The rustica SPECIES group of hawaiian Drosophila (Diptera: Drosophilidae)

The rustica group, NEW SPECIES GROUP, of Hawaiian Drosophila is proposed based on unique characteristics of the male labellum and female ovipositor. The structure of the labellum is similar to the sclerotized labellum found in the closely related haleakalae species group, although additional modifications are also present. Three species are placed in this group, D. curiosa Hardy & Kaneshiro, NEW SPECIES, a new species endemic to Hawai'i, D. praesutilis Hardy, a species from O'ahu, and D. rustica Hardy, from the islands of Maui and Moloka'i.
