Four new species of the Drosophila onychophora species group (Diptera, Drosophilidae) in the Parque Arqueológico Rumipamba, Pichincha, Ecuador

Abstract:

The species of the subgenera Phloridosa and Drosophila (in this last one, regarding the Drosophila species groups: D. flavopilosa, D. onychophora and D. bromeliae) are species of Drosophila that developed only in flowers. The group D. onychophora was proposed to bring together exclusively antophilic species. The former group is composed by 18 species, and is associated to flowers of Asteraceae. Captures were made in the Parque Arqueológico Rumipamba, Pichincha, Ecuador, during February, May, July, September and December of 2009. The species were collected directly from flowers with an insect aspirator. A total of 427 individuals from Drosophila were captured. We identified 11 species, of which six are new species of the D. onychophora species group and one is a new record for Ecuador. In this paper we describe four of the six new species.
