PRIMER HALLAZGO DE APIOMITHRAX VIOLACEUS (A. MILNE-EDWARDS) (BRACHYURA: EPIALTIDAE: PISINAE) PARA EL CARIBE

Up to now, the sub-family Pisinae Dana, 1851 was represented in the Caribbean coasts of Venezuela by six species [Chorinus heros (Herbst, 1790); Libinia ferreirae Brito Capello, 1871; Herbstia depressa Stimpson, 1870; Sphenocarcinus corrosus A. Milne-Edwards, 1878; Pelia mutica (Gibbes, 1850) and Nibilia antilocapra (Stimpson, 1871)], which make up 38 % of the Pisinae crabs reported for the Caribbean Sea. During an examination of unidentified material from the crustacean collection of the Laboratory of Carcinology at Universidad de Oriente, Margarita Island, Venezuela, nine specimens (six males and three females) of Apiomithrax violaceus (A. Milne-Edwards, 1868) were discovered. Until now the distribution of this Pisinae species was known to range from Mauritania to Angola in the eastern Atlantic, Ascension Island in the central Atlantic, as well as Brazil and Orinoco Delta in the western Atlantic. All specimens were collected in Venezuelan waters, at the following locations: Margarita island: Playa Valdés, Península de Macanao, Boca Chica, El Maguey; Sucre State (mainland): Guayacán. This is the most northerly record of the species and it is the first time to be reported for the Caribbean Sea, increasing the number of known species of Pisinae to 17 in this area.

Alpheid Shrimp

Six species of the alpheid shrimp genus Salmoneus Holthuis, 1955, including two new species, are reported from the tropical western Atlantic. Salmoneus ortmanni (Rankin, 1898) is reported for the first time from Atol das Rocas, Brazil and Aruba, Netherlands Antilles. Salmoneus carvachoi n. sp. is described on the basis of specimens previously misidentified as S. ortmanni from Guadeloupe, French Antilles, and is also known to occur in Brazil. The main difference between S. carvachoi n. sp. and S. ortmanni is the much more slender dactylus of the third to fifth pereiopods in the first species. The two species also appear to be ecologically separated: S. carvachoi n. sp. prefers silt-mud bottoms of estuaries and mangroves, while S. ortmanni occurs mostly in the rocky-coralline algae intertidal and on seagrass beds with reef patches, under rocks and coral rubble. Salmoneus rocas n. sp. is described on the basis of a single specimen collected at Atol das Rocas; this species belongs to the mostly Indo-Pacific S. serratidigitus (Coutière, 1896) species complex. Salmoneus teres Manning & Chace, 1990 and S. setosus Manning & Chace, 1990 previously known only from the isolated Ascension Island in the central Atlantic, are reported for the first time from the tropical western Atlantic: Guadeloupe and northeastern Brazil, respectively. Finally, Parabetaeus hummelincki (Schmitt, 1936) is recorded for the first time in Brazil.

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.

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.

The Western Atlantic fire coral Millepora alcicornis is recorded from Madeira Island in the Eastern Atlantic for the first time. A large colony of this species has apparently been present at a very exposed site at the northern shore of Madeira Island for more than 15 years. Genetic analyses suggest that the colonies of this tropical fire coral at a mid-Atlantic location (Ascension Island) and at each of three Eastern Atlantic locations (Cape Verde Islands, Canary Islands, Madeira Island) originated from independent long-distance dispersal events from the Caribbean area.

Porites colonensis is a coral from the Caribbean Sea; colonies are foliaceous, undulated, and plate-like. Polyps are dark brown or red with small bright white or green centers; pali are present in corallites and the septal plan is bisymmetrical, conformed by three fused ventral septa, a dorsal solitary septum, and two pairs of lateral septa at each side of the dorso-ventral axis. P. colonensis is similar and can be confused with the smooth varieties of Porites astreoides and Porites branneri. There are three specimens collected from Colombia and previously identified as P. colonensis: one from Golfo de Urabá (Darién ecoregion), other from Islas del Rosario (Coralline Archipelagos ecoregion), and another from an unspecified locality, in addition to one published observation from the Golfo de Urabá without collected specimens. A recent finding of other specimens in the Tayrona National Natural Park (TNNP, Tayrona ecoregion) and the absence of a rigorous taxonomic revision for all specimens collected from Colombia showed that it was necessary to review the presence and distribution of P. colonensis in the Colombian Caribbean. A taxonomic review was done for all specimens collected from Colombia and previously identified as P. colonensis. Then, the morphologic variability of specimens that were confirmed as P. colonensis was described. Only the specimens from TNNP agreed with the holotype description of P. colonensis, while others agreed with flat varieties of P. astreoides. Thus, the presence of P. colonensis is confirmed for the first time for Colombia, but its presence in other Colombian localities outside Tayrona ecoregion could not be demonstrated. This is the only confirmed record of this species for the South American continental shelf. Furthermore, the skeletal characteristics of Colombian P. colonensis corallites showed large variability, exceeding the ranges previously described for the species.

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.

First Time

Spider crabs (Majoidea) are well-known from modern oceans and are also common in the western part of the Atlantic Ocean. When spider crabs appeared in the Western Atlantic in deep time, and when they became diverse, hinges on their fossil record. By reviewing their fossil record, we show that (1) spider crabs first appeared in the Western Atlantic in the Late Cretaceous, (2) they became common since the Miocene, and (3) most species and genera are found in the Caribbean region from the Miocene onwards. Furthermore, taxonomic work on some modern and fossil Mithracidae, a family that might have originated in the Western Atlantic, was conducted. Specifically,Maguimithraxgen. nov. is erected to accommodate the extant speciesDamithrax spinosissimus, whileDamithraxcf.pleuracanthusis recognized for the first time from the fossil record (late Pliocene–early Pleistocene, Florida, USA). Furthermore, two new species are described from the lower Miocene coral-associated limestones of Jamaica (Mithrax arawakumsp. nov. andNemausa windsoraesp. nov.). Spurred by a recent revision of the subfamily, two known species from the same deposits are refigured and transferred to new genera:Mithrax donovanitoNemausa, andMithrax unguistoDamithrax. The diverse assemblage of decapods from these coral-associated limestones underlines the importance of reefs for the abundance and diversity of decapods in deep time. Finally, we quantitatively show that these crabs possess allometric growth in that length/width ratios drop as specimens grow, a factor that is not always taken into account while describing and comparing among taxa.

One New Species

Sixty species of hydroids, assigned to 24 families and 39 genera, are recognized and discussed in a collection of material from the southwest coast of Florida. One new species (Clytia joycei) is described from turtlegrass (Thalassia testudinum) and reported as well from the Caribbean coast of Panama. Under provisions of the First Reviser Principle in the International Code of Zoological Nomenclature, Antennopsis nigra Nutting, 1900 is assigned precedence over its simultaneous synonym A. longicorna Nutting, 1900. Also included as a synonym of A. nigra is A. sinuosa Fraser, 1947b. The species is now assigned to Nemertesia Lamouroux, 1816, as N. nigra. Following Reversal of Precedence provisions in the code, the well-known name Halecium nanum Alder, 1859 is designated as valid and conserved as a nomen protectum, while Hydra articulata Bosc, 1797 is relegated to a nomen oblitum. The genus Monotheca Nutting, 1900 is upheld as valid on the basis of both morphological and molecular evidence. Sertularia pourtalesi Nutting, 1904, a seldom-reported species, is assigned to Dynamena Lamouroux, 1812 and recognized as distinct from D. disticha (Bosc, 1802). Calyptospadix cerulea Clarke, 1882 and Bimeria franciscana Torrey, 1902 (also known as Garveia franciscana) are taken to be conspecific, with Calyptospadix Clarke, 1882 treated as a valid genus. Confusion over the identity of Lovenella gracilis Clarke, 1882 in literature on North American hydroids is addressed, and topotypic specimens from the Chesapeake Bay region are illustrated to document characters that distinguish the species. Campanularia colombiana (Wedler, 1976) is reported for the first time outside the Caribbean coast of Colombia. The fauna studied here consists largely of species known to occur in the tropical and subtropical western Atlantic. [Zoobank URL: urn:lsid:zoobank.org:act:4C926BE2-D75D-449A-9EAD-14CADACFFADD]

The arrival of sargassum in a massive way generates adverse environmental, social and economic impacts. Little is known about its origin and trajectory, as well as the atmospheric and oceanic conditions under which it arrives at the Mexican coasts of the Caribbean. This poster presents a diagnosis of the seasonal, annual and interannual variability of atmospheric circulations in the Atlantic and Caribbean Sea, identifying the atmospheric conditions under which sargassum arrived on the Mexican coasts. 30 years of surface wind data from CFSR (Climate Forecast System Reanalysis) of NCAR on the Atlantic and Caribbean were analyzed, dividing the area into six areas, for each one its seasonal, annual and interannual variability was estimated, as well as its extreme values from 1989 to 2018, focusing the study on both the Caribbean Sea and the Atlantic coast of Brazil.Once the mean, extreme winds (10th and 90th percentiles) and their correlation with the NAO (North Atlantic Oscillation) were diagnosed interannually, particular years of the recent period were analyzed: from 2010 to 2019 incorporating the wind convergence as a physical process associated with the accumulation of sargassum, surface pressure and sea surface temperature (SST) and also correlating it with the NAO index.The results show that the atmospheric conditions for transporting sargassum along the Mexican coasts of the Caribbean are more favorable in summer than in winter, besides it, the higher extremes (90th percentile) in the Caribbean favor the transport of sargassum both in winter and in summer. However, "connectivity" with other regions (Central Atlantic) makes summer more favorable, but winter is potentially viable. The atmospheric conditions of recent extreme years are discussed: 2013 (without the arrival of sargassum), medium: 2015 and extreme 2018 (with abundant sargassum) for both summer and winter.
