Molecular phylogenetic studies have made an important contribution in corroborating the monophyly of some groups recognized in previous systems [2].
(2010) upheld the monophyly of Loranthaceae, with the Schoepfiaceae and Misodendraceae families as sister groups.
We found no consistent support for reciprocal monophyly between the Yaqui and Sinaloa catfishes, but this possibility was not rejected by the analysis.
Monophyly of Aporocotylidae was not supported; however, those aporocotylids infecting principally marine and estuarine bony fishes clearly were monophyletic.
Monophyly of both clades is well supported by maximum parsimony, maximum likelihood and Bayesian analyses (CHATROU et al., 2012).
The next branch with several (13) synapomorphies (85), (22-1), (25-3), (30-2), (32-7), (35-2), (36-4), (37-5) (383), (39-2), (40-2), (42-2), and (47-1) indicates the monophyly of Corixoidea.

They also note that this provides strong evidence for arachnid monophyly and a single shared terrestrial arachnid ancestor.
Notably, support for enteropneust monophyly is moderate (65/0.99), and SH testing did not reject the alternative hypothesis (enteropneust paraphyly).
lupus demonstrated that North America, Europe and most of Asia populations represent a single mega-ESU, showing reciprocal monophyly with allopatric distributions.
Monophyly of the genus Osteopilus is supported by a 93% bootstrap value and a 0.99 posterior probability, although the relationships among species are not fully resolved (Fig.
