Bivalvia | Venerida | Cyrenoidea

family CYRENOIDIDAE H. & A. Adams, 1857 (1853): cladomics
     5 genera

Cladomics Summary

number of species = 38 (38 total)
number of subtaxa (rank: genus) = 5
analyzed in 3 cladograms in 1 publication
maximum number of terminals in an analysis = 7 (mean = 4.33, median = 4)
maximum number of subtaxa (genus) = 4 (mean = 3, median = 4)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 3
maximum number of included terminals = 7, (mean = 4.33 median = 4)
maximum number of subtaxa (genus) = 4 (mean = 3, median = 4)
proportion of cladograms that support basic monophyly = 0.67

Rigorous Monophyly

number of cladograms that test rigorous monophyly = 2
(Rigorous monophyly refers to cladograms with terminal species representing more than one subtaxon (genus) taxon and at least one rigorous outgroup (family).
maximum number of included terminals = 7 (mean = 5.5, median = 5.5)
maximum number of subtaxa (genus) = 4 (mean = 4, median = 4)
proportion of cladograms that support rigorous monophyly = 0.5
