Perreault, 2014 or (Anderson, 1992)? A new coral-associated barnacle sharing characteristics of these two genera in Pacific waters (Crustacea, Cirripedia, Thoracica, Pyrgomatidae).

A new species of coral associated barnacle (Balanomorpha: Pyrgomatidae) sharing morphological features of (Anderson, 1992) and Perreault, 2014 is described. It has a fused shell and opercular plates, characteristic of . However, the morphology of the tergum and somatic body are closer to .

How do coral barnacles start their life in their hosts?

Coral-associated invertebrates are the most significant contributors to the diversity of reef ecosystems, but no studies have examined how larvae manage to settle and grow in their coral hosts. Video recordings were used to document this process in the coral barnacle Darwiniella angularis associated with the coral Cyphastrea chalcidicum Settlement and metamorphosis in feeding juveniles lasted 8-11 days and comprised six phases. The settling cyprid starts by poking its antennules into the tissue of the prospective host (I: probing stage).
