33 spp. in 2 genera of 2 tribes in our area, >1000 spp. in 16 genera of 4 tribes worldwide/total(1)
worldwide; our tribes are both cosmopolitan, one tribe is palaeotropical, and another one (of 3 spp. only) is restricted to the Andean region(1)
Many Xylocopinae are primitively eusocial(2)
Each of our two genera is the only member of its own tribe (Ceratinini and Xylocopini, respectively)(1)
Recent molecular phylogenetic studies resolving this subfamily as paraphyletic due to a divergent position of the Chilean tribe Manueliini can be interpreted as failure of commonly used phylogenetic methods to achieve a credible result.
