genus Alathyria Iredale, 1934: cladomics
     4 Recent valid species (7 total species)

Cladomics Summary

number of species = 4 (7 total)
analyzed in 16 cladograms in 10 publications
maximum number of terminals in an analysis = 3 (mean = 2.13, median = 3)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 9
maximum number of included terminals = 3, (mean = 3 median = 3)
proportion of cladograms that support basic monophyly = 0

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.
