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.

Alpheid Shrimp

The present study deals with two species new to science, as well as several new records in the closely related alpheid shrimp genera Salmoneus Holthuis, 1955 and Deioneus Dworschak, Anker & Abed-Navandi, 2000, based on material collected at various localities in the tropical western and eastern Atlantic Ocean. In the western Atlantic, Salmoneus inconspicuus sp. nov. is described based on material from the Caribbean coast of Panama, Cuba, French Antilles and (with some doubts) Bermuda. The new species has been previously reported from the eastern Caribbean Sea as S. teres Manning & Chace, 1990, a closely related species so far known only from Ascension Island in the central Atlantic. Salmoneus camaroncito Anker, 2010 is reported from the Caribbean coast of Mexico, for the first time since its original description. Salmoneus carvachoi Anker, 2007 is reported from Colombia and southeastern USA, representing a new record of the species for each of these countries. Salmoneus depressus Anker, 2011 and Salmoneus setosus Manning & Chace, 1990 are reported for the first time from Cuba and Panama, respectively. In addition, these two species, as well as Salmoneus wehrtmanni Anker, 2010, are reported from new localities in Mexico. In the eastern Atlantic, Salmoneus saotomensis sp. nov. is described based on a single specimen from São Tomé Island in the Gulf of Guinea. The new species is characterised by the somewhat enlarged minor cheliped and is compared to all other Atlantic species presenting this feature. Deioneus sandizelli Dworschak, Anker & Abed-Navandi, 2000 is reported from São Tomé Island, for the first second time since its original description based on the Cape Verde type material. The characters separating Deioneus and Salmoneus are reassessed. The new evidence shows that these two genera are distinguished by only one morphological feature known to be variable in at least one non-related alpheid genus. However, in view of the increasing morphological heterogeneity in Salmoneus, it seems more appropriate to retain Deioneus as a valid genus for it may represent a distinct clade that also includes several other species currently placed in Salmoneus.

A New Species

The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.

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.

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.

Amphipod material collected from Brazil on Ilha do Arvoredo, (Santa Catarina), Campos Basin, (Rio de Janeiro) and Espírito Santo Basin (Espírito Santo) in the southwestern Atlantic Ocean yielded new taxonomic findings for the subfamily Phtisicinae Vassilenko, 1968. Hemiproto wigleyi McCain, 1968, previously recorded from the Gulf of Mexico to the Caribbean Sea, is herein redescribed and recorded for the first time from the Brazilian coast. The type material of Phtisica verae Quitete, 1979, a poorly described species recorded from Brazil and based only on its original description, was examined and considered herein as a junior synonym of P. marina Slabber, 1769, a well-known and widely distributed species from the Atlantic Ocean and the Mediterranean Sea. In this paper, Phtisica marina is redescribed, with its two morphotypes of male gnathopod two, and compared with previous descriptions. The geographic distribution of both H. wigleyi and P. marina is provided.

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.

This paper describes rare Cardiomya species from Brazil which have been hitherto misidentified as Cardiomya cleryana (d’Orbigny, 1842) in literature or museum collections. Cardiomya minerva sp. nov. is proposed as new species and is characterized by its quadrangular shell, short and truncated rostrum, and external ornamentation composed of six radial ribs on the posterior half of the shell flank. Cardiomya striolata (Locard, 1897) described from the Mediterranean Sea and northwestern Atlantic Ocean, is reported from Brazil for the first time; although previously regarded as a junior synonym of Cardiomya costellata (Deshayes, 1835), it is herein considered as a full species and redescribed. This species is characterized by its trapezoidal shell flank, elongated rostrum, tapering towards the tip, and external ornamentation composed of 18–53 radial ribs, the 3–4 posterior ones being the strongest and more widely spaced. Other three previously unknown species are illustrated but not formally named due to the lack of well-preserved articulated shells.

Eleven Species

Calcareous sponges of the subclass Calcinea from Martinique (Caribbean Sea) are presented under an integrative perspective (morphology and DNA: ITS and C-LSU). Eleven species of six genera have been found in Martinique, three of them being new to science: Borojevia crystallina sp. nov., Clathrina delicata sp. nov., and Ernstia adunca sp. nov. Among these new records, four species were previously known from other Caribbean localities: Arturia vansoesti, Clathrina insularis, C. mutabilis, and Leucaltis clathria. Two species previously known in Brazilian waters are reported for the first time in the Caribbean Sea: Arturia alcatraziensis and C. cf. cylindractina. Finally, the occurrence of C. aurea and Leucetta floridana in Martinique is confirmed. The two molecular markers (ITS and C-LSU) and the morphological characters considered (e.g. body shape, aquiferous system and spicules) provided congruent classifications what tend to confirm their reliability for the taxonomy of Clathrinida. After the present work, a total of 17 species of Calcarea are recognised for Martinique. We discuss three types of distribution patterns (Endemic, Caribbean-Brazil, and Amphi-Atlantic), Martinique likely playing an important role as stepping stone to garantee connectivity among populations of Calcinea in the Atlantic.

Five species of shrimps, four carideans and one stenopodidean, are recorded for the first time from the Caribbean coast of Panama: Lysmata vittata (Stimpson, 1860) [Lysmatidae Dana, 1852], Periclimenaeus ascidiarum Holthuis, 1951, P. bredini Chace, 1972, P. maxillulidens (Schmitt, 1936) [Palaemonidae Rafinesque, 1815], and Odontozona edyli Criales & Lemaitre, 2017 [Stenopodidae Claus, 1872]. Rather surprisingly, L. vittata is recorded from the Caribbean Sea for the first time. However, the taxonomic status of all western Atlantic specimens currently assigned to L. vittata (including the Panamanian material and the Brazilian L. rauli Laubenheimer & Rhyne, 2010) will need a much more careful reassessment, which will only be possible after determining the taxonomic identity of L. vittata in the Indo-West Pacific. The colour patterns of P. ascidiarum, P. bredini and O. edyli, herein illustrated for the first time, appear to be species-diagnostic and may serve as additional important taxonomic characters. For O. edyli, the previously unknown thoracic sternum of the female is illustrated, as well as the variation in the rostral dentition.
