Nine of the sixteen species of the western Atlantic genus Hypoplectrus (Serranidae) are currently recognized to be distributed in the Gulf of Mexico. Hypoplectrus atlahua n. sp. is only known from Tuxpan banks and Isla Lobos, Veracruz. It differs from the only other similarly colored species, H. nigricans (i.e black hamlet) in the number of gill rakers on the first arch, snout length, upper jaw length, pectoral and pelvic fins lengths, and coloration. It is a dark brown species, lacking nose spots, mask, caudal fin dark spots, peduncle saddle, and pectoral pigmentation, but has iridescent violet speckles and lines on cheeks and chest, and also a well-defined but rather small violet dot over the dorsal flat spine on the rear edge of the opercle.
