subfamily VELESUNIONINAE Iredale, 1934: cladomics
     6 genera

Cladomics Summary

number of species = 17 (23 total)
number of subtaxa (rank: genus) = 6
analyzed in 62 cladograms in 37 publications
maximum number of terminals in an analysis = 7 (mean = 2.31, median = 1)
maximum number of subtaxa (genus) = 5 (mean = 1.84, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 26
maximum number of included terminals = 7, (mean = 4.12 median = 3)
maximum number of subtaxa (genus) = 5 (mean = 3, median = 2)
proportion of cladograms that support basic monophyly = 0.69

Rigorous Monophyly

number of cladograms that test rigorous monophyly = 25
(Rigorous monophyly refers to cladograms with terminal species representing more than one subtaxon (genus) taxon and at least one rigorous outgroup (family).
maximum number of included terminals = 7 (mean = 4.2, median = 3)
maximum number of subtaxa (genus) = 5 (mean = 3.08, median = 2)
proportion of cladograms that support rigorous monophyly = 0.68

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.
