A new bot fly species of Cuterebra (Diptera: Oestridae) from Ecuador

A new species of cuterebrine rodent bot fly, Cuterebra yanayacui sp. nov., is described from the cloud forest of Ecuador, and it is argued that the species mimics a range of aculeate hymenopterans, including euglossine orchid bees of the genera Eufriesea Cockerell and Eulaema Lepeletier and bumble bees of the subgenus Cullumanobombus Vogt. Montemyia bureni Dalmat, 1942 is proposed as a junior synonym of Cuterebra ornata Bau, 1928, syn. nov., and an updated identification key to the species of the Metacuterebra species group within Cuterebra Clark is provided. The 5'-end of the Cytochrome c oxidase subunit I gene is sequenced for the new species and compared with published Cuterebra sequences.
