Studies in Hawaiian Diptera I: New Distributional Records for Endemic Asteia (Asteiidae)

Abstract. New island records are reported for five species of Asteia endemic to the Hawaiian Islands (Asteia hawaiiensis, Asteia mauiensis, Asteia molokaiensis, Asteia palikuensis, Asteia sabroskyi). These new records expand our understanding of distributions in Asteia, change the percentage of single island endemics from 78% to 33%, and have significance in how we view the process of diversification acting in this lineage. We also present a list of the known rearing records for two species in this group. Asteia montgomeryi has been recorded from Erythrina and Asteia sabroskyi has been reared from Pisonia, Urera, Charpentiera and Hibiscadelphus.
