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.

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 Species

Gonolobus is reassessed in the Yucatan Peninsula Biotic Province (YPBP). The genus consists of seven taxa in the area: six species and two subspecies. These include a taxon that we propose here as a new species and the treatment of G. yucatanensis as a subspecies of G. stenanthus and the new combination G. stenanthus subsp. yucatanensis is proposed. These two taxa are endemic to the YPBP. The other species are G. barbatus (for which we propose a lectotype), G. cteniophorus, G. fraternus, G. glaberrimus, and G. leianthus. The new species is G. caamalii Carnevali & R. Duno, restricted to the Yucatán state in Mexico and distinguished by its corolla lobes with a dark purple (almost black) longitudinal, callose band along the proximal 2/3 on the right side of the lobes and a 1.1–1.3 mm broad, annular, continuous dark purple-black band surrounding the gynostemium and corona at the base of the corolla lobes. It appears related to G. leianthus from southern Megamexico, a species from humid forests at higher elevations and that differs in its larger flowers with broader corolla lobes and a strikingly different color pattern in the flowers. The new species is described, illustrated, and discussed. Entries for all Gonolobus species from the YPBP include a brief discussion and specimen citations. The conservation status of the Gonolobus taxa endemic to the YPBP are assessed either as as Endangered (EN) or as Near threatened (NT). Distributional maps for all Gonolobus from the area covered are presented. Finally, we offer a key to Gonolobus of the YPBP.

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.

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.

A taxonomic checklist of sublittoral tanaidaceans from the north coast of the Yucatan Peninsula, southern Gulf of Mexico, is presented in this study; it includes notes on geographic distribution, habitat, and an identification key. The genus Cacoheterotanais and the species Cacoheterotanais rogerbamberi, Mesokalliapseudes macsweenyi, Pagurotanais largoensis, Parakonarus juliae, and Psammokalliapseudes granulosus have their known distribution range within the Gulf of Mexico expanded, and are considered new records; this increases the number of tanaidacean species to 23 for the southeastern Gulf, and to 87 for the entire Gulf of Mexico.
