AbstractAlthough the genusGracilariais well represented on the Mexican coasts, there are few studies focused on the taxonomic aspects and the clarification of the relationships between species. The high morphological plasticity exhibited by several of its representatives could underestimate the true species richness. In the present study, a group of cylindrical specimens ofGracilariafrom the southeastern Gulf of Mexico, previously identified asG. cornea, was collected. Based on COI-5P andrbcL sequences, these samples formed an independent group closely related toG. ferox, a flat species. Morphologically, our specimens differed fromG. feroxand the other species ofGracilariaby the presence of very small cystocarps and a thick pericarp composed of many layers of cells. We proposeGracilaria microcarpasp. nov. as the name for this group of cylindrical specimens from the Yucatan Peninsula of Mexico.

A new subspecies of Scaphella junonia has been discovered off the Alacranes Reefs, along the northernmost edge of Campeche Bank, Yucatan Peninsula of Mexico. The new subspecies, here named Scaphella junonia curryi, differs from the other four known S. junonia subspecies in having the narrowest and most elongated shell, having the strongest and most extensive ribbed sculpture on the spire whorls, and in having a different color pattern composed of very large, almost fused rectangular spots. The new subspecies is confined to the edge of the Campeche Escarpment off the northern Campeche Bank islands and reefs.

A large river turtle Dermatemys mawei, found only in the coastal lowlands of the Gulf of Mexico, is becoming rare throughout most of its restricted range. It is found from central Veracruz, Mexico, eastward through Guatemala and Belize, but not in the Yucatan Peninsula, and it is heavily hunted for its meat. The only living representative of the Dermatemydidae, a turtle family known from as early as the Cretaceous, its closest living relatives are the mud turtles (Kinosternidae), and it is not as closely related to the snapping turtles (Chelydridae) as previously thought.4,5,9,20 In the latest classification of turtles the Dermatemydidae are placed in the Superfamily Trionychoidea of the Infraorder Cryptodira.

Reef Monitoring

Autonomous reef monitoring structures (ARMS) have been proposed as a standardized, passive, nondestructive sampling tool. This study assessed the ability of ARMS to capture the cryptic species diversity of two coral reefs by recording species richness and taxonomic representativeness using conventional taxonomy. The capacity of ARMS, as artificial substrates, to favor the establishment of nonindigenous species over native species was also evaluated. The use of ARMS allowed the detection of 370 species morphotypes from nine phyla, yielding 13 new records of geographic distribution expansion, one exotic species for the Gulf of México and the Caribbean Sea, and six newly described species. It was also possible to make spatial comparisons of species richness between both reefs. ARMS captured cryptic diversity exceptionally well, with the exception of echinoderms. Furthermore, these artificial structures did not hinder the colonization ability of native species; in fact, the colonization patterns on the structures themselves represented the spatial differences in the structure of benthic assemblages. This study represents the first effort to make a conventional taxonomic description of the cryptic fauna of the Yucatan Peninsula using ARMS. It is recommended to assess coral reef species diversity, but more taxonomists specialized in marine invertebrates are needed.

The Mardi Gras wrasse, Halichoeres burekae, is a planktivorous fish considered to be endemic to the Gulf of Mexico and recently described. It was previously known only from the Flower Gardens Banks National Marine Sanctuary (USA) and Veracruz, (Mexico). We recorded Halichoeres burekae (initial female [50–70 mm TL] and terminal male [60–90 mm TL] phases) in the Alacranes Reef, a reef platform located off northern Yucatan Peninsula, southern Gulf of Mexico. This fish is relatively common in shallow (2 m) and deep (25 m) waters in the Alacranes Reef, where it forms small (15 individuals) to large (200 individuals) aggregations. This record represents a range extension for H. burekae and indicates a general lack of knowledge about the southern Gulf of Mexico reef fish fauna.
