A new species of the Drosophila tripunctata group (Diptera: Drosophilidae) associated with fallen flowers of six Lecythidaceae species in the Amazon Rainforest.

The tripunctata group falls under the subgenus Drosophila Falln, 1823 of the genus Drosophila Falln, 1823, and is composed of four subgroups and 17 species not assigned to subgroups. This group is widely distributed throughout tropical regions and is predominantly found in preserved forest environments. With a predicted high number of cryptic species, the occurrence of intraspecific morphological polymorphisms made it difficult to establish lines in the laboratory.
