Until now, 127 species of marine sponges have been recorded in the southern Gulf of Mexico (SGoM). In this study, we describe the sponge fauna recorded on 16 coral reefs of the SGoM, defined as the Mexican waters of the Gulf of Mexico (GoM), during a period from 2005 to 2019. We report 80 sponge species, including 34 first geographic records for the southern GoM region. The latter are fully described and illustrated, taking into account 24 that represent new records for the GoM: Agelas conifera, Agelas sventres, Agelas wiedenmayeri, Prosuberites carriebowensis, Desmanthus meandroides, Cliona aprica, Cliona dioryssa, Placospongia ruetzleri, Haliclona (Gellius) megasclera, Haliclona (Reniera) aff. portroyalensis, Neopetrosia proxima, Xestospongia arenosa, Calyx podatypa, Shiphonodictyon xamaycaense, Acarnus innominatus, Iotrochota arenosa, Polymastia tenax, Svenzea cristinae, Svenzea flava, Svenzea tubulosa, Svenzea zeai, Timea stenosclera, Stellettinopsis megastylifera, Suberea flavolivescens. The present work highlights the understimated and remarkable diversity of reef-associated sponges within the Campeche Bank Coral reef systems. Present work data was compiled with existing published information to produce an updated list of 161 known sponges in the southern GoM.

AbstractSponges are one of the most conspicuous groups of epibionts in mangrove prop root habitats. However, with the exception of the Caribbean and the Indo-Pacific regions, studies focused on species diversity are lacking in other locations that have high mangrove coverage and are relatively distant from coral reef environments. Because mangrove-root epibiont communities, in general, have been understudied worldwide, this research contributes to filling this knowledge gap. In this study, a total of 30 sponge species (belonging to three subclasses, 14 families and 19 genera) were recorded as epibionts on prop roots of the red mangrove Rhizophora mangle in a tropical coastal ecosystem of the Southern Gulf of Mexico. Of these, five were new records for the Gulf of Mexico, 14 were new for the Mexican coasts of the gulf and 25 were new for the study area. Moreover, a similarity analysis based on presence/absence data of mangrove-associated sponges reported throughout the Western Central Atlantic region revealed that the sponge assemblage from the study area was more similar to those documented in most of the Caribbean locations (Jamaica, Cuba, Martinique, Panama, Venezuela, Belize and Colombia) rather than with those of the Northeast of the Gulf of Mexico, Guadeloupe and Trinidad. This relative intra-regional dissimilarity in the structure of mangrove-associated sponge assemblages may be related to differences in environmental conditions as well as taxonomic effort. The study area, unlike most of the Caribbean locations, is characterized by estuarine conditions and high productivity throughout the year. The inter-site variability recorded in the composition of mangrove-associated sponges was influenced by a set of factors such as salinity, dissolved oxygen and hydrodynamism. This study shows the importance of exploring the mangrove-associated sponge assemblages from different regions of the world as it furthers knowledge of the biodiversity and global distribution of this group.

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.

Taxonomic Studies

This study is the first inventory of ascidians from shallow waters (0–25 m) of coastal and reef habitats in the southern Gulf of Mexico where ascidian diversity is poorly known. Sampled environments in 14 locations (38 sites) with 134 samples collected from 2015 to 2017 included coral reefs, coastal lagoons, mangroves, seagrass, ports, and artificial platforms. The 31 identified species comprise 19 genera and 13 families. Ten species are newly reported in the Gulf of Mexico:AscidiapanamensisBonnet & Rocha, 2011;Ecteinascidiastyeloides(Traustedt, 1882);CystodytesroseolusHartmeyer, 1912; Eudistomaaff.amanitum Paiva & Rocha, 2018;EudistomarecifenseMillar, 1977;EuherdmaniafasciculataMonniot, 1983; Euherdmaniaaff.vitrea Millar, 1961;Polycarpacartilaginea(Sluiter, 1885);Botrylloidesmagnicoecum(Hartmeyer, 1912) andDidemnumgranulatumTokioka, 1954. Two new species will be described separately (Clavelinasp. andPyurasp.). This study provides the first records for 26 species ascidians for the region as well as describes increased distributions of ten Atlantic species. Thus, our data provide a starting point for future ecological, experimental and taxonomic studies of ascidians of the Gulf of Mexico.

There have been recent attempts to improve our knowledge about dinoflagellates of the order Dinophysales either in Mexican marine waters or worldwide, and although new records and even new species have reliable illustrations and descriptions, this group is so diverse that it needs to be studied in more detail. This paper is the product of the analysis of net phytoplankton material collected from coasts of the tropical Mexican Pacific (Gulf of California, Central Mexican Pacific and Gulf of Tehuantepec), and the southern Gulf of Mexico. Material was studied using light microscopy and scanning electron microscopy (SEM). Eleven taxa (10 species and one variety) of the section Hastata were fully identified, with nine species studied for the first time by electron microscopy (only Dinophysis hastata and D. schuettii had been previously studied by SEM), and including seven new records for the Mexican Pacific (Dinophysis monacantha, D. nias, D. phalacromoides, D. pusilla, D. swezyae, D. uracantha var. mediterranea, and D. uracanthoides), and one new record for the Gulf of Mexico (Dinophysis uracanthoides). Two species remain as unidentified, as only one specimen of each was found. Additionally, we studied in detail the new species, Dinophysis conjuncta sp. nov., for which a full description is provided. Descriptions, measurements, illustrations and local distribution data are provided for each species.

Studies on epiphytic diatoms can be considered somewhat lacking worldwide, mainly because of the enormous scientific research potential around them, and there is still much to do concerning floristics alone. Particularly for the Mexican coasts, mainly in the southern Gulf of Mexico. Thus, our objective was to determine the epiphytic diatom floristics for several species of Rhodophyta from the coast of Veracruz state (México). Diatoms sampled from specimens of six taxa of Rhodophyta were observed in permanent mountings, under light microscopy. A total 115 diatom taxa were identified, that support our expectancy of a potential species richness much higher on red algae hosts. A presence absence similarity measurement suggested that a single diatom assemblage was hosted in the six red algae taxa. The species composition is highly similar to epiphytic diatom assemblages from NW Mexico, albeit six taxa are new records for Mexican littorals. A photographic catalog of the identified epiphytic diatoms is provided.Florística prospectiva de diatomeas epifitas sobre Rhodophyta en el Sur del Golfo de México Los estudios sobre diatomeas epifitas a nivel global se pueden considerar escasos, principalmente por el gran potencial científico que representan. Una consecuencia de ello es lo mucho que falta por hacer tan solo en florística a lo largo de las costas mexicanas, particularmente al sur del Golfo de México. Así, el objetivo de nuestro estudio fue determinar la florística de diatomeas epifitas en varias especies de Rhodophyta de la costa del Estado de Veracruz, México. Se identificaron diatomeas epifitas en talos de seis taxa en preparaciones permanentes bajo microscopía de luz. La lista florística de diatomeas redituó 115 taxa, lo que respalda nuestra expectativa de una riqueza de especies potencial mucho mayor en Rhodophyta hospederos. La similitud (Bray-Curtis) con base en presencia/ausencia de taxa sugiere que una sola asociación de diatomeas epifitas se distribuye entre los seis taxa de algas rojas hospederos. La composición de especies es muy similar a la de asociaciones de diatomeas epifitas del NW de México, aunque seis taxa son nuevos registros para litorales mexicanos. Se incluye un catálogo fotográfico de los taxa de diatomeas epifitas identificadas.
