摘要

摘要根据美国南加州沙漠地区采集到的Eurygeniini(蚁科)、Rastrogenius ambrosiaphilus Gimmel和Johnston的雌雄记述了Eurygeniini(蚁科)一新属和新种。在部落内部，它在以下方面是相当不同的:有一个短而宽的前额，没有前基底沟;垂直层状中腹突;雄的内胫骨刺修饰成一独特的，耙状的器官;和一个成比例的长被被基部。对新属进行了图解，并与其他属进行了比较，并提供了其地理分布图以及所有新世界Eurygeniini种的清单。

A Morphologically Divergent New Genus and Species of Eurygeniinae from California, USA (Coleoptera: Anthicidae)

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.
