Micromelo guamensis is known in the Marshalls from the figured specimen found on a sandy lagoon reef at Enewetak Atoll. It was first reported in the Marshalls from Enewetak and Kwajalein Atolls by Johnson & Boucher (1984). It was previously figured as the Atlantic Micromelo undatus, but recent work by Feliciano et al (2021) shows that there are four similar species of Micromelo separated by both molecular and morphological characteristics. The crowded white spots on the body and blue/green coloration of the margin separate this species from M. scriptus.
