genus Echyridella McMichael & Hiscock, 1958: cladomics
     3 Recent valid species (4 total species)

Cladomics Summary

number of species = 3 (4 total)
analyzed in 55 cladograms in 29 publications
maximum number of terminals in an analysis = 3 (mean = 1.07, median = 1)

Basic Monophyly

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