Abstract

The subgenus Chalepochile Gonzalez & Engel of Megachile Latreille was known only from males of two species. In this contribution the female of M. ardua Mitchell, type species of Chalepochile, is described, as well as a new species based on both sexes. The new species M. (Chalepochile) bilineata occurs in the provinces of Córdoba, La Rioja and Mendoza in Argentina. The phylogenetic relationships of the subgenus Chalepochile are discussed in the light of characters of the females.
