The material from Rapa Nui is somewhat problematic. In most specimens, chelipeds are lost or are detached but present in the vial. The largest specimen, a female (cl 8.0 mm) has no chelipeds; however, two equal and subsymmetrical chelipeds matching her size are present in the vial; one of them is illustrated (
