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.

Delayed Recognition

The barnacle Megabalanus zebra is largely known from ship hulls, with little information on its biology, ecology, and natural range. We identify M. zebra here from the southern Caribbean, based upon specimens collected as early as 2002. Challenges associated with identifying megabalinine species have delayed recognition of this species as distinct from other Caribbean Megabalanus. Sequenced material of M. zebra from Curaçao did not match M. zebra GenBank sequences that could be verified by descriptions or vouchered material. The presence of young M. zebra on vessels that have not left the Caribbean, as well as on pier pilings and resident buoys, indicate that this species is established in the tropical Western Atlantic Ocean, but the timing of its invasion remains unknown.

Paired End Sequencing

As a first step to establish the genetic structure of the sea urchin Echinometra lucunter lucunter throughout the Caribbean Sea, 26 microsatellite loci were isolated using Illumina paired-end sequencing, Next Generation Sequencing (NGS). We successfully optimized 17 loci for genotyping and the variation tested for 23 individuals from the Caribbean Sea and Tropical Eastern Atlantic Ocean. The allele number per locus (Na) ranged from four to 24, the observed heterozygosity (Ho) from 0.682 to 1, and the expected heterozygosity (He) from 0.609 to 0.9304. We detected no linkage disequilibrium between pairs of loci. These microsatellites will be used for the first time to detect the influence of marine barriers to genetic flow in the sea urchin E. lucunter lucunter throughout the Caribbean Sea. These new validated markers will be essential for current conservation and connectivity studies across the Caribbean Sea and the Atlantic Ocean.

First Time

The benthic dinoflagellate genus Cabra is reported for the first time in the Mediterranean Sea and the South Atlantic Ocean, with additional records in the Caribbean Sea and the eastern Asian coasts. Cabra aremorica is reported for the first time after the original description. However, these records should be considered cautiously because the distinction between Cabra aremorica and C. reticulata is difficult based on routine light microscopy observations. It is uncertain whether there is a high intraspecific morphological variability or several co-occurring undescribed species. Cabra levis, a species recently described, is reported for first time beyond the type locality. Nuevos registros del distintivo género de dinoflagelado bentónico Cabra (Dinophyceae) El dinoflagelado bentónico del géneroCabrase describe por primera vez en el Mar Mediterráneo y el Océano Atlántico Sur, con registros adicionales en el Mar Caribe y las costas orientales de Asia. Cabra aremorica se cita por primera vez después de la descripción original. Sin embargo, estos registros deben ser considerados con cautela porque la distinción entre Cabra aremorica y C. reticulata es difícil basándose solo en observaciones rutinarias de microscopía óptica. No está claro si existe una alta variabilidad morfológica intra-específica o si existen varias especies no descritas que coexisten. Cabra levis, una especie recientemente descrita, se describe por primera vez más allá de su localidad tipo.

Video Surveys

Fifteen morphotypes of deep-sea holothurians were documented by photography or videography at depths of 596–2,566 m, using Remote Operated Vehicles (ROV) video surveys and towed camera transects, during hydrocarbon exploratory activities in the Colombian Southern Caribbean. Most of the morphotypes were identified to the species level based on the images. The species belong to four orders, Apodida (1 species), Persiculida (3 species), Elasipodida (8 species), and Synallactida (3 species). Four species, three genera, and three families are reported for the first time in the Colombian Caribbean Sea. Some of the reports also represent first records for the Caribbean Sea and the Atlantic Ocean.

Abstract Migrating birds contend with dynamic wind conditions that ultimately influence most aspects of their migration, from broad-scale movements to individual decisions about where to rest and refuel. We used weather surveillance radar data to measure spring stopover distributions of northward migrating birds along the northern Gulf of Mexico coast and found a strong influence of winds over nonadjacent water bodies, the Caribbean Sea and Atlantic Ocean, along with the contiguous Gulf of Mexico. Specifically, we quantified the relative influence of meridional (north–south) and zonal (west–east) wind components over the 3 water bodies on weekly spring stopover densities along western, central, and eastern regions of the northern Gulf of Mexico coast. Winds over the Caribbean Sea and Atlantic Ocean were just as, or more, influential than winds over the Gulf of Mexico, with the highest stopover densities in the central and eastern regions of the coast following the fastest winds from the east over the Caribbean Sea. In contrast, stopover density along the western region of the coast was most influenced by winds over the Gulf of Mexico, with the highest densities following winds from the south. Our results elucidate the important role of wind conditions over multiple water bodies on region-wide stopover distributions and complement tracking data showing Nearctic–Neotropical birds flying nonstop from South America to the northern Gulf of Mexico coast. Smaller-bodied birds may be particularly sensitive to prevailing wind conditions during nonstop flights over water, with probable orientation and energetic consequences that shape subsequent terrestrial stopover distributions. In the future, the changing climate is likely to alter wind conditions associated with migration, so birds that employ nonstop over-water flight strategies may face growing challenges.
