Remarks

The MP analysis of the data matrix corroborates previous morphological studies (Marceniuk and Menezes 2007, Marceniuk et al. 2012), both in terms of species composition and the relationship of Batrachocephalus with Ketengus plus Osteogeneiosus, which contrasts with the hypothesis of Kailola (2004),
