Abstract
A new genus and species of Eurygeniinae: Eurygeniini (Anthicidae), Rastrogenius ambrosiaphilus Gimmel and Johnston, is described based on males and females collected from desert regions of southern California, USA. It is quite divergent within the tribe in possessing: a short, broad pronotum with no antebasal sulcus; a vertically laminate mesoventral process; the male inner protibial spur modified into a unique, rake-like organ; and a proportionally long basal piece of the aedeagal tegmen. The new genus is illustrated and compared with other genera of Eurygeniini, and a map of its geographical distribution is provided along with a checklist of all New World Eurygeniini species.
