genus Velesunio Iredale, 1934: cladomics
     5 Recent valid species (5 total species)

Cladomics Summary

number of species = 5 (5 total)
analyzed in 56 cladograms in 35 publications
maximum number of terminals in an analysis = 3 (mean = 1.23, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 11
maximum number of included terminals = 3, (mean = 2.18 median = 2)
proportion of cladograms that support basic monophyly = 0.09

Pairwise Cladogram Clustering

The graphs below depict in two dimensions all pair-wise ingroup distances within the cladome. See the Cladmoics FARQ for more information.
