About Solidobalanus hawaiensis
Solidobalanus hawaiensis (Pilsbry, 1916) is a marine acorn barnacle. The accepted spelling hawaiensis is supported by WoRMS and ITIS; the former Atlas spelling hawaiiensis is retained only as a search alias. Coles et al. (2004), Bishop Museum Technical Report 29a, printed page 123, listed the species under its historical combination Balanus hawaiensis in the Present Study row at KA4, Port Allen reef, Kauaʻi. That original table documents a 2002 survey attribution, but no corresponding KA4 specimen was reexamined for this Atlas account. Hosie (2024) diagnosed S. hawaiensis using museum material from the Indian Ocean: six white solid shell-wall plates, reddish-orange radii, external longitudinal ribs, and a relatively narrow tergum. Those characters guide the reconstruction and help separate the species from similar barnacles; the museum specimens do not establish the appearance or substrate of the KA4 animal. The Kauaʻi survey row identifies no precise attachment substrate, depth, size, diet, reproduction, population trend, or current occupancy. This record preserves the historical KA4 report and its original name while distinguishing its unverified specimen identity and present-day status from the accepted taxonomic name.

- Seasonal description
- Coles et al. (2004, p. 123) reported Balanus hawaiensis at KA4, Port Allen reef, in its Kauaʻi survey. The accepted combination is Solidobalanus hawaiensis (Pilsbry, 1916). The original KA4 identification has not been independently rechecked against a specimen, and the survey does not establish current abundance or persistence.
