Subgenus Dialictus Robertson

Taxonomy: Gibbs (2010 b, 2011); Mitchell (1960).

Biology. Most species are expected to be primitively eusocial ground-nesters ( Danforth et al. 2003; Gibbs et al. 2012b), but there are a number of exceptions ( Knerer 1969; Packer 1994) and categorization of an entire species can be problematic ( Wcislo 1997). Only a small fraction have had their nesting biology studied in any detail.
