摘要

Records are given for 15 Scaphisomatini species captured by V-flight intercept traps in Arizona. Baeocera hamata Lobl & Stephan, B. nana Casey and Toxidium gammaroides LeConte are recorded for the first time from Arizona, B. arizonensis sp. nov., B. obscura sp. nov. B. vintercepta sp. nov. and Scaphisoma declivum sp. nov. are described as new. Scaphisoma dakotanum Fall is synonymized with S. desertorum Casey. The aedeagi of Scaphisoma desertorum Casey, S. rufulum LeConte, and S. rubens Casey are illustrated for the first time. A key to the Arizona species of Scaphisoma Leach is provided. A new iteration of the V-flight intercept trap is described and the diversity of Arizona Scaphisomatini is discussed.
