This study was directed to analyze the monophyly of the family and the groups within it. Thirty-three taxa of Balanidae, 9 of Archaeobalanidae, 3 of Pyrgomatidae and 2 of Balanomorphoidea were used in the analysis. Anatomical aspects of soft and hard parts provided 70 characters.

The strict consensus tree showed that Pyrgomatidae is the sister group of Balanidae. The genus Balanus appears in different clades and therefore it is non-monophyletic. Striatobalanus appears within Balanidae close to the clade formed by Megabalaninae and Concaviinae. The \"Balanus amphitrite\" group (sensu Newman, 1976) with Tetrabalanus and Fistulobalanus form a monophyletic group.
