tribe CASTALIINI Morretes, 1949: cladomics
     3 genera

Cladomics Summary

number of species = 17 (17 total)
number of subtaxa (rank: genus) = 3
analyzed in 39 cladograms in 25 publications
maximum number of terminals in an analysis = 5 (mean = 1.41, median = 1)
maximum number of subtaxa (genus) = 3 (mean = 1.26, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 6
maximum number of included terminals = 5, (mean = 3.67 median = 3.5)
maximum number of subtaxa (genus) = 3 (mean = 2.67, median = 3)
proportion of cladograms that support basic monophyly = 1

Rigorous Monophyly

number of cladograms that test rigorous monophyly = 5
(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 = 5 (mean = 3.8, median = 4)
maximum number of subtaxa (genus) = 3 (mean = 2.8, median = 3)
proportion of cladograms that support rigorous monophyly = 1

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.
