subfamily MONOCONDYLAEINAE Modell, 1942: cladomics
     6 genera

Cladomics Summary

number of species = 18 (18 total)
number of subtaxa (rank: genus) = 6
analyzed in 42 cladograms in 24 publications
maximum number of terminals in an analysis = 5 (mean = 1.19, median = 1)
maximum number of subtaxa (genus) = 3 (mean = 1.14, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 5
maximum number of included terminals = 5, (mean = 2.6 median = 2)
maximum number of subtaxa (genus) = 3 (mean = 2.2, median = 2)
proportion of cladograms that support basic monophyly = 0.2

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 = 2.6, median = 2)
maximum number of subtaxa (genus) = 3 (mean = 2.2, median = 2)
proportion of cladograms that support rigorous monophyly = 0.2

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.
