tribe LEOPARREYSIINI Vikhrev, Bolotov & Kondakov in Bolotov et al., 2017: cladomics
     1 genus

Cladomics Summary

number of species = 9 (9 total)
number of subtaxa (rank: genus) = 1
analyzed in 40 cladograms in 26 publications
maximum number of terminals in an analysis = 5 (mean = 2.9, median = 3)
maximum number of subtaxa (genus) = 1 (mean = 1, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 29
maximum number of included terminals = 5, (mean = 3.62 median = 3)
maximum number of subtaxa (genus) = 1 (mean = 1, median = 1)
proportion of cladograms that support basic 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.
