Missing data can be problematic in phylogenetic analyses (e.g.[3][4][5][6]) and lead to erroneous conclusions about systematic relationships.

Additionally, there is no mention of checking for base-composition bias amongst taxa (non-stationarity), which can also lead to incorrect tree phylogenies (e.g.[7][8]).

[10] The AmphibiaWeb also recognizes Cyclorana,[10] a position that, without additional amendments, renders Ranoidea paraphyletic; it may be treated as a subgenus.

Many species have tadpoles that develop in mountain streams and have enlarged ventral mouths.

[11] The following species are recognised in the genus Ranoidea:[1] Although currently listed as incertae sedis, it is expected that "Ranoidea papua" (Van Kampen, 1909) will also be included in the genus once its range has been properly delimited.
