subtribe ALASMIDONTINA Rafinesque, 1820: cladomics

17 genera

Cladomics pages are experimental — even more so than the rest of this site!

The purpose of the cladomics pages for each genus and family-group level taxon is to provide statistics and references indicating the extent to which published phylogenetic work supports the classification used here.

The Cladomics Summary provides an overview of the number of studies that have included terminal species representing this taxon as well as an indication of how frequently it has been recovered as monophyletic.

Following the summary, the available published clades representing the taxon are listed.

For more information, visit the Cladomics FARQ (frequently asked rhetorical questions) page. Abbreviations for the various statistics are explained on the FARQ!

Cladomics Summary

number of species = 49 (53 total)
number of subtaxa (rank: genus) = 17
analyzed in 212 cladograms in 128 publications
maximum number of terminals in an analysis = 33 (mean = 4.28, median = 3)
maximum number of subtaxa (genus) = 15 (mean = 3.15, median = 2)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 177
maximum number of included terminals = 33, (mean = 4.93 median = 4)
maximum number of subtaxa (genus) = 15 (mean = 3.58, median = 3)
proportion of cladograms that support basic monophyly = 0.85

Rigorous Monophyly

number of cladograms that test rigorous monophyly = 130
(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 = 33 (mean = 5.28, median = 4)
maximum number of subtaxa (genus) = 15 (mean = 3.88, median = 3)
proportion of cladograms that support rigorous monophyly = 0.8
