The geographical distribution of the green benthic seaweeds from the Mexican coasts of the Gulf of Mexico and the Caribbean Sea was analyzed by means of a data bank that includes 98 taxonomic publications that appeared in the 1846 - 2000 period, based on Jaccard’s index. In total, 169 species with 49 genera were recorded, with the highest species richness corresponding to Cladophora (26 species) and Caulerpa (16). Over 70.8% of all the phycoflora was confirmed based on 69 species collected by the authors in 25 localities (40.8%), and 30% through consultation of the MEXU, ENCB and DUKE herbaria. The phycological classification scheme of marine environments included 17 habitats in five coastal types where algae develop on different substrates: hard (62.5%), soft (48.4%), animal (36.8%), plant (30%), floating (11%), and artificial (12.2%). The distinction between two provinces along the Mexican coasts of the Atlantic Ocean Basin was confirmed: one corresponding to a rich tropical phycoflora along the southern coast, from Quintana Roo to Veracruz (Caribbean Province), and the other extending along the subtropical waters and being poor in species (Carolinean Province). Cabo Rojo is the boundary between the tropical and the subtropical coasts of Mexico.

We report the discovery of two wasp species emerging from egg sacs of the spider Cyrtophora citricola (Forskål 1775) collected from mainland Spain and the Canary Islands. We identify one as Philolema palanichamyi (Narendran 1984) (Hymenoptera, Eurytomidae) and the other as a member of the Pediobius pyrgo (Walker 1839) species group (Hymenoptera, Eulophidae). This is the first report of Philolema in Europe, and the first documentation of hymenopteran egg predators of C. citricola. The latter finding is particularly relevant, given the multiple invasive populations of C. citricola in the Americas and the Caribbean, where neither egg sac predation nor parasitism is known to occur. We describe rates of emergence by Ph. palanichamyi from spider egg sacs collected from the southern coast of Spain and estimate sex ratios and body size variation among males and females. We also re-describe Ph. palanichamyi based on the female holotype and male paratype specimens.

ABSTRACT In order to investigate zoogeographical patterns of the marine elasmobranch species of Colombia, species richness of the Pacific and Caribbean and their subareas (Coastal Pacific, Oceanic Pacific, Coastal Caribbean, Oceanic Caribbean) was analyzed. The areas shared 10 families, 10 genera and 16 species of sharks, and eight families, three genera and four species of batoids. Carcharhinidae had the highest contribution to shark richness, whereas Rajidae and Urotrygonidae had the greatest contribution to batoid richness in the Caribbean and Pacific, respectively. Most elasmobranchs were associated with benthic and coastal habitats. The similarity analysis allowed the identification of five groups of families, which characterize the elasmobranch richness in both areas. Beta diversity indicated that most species turnover occurred between the Coastal Pacific and the two Caribbean subareas. The difference in species richness and composition between areas may be due to vicariant events such as the emergence of the Isthmus of Panama. It is unlikely that the Colombian elasmobranch diversity originated from a single colonization event. Local diversification/speciation, dispersal from the non-tropical regions of the Americas, a Pacific dispersion and an Atlantic dispersion are origin possibilities without any of them excluding the others.

AbstractOne short-snouted spinner dolphin Stenella clymene individual stranded on the coast of Quintana Roo, Mexico, was examined for stomach and lung nematodes. During necropsy, a large number of nematodes of the species Skrjabinalius guevarai were found in the airways. Additionally, some larval Anisakis sp. were found in the stomach. Both nematode species are reported for the first time from this host. The present is the first helminthological study of the short-snouted spinner dolphin in Mexico and adjacent waters of the Caribbean Sea. S. guevarai is reported for the first time from the western Atlantic Ocean.

The collection of eight specimens of Acanthobothrium cartagenensis on the coast of Quintana Roo, México extends the geographic distribution of the species from the original locality (Cartagena, Colombia) to at least the northeastern limit of the Mexican coast of the Caribbean Sea.  The species is a parasite of Urobatis jamaicensis, a common stingray of the tropical western Atlantic.  This species has not been reported since the original description in 1980.

Parapinnixa bolagnosi new species, is described from Cubagua Island and Los Frailes Archipelago in the Caribbean Sea off Venezuela based on female specimens. The new species is distinguished from the other nominal species of the genus by having a third maxilliped with a biarticulated palp and by the absence of an exopod. The description of the genus Parapinnixa Holmes, 1894, is amended to accommodate these two distinctive characters.

British Honduras, or Belize, has a diplomatic history at once notable and obscure. Bordered by the Mexican State of Quintana Roo, the Republic of Guatemala and the Caribbean Sea, this British Colony has an area of 8,598 square miles and is thus a little larger than Wales or Massachusetts.

The presence of the species Plagiodiscus nervatus is reported for fist time in the Colombian Caribbean coastal sea. Three specimens were found, two cells in Bahia Gaira on August 2000 and 2001 in surface samples, the other cell in Bahía Chengue on May 2012 at 2 m deep. The observations showed two particular forms of the species, one with nervature and the other without it, both larger in sizes compared with those reported by other authors for the Caribbean Sea and elsewhere in the world. It is extremely important to report additional species to complement and perform inventory and lists of the species present in the area.
