Research Project: REVSYS: PHYLOGENY AND SYSTEMATICS OF THE MEGACHILIDAE
2009 Annual Report


1a.Objectives (from AD-416)
To produce a phylogenetic framework for the bee family Megachilidae, a generic/subgeneric framework for the tribe Anthidiini (carder and resin bees), revise the largest genera of this tribe, and develop a web-based digital library of the results. Revisions of important pollinators in the family Megachilidae adn their cleptoparasites will be produced. Web-based identification guides for the Anthidiini will be produced to aid pollination research.


1b.Approach (from AD-416)
A combined molecular and morphological analysis of relationships across the family Megachilidae and within the tribe Anthidiini will be used to develop well supported phylogenies. Revisionary studies at the species level will utilize standard systematic methodologies. Web-based keys will be generated using existing software (e.g. Lucid, DiscoverLife) that are well illustrated using close-up images generated with imaging software.


3.Progress Report

The bee family Megachilidae (resin, carder, leafcutter, and mason bees) includes most of the non-honey bee managed pollinators. To better utilize the pollination potential of this large and diverse family of bees a stable classification is needed combined with revisionary studies to define the species and characterize their biological traits. Emphasis in this project is on the classification of the family, and revisions of many of the genera of carder and resin bees (tribe Anthidiini). A family tree for Megachilidae using molecular data from multiple genes has been produced. A post-doc has been hired to revise the largest genus in this group (Anthidium) and the most broadly distributed. A revision of the approximately 80 Western Hemisphere species is nearly completed. It includes a number of new species. The ADODR monitored the progress on this project through various methods including telephone conference calls, site visits, and meetings to discuss project plans and accomplishments, validate project expenditures, and provide technical advice.
