Note D:
- Your identification is leading to a group with NO known fresh or brackish water representatives in Hawai‘i. The identification may be correct for the location where you made the collection or observation (e.g., near the ocean), but the species is marine and not covered in these keys. If the collection was made in freshwater, you should back up several couplets and confirm your decisions.
