The Sabellariidae has been scarcely studied in the Gulf of Mexico and the Caribbean Sea, and there are 18 species recorded out of 140 species known in the world. This work aims to improve the knowledge of the sabellariids in the northwestern tropical Atlantic region, provide standardized descriptions, and generate taxonomic identification keys. Sabellariids from three scientific collections were revised: Reference Collection of Laboratorio de Poliquetos, El Colegio de la Frontera Sur (ECOSUR), Chetumal, Collection of Laboratorio de Biodiversidad y Cambio Climático, ECOSUR, Campeche and Invertebrate Zoology Collection of Florida Natural History Museum, University of Florida, Gainesville. Three new species are described: Idanthyrsus bastidai n. sp. and I. mikeli n. sp. from Venezuela, and Sabellaria salazari n. sp. from the Yucatán Peninsula. In addition, new records of S. floridensis Hartman, 1944, S. vulgaris Verrill, 1873, and Phragmatopoma caudata Krøyer in Mörch, 1863 are provided.

Pseudonereis gallapagensis Kinberg, 1865 and P. variegata (Grube & Kröyer in Grube, 1858) are the only two species of this genus commonly recorded along Atlantic American coasts, but their type localities are in the Eastern Pacific, and their morphology differs. Two new Pseudonereis species are described from Eastern Mexico: P. brunnea sp. n. from the Gulf of Mexico, and P. citrina sp. n. from the Caribbean Sea, previously confused with P. gallapagensis. In order to facilitate comparisons, descriptions based on specimens from near the type locality for P. gallapagensis (Peru and Ecuador), and topotypes for P. variegata (Valparaiso, Chile), are included. Based on these comparisons and current descriptions, the synonymies of Nereis ferox Hansen, 1882 described from Brazil with P. variegata, and of Pseudonereis formosa Kinberg, 1865 described from Hawaii with P. gallapagensis, are rejected. Consequently, both are regarded as distinct species and revised diagnoses are provided for them. The record of P. ferox from the Gulf of Guinea proved to be an undescribed species, and is herein described as P. fauveli sp. n. The number of paragnath rows in nereidid pharynx areas VII–VIII has been interpreted in several ways, leading to confusion; an alternative method to determine the number of bands and rows is proposed. The midventral region, the division of areas VII–VIII in furrow and ridge regions, and the description of the arrangement based on the pattern of paragnaths in such regions, are proposed. Further, the terms shield-shaped and pointed (P-bars) bars are redefined, and a new term, crescent-shaped bars, is proposed for paragnaths in the areas VI in some Pseudonereis and Perinereis species. A key for all Pseudonereis species is also included.

Three New Species

Species and genera of Bairdiidae can be difficult to discriminate, because of the somewhat limited morphological range of the carapace and limbs and the prevalence of homeomorphy. Attention to the esophageal flapper valve, an uncalcified but relatively well sclerotized structure, may contribute to more reliable identifications. Living species of Neonesidea exhibit sufficient variability in the architecture of this structure to suggest that it may have taxonomic value. Twelve named and three new species are examined to test this premise: N. bacata, N. caraionae n. sp., N. decipiens, N. credibilis n. sp., N. forea n. sp., N. edentulata, N. gerda, N. holdeni, N. longisetosa, N. manningi, N. mediterranea, N. omnivaga, N. plumulosa, N. schulzi, N. tenera. The geographic range of N. gerda is extended across the Gulf of Mexico, while the ranges of N. longisetosa and N. dinochelata are restricted. This supplemental information helps to clarify the relationships of several poorly known species from carbonate environments of Bermuda, the Bahamas, Florida, the Gulf of Mexico, and the Caribbean.

An emerging ulcerative skin disease in invasive lionfish in Florida and Caribbean Sea is being tracked. Diseased lionfish were first reported in summer 2017 from the northern Gulf of Mexico with additional reports in 2018. Florida Fish and Wildlife Conservation Commission,  University of Florida, and other fish health scientists are investigating this disease, but initial evaluations have not yet identified a cause.  More advanced diagnostics are underway to better understand the factors causing this disease/syndrome and its potential to spread to other species. Researchers are also examining the lethal and chronic effects of this disease on individual fish, as well as its effect on lionfish populations, the lionfish fishery, and reef fish communities. Researchers and Extension Personnel (IFAS/SeaGrant) are asking stakeholders to report and document any ulcerated or otherwise diseased lionfish in FL and the Caribbean.

Six species of hermit crabs of the family Paguridae from the Caribbean Sea and Gulf of Mexico region, including two new species, Anisopagurus asteriscus sp. nov. and Pagurus alarius sp. nov., are documented. The two new species are described, and recognition characters summarized for the four previously known species. Reports of the latter, Nematopaguroides fagei Forest & de Saint Laurent, 1968, N. karukera Lemaitre, Felder & Poupin, 2017, Paguriscus robustus Lemaitre, Felder & Poupin, 2017, and Pylopaguridium markhami McLaughlin & Lemaitre, 2001, represent range extensions for all four species. Color photographs are included for four of the species, as well as remarks on their taxonomy and distributions. All six species included can be categorized as micro-pagurids (with shield length rarely exceeding 2.0 mm), and were collected from cryptic reef habitats in Bocas del Toro, Panama; the French Antillean island of Guadeloupe; and the Gulf of Mexico coasts of Louisiana, Yucatán, and Florida Keys. The discovery of these new or rare species supports the conclusion of recent studies that the diversity of pagurids from the Caribbean region has yet to be fully realized.

A New Species

Gracilaria falconii from Falcón, Venezuela, is described as a new species, based mainly on phylogenetic evidence. Morphologically, G. falconii is similar to G. mammillaris, a species previously reported from the Gulf of Mexico, the Caribbean Sea, Venezuela, and Brazil. Although G. falconii is morphologically different from phylogenetically closely related species, morphological boundaries between G. falconii and other flattened Gracilaria are not so clear.

Abstract: Seven species of terrestrial isopods are recorded from the coasts of the Pacific and Caribbean sides of Costa Rica. Three species (Buchnerillo neotropicalis, Hawaiioscia nicoyaensis and Trichorhina biocellata) are described as new and two species (Tylos niveus and Armadilloniscus cf. caraibicus) are newly recorded from the country. The poorly known species T. niveus is also illustrated. At present the total number of terrestrial isopod species recorded from Costa Rica is 30. Interestingly four typical littoral halophilic species (Ligia baudiniana, Tylos wegeneri, T. niveus and A. cf. caraibicus) are present on both the Pacific coast of Costa Rica and on the coasts of the lands encompassed by the Caribbean Sea. With the sole exception of A. cf. caraibicus, no morphological differences could be detected from the Pacific and Caribbean populations of those species. Rev. Biol. Trop. 66(Suppl. 1): S187-S210.

Squat Lobsters

The genus Munidopsis is one of the most diverse genera within squat lobsters. Here, three new species of Munidopsis, M. cornuata n. sp., M. senticosa n. sp., and M. turgida n. sp., from <500 m off Guadeloupe Island (Caribbean Sea), are fully described and illustrated. Among the Atlantic species of the genus, M. cornuata n. sp. belongs to the group of species having the dorsal surface of the carapace with spines and is most similar to M. robusta (A. Milne-Edwards, 1880), from the Gulf of Mexico and Caribbean Sea. Munidopsis senticosa n. sp. resembles M. barbarae (Boone, 1927) from the Bahamas and the Gulf of Mexico and M. penescabra Pequegnat & Williams 1995, from off Georgia and Gulf of Mexico; the three species belong to the group having the carapace covered with sharp spines. Finally, M. turgida n. sp. is characterized by having the dorsal surface of the carapace, abdomen and pereiopods covered by granules; and resembles M. granulens Mayo, 1972, from NW Caribbean Sea. Apart from the morphological evidence, the analysis of mitochondrial genes (COI and 16S) supports establishing these new species, showing very high genetic divergences compared to their congeners (from 14.5 to 17% for COI, and 7.7 to 12.8% for 16S data).

Three New Species

Three new species of Pista are described. Pista vossae sp. nov., occurs from Florida to Jamaica and Venezuela.This species is distinguished by uncini having few teeth, and base shaped with a rounded anterior process. Pistalizae sp. nov., is present in Florida, the Gulf of Mexico and Panama. This species is distinguished by having a lobeon the dorsal edge of segment 4, eyespots, and uncini with long posterior processes on the anteriormost threeuncinigers only. Finally, Pista hataam sp. nov., from Yucatan Basin, is distinguished by having two lobes on thedorsal edge of segment 4, separated by a smooth swollen membrane, and all thoracic uncini with long posteriorprocesses. Thus, the number of species of Pista for the region is doubled to six. A taxonomic key for Caribbean species is provided.
