Abstract>

Three species are recognized in the North American genus Megetra LeConte. The most distinctive of these anatomically and ecologically is M. cancellata (Brandt and Erichson), which ranges discontinuously from Arizona and New Mexico to the state of Hidalgo in México and occurs in limited sympatry with both of its congeners. Megetra vittata (LeConte) ranges from northern Arizona to western Texas. It appears to be strictly allopatric with, and similar ecologically to, M. punctata, new species, which ranges from southern Arizona and New Mexico to Durango, México. Specific diagnoses are made on the basis of characters of adult and, for M. cancellata and M. punctata, larval anatomy. Intraspecific variation in several adult characters is analyzed. Notes on the seasonal distribution, habitat, and behavior of the adult beetles are included.
