genus Neotrigonia Cossmann, 1912: cladomics
     8 Recent valid species (12 total species)

Cladomics Summary

number of species = 8 (12 total)
analyzed in 97 cladograms in 48 publications
maximum number of terminals in an analysis = 3 (mean = 1.42, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 36
maximum number of included terminals = 3, (mean = 2.14 median = 2)
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.
