Dufourea australis

Dufourea australis (Michener, 1937) [Holotype: CASC; ♂ San Diego (on the mesa north-east of town), California, USA; April 1, 1934] Dufourea australis is found in the xeric regions of southwestern USA and the BCP. This species specializes on pollen from yellow Asteraceae such as Bahiopsis Kellogg, Deinandra Greene, Encelia Adans., and Verbesina L. (Lincoln 1980). This species was recorded in BCS in the Cape Mountains in October 1941 (Bohart 1949). Additionally, Ayala et al. (1996) reported it in BC, but to the best of our knowledge, there are no publicly available records. See fig. 190.
