Other Notes

More study with complete taxon sampling, many specimens from all over the Caribbean, and for multiple genes are required to determine just how many “species” of Hypoplectrus actually occur in the Caribbean Sea. The species are morphologically almost identical, and have weak genetic signatures indicating a recent radiation.
