Nothodelphax occlusa is a little-known delphacid planthopper of the subfamily Delphacinae, tribe Delphacini. All records are from western North America: British Columbia in Canada; Arizona, California, Colorado, Nevada, Oregon, andWashington in the United States; and Baja California in Mexico. Its host plants have remained unknown. Based on fieldwork in Oregon and Washington (2007–2009), N. occlusa is reported to develop on common rush, Juncus effusus (Juncaceae), in natural stands and ornamental plantings. The presence of N. occlusa in waterside gardens and other landscape plantings suggests that it can be transported with Juncus nursery stock. It was not found on grasses (Poaceae) or sedges (Cyperaceae). All adult males collected (n 5 170) were brachypterous; females were mainly brachypterous (n 5 47), with the remainder macropterous (n 5 19). The adult male and female are described, and color photographs of the male and female (dorsal habitus) and hindleg (showing calcar and teeth) are included.
