genus Thaiconcha Bolotov, Konopleva, Vikhrev, Gofarov, Lopes-Lima, Bogan, Lunn, Chan, Win, Aksenova, Tomilova, Tanmuangpak, Tumpeesuwan & Kondakov, 2020: cladomics
     3 Recent valid species (3 total species)

Cladomics Summary

number of species = 3 (3 total)
analyzed in 32 cladograms in 20 publications
maximum number of terminals in an analysis = 3 (mean = 1.63, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 13
maximum number of included terminals = 3, (mean = 2.54 median = 3)
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.
