Abstract

The genus Renilla is an interesting taxon for phylogenetic studies, which includes six species endemic to America with an anphiamerican distribution (Pacific–Atlantic Ocean). A cladistic analysis of Renilla Lamarck, 1816 using eight characters from external morphology produced one cladogram (length 14, CI = 0.92, RI = 0.87), and the characters were polarized using Echinoptilum macintoshii Hubrecht, 1885 as an outgroup. In the cladogram the following phylogenetic sequence results: ((R. koellikeri (R. muelleri, R. musaica)) (R. octodentata (R. reniformis, R. tentaculata))).
