fiction and nonfiction pieces by Ms. Didion focus on the desert Southwest of the United States. The gender is feminine.
