genus Alasminota Ortmann, 1914: cladomics
     2 Recent valid species (2 total species)

Cladomics Summary

number of species = 2 (2 total)
analyzed in 7 cladograms in 4 publications
maximum number of terminals in an analysis = 2 (mean = 1.14, median = 1)

Basic Monophyly

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