Rehderella belyaevi
Rehderella is an unusual and monotypic barnacle genus restricted to Easter Island and Pitcairn Island. Rehderella belyaevi is its only species.
Two other barnacle species are found in the intertidal zone of these islands. Euraphia devaneyi is much larger, and possesses calcareous basis. Tesseropora sp. has four shell plates with a single row of pores in shell wall. Both Euraphia and Rehderella have six shell wall plates. Rehderella differs from both in its membraneous basis and fusion of opercular plates on each side.

Range & habitat
This species is found only on Pitcairn Island and Easter Island in the uppermost intertidal and surf zone, where it forms dense colonies. Whelk predation sets lower environmental limits. During times of calm seas, colonies can be exposed to air and sun for extended periods. In this upper zone, dominance is shared by the gastropod Nodolittorina pyramidalis pascua, an algal grazer. Near the base of the barnacle zone, another grazer, Nerita morio becomes more common, along with other fauna.
