genus Diplodon Spix in Wagner, 1827: cladomics
     43 Recent valid species (43 total species)

Cladomics Summary

number of species = 43 (43 total)
analyzed in 33 cladograms in 21 publications
maximum number of terminals in an analysis = 2 (mean = 1.21, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 7
maximum number of included terminals = 2, (mean = 2 median = 2)
proportion of cladograms that support basic monophyly = 0.71
