}}Broiliellus is an extinct genus of dissorophoid temnospondyl within the family Dissorophidae. Broiliellus is most closely related to the genus Dissorophus, and both have been placed in the subfamily Dissorophinae. Broiliellus is known from three species from the Early Permian: the type species Broiliellus texensis and the species Broiliellus brevis and Broiliellus olsoni. A fourth species, Broiliellus novomexicanus, which was originally named Aspidosaurus novomexicanus, is now thought to fall outside the genus as a member of the subfamily Cacopinae.[1] PhylogenyThe phylogenetic analysis of Schoch (2012) found that Broiliellus was most closely related to Dissorophus. However, the three species of Broiliellus did not form their own clade, but rather a polytomy (unresolved evolutionary relationship) with Dissorophus.[1] Holmes, Berman & Anderson (2013) named a new species of Broiliellus, Broiliellus reiszi. They performed two phylogenetic analyses using the data matrix of Schoch (2012). In the second analysis the codings for "B." novomexicanus (i.e. Rio Arriba taxon) were not modified. This analysis yielded more resolved topology and a monophyletic Broiliellus with the exclusion of "B." novomexicanus.
