A new snapping shrimp is described based on several specimens collected on a shallow coral reef off Isla Popa in Bocas del Toro, on the Caribbean coast of Panama. All specimens of Alpheus naranjo sp. nov. were extracted from dead colonies of the thin-leaf lettuce coral, Agaricia tenuifolia Dana, at a depth of about 2 m. Based on its morphological characteristics, the new species belongs to a small species complex that also includes A. blachei Crosnier & Forest, 1965 from the tropical eastern Atlantic, and A. felgenhaueri Kim & Abele, 1988 and A. confusus Carvacho, 1989, both from the tropical eastern Pacific. Alpheus naranjo sp. nov. can be separated from all of them by the relatively longer fingers of the minor chela, which are devoid of balaeniceps setae, as well as some other morphological details. In the western Atlantic, A. naranjo sp. nov. is the only large uniformly orange-red snapping shrimp, hence its proposed new name. The colour patterns of A. blachei and A. confusus are illustrated for the first time.

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.

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]

This paper deals with the moDusk species known from the Ciénaga Grande de Santa Marta and from the littoral zone and the upper continental shelf of the coastal strip between lala de Salamanca and the balneario El Rodadero (Caribbean coast of Colombia, South America). 468 species and subspecies ofmarine, brackish-water and freshwater mollusks are reponed comprising 211 bivalves. 6 scaphopods and 251 gastropods. 101 species and 1 subspecies have been found in the Ciénaga Grande (most of them also in the sea), a further 9 marine species have been recorded only as old shells in the estuarine part of the Ciénaga Grande, the rest have been collected exclusively in the marine part of the investigated area. 268 species (120 bivalves, 3 scaphopods and 145 gastropods) have been live-collected, the remainder only as empty shells. 165 species and 9 subspecies (90 + 1 bivalves and 75 + 2 gastropods) are monographed and discussed in detail, among them 98 species and 1 subspecies (48 bivalves and 50 + 1 gastropods) from the Ciénaga Grande or its estuarine región, and 67 species and 2 subspecies only from the sea. Of the 98 species from the Ciénaga Grande, 64 have been live-collected, tlte oth*er 34 as empty shells only. The Ciénaga Grande de Santa Marta is the largest coastal lagoon of the Caribbean coast of Colombia, occupying an area of 450 km'. According to the season, drastic changes in salinity of between 0 and S0*/oo may be observed. Depth varies between 1 and 2.5 m, and the shore mostly consists of mangrove swamps. The bottom is muddy, some more or less extended areas having oyster reefs or shell concentrates. There are small areas in the northern part with sandy bottoms. Most mollusk species enter the lagoon and spread out within it as planktonic larvae by means of the currents, if conditions are favourable. Only very rarely are adult snails able to enter {he Ciénaga Grande actively. The propagation of the planktonic larvae within the lagoon depends on the nearest natural occurrence of the species, the duration of the pelagic phase, settlement depends on the presence of suitable substrate (besides the other ecological conditions needed). On account of finding older empty shells in a relative uniform state of preservation throughout the whole basin of the Ciénaga Grande, and of species not having been encountered there live, it can be assumed that there had previously existed an extremely long period of high salinity in the lagoon, with lower amplitudes than nowadays. According to C dates this period can be located ¿00-360 years ago, and its duration is estimated at at lea»t 3.5 years. The reason for this was most probably the greater interchange of sea and lagoonal water through several no longer existing, but still traceable, inlets. The zoogeographic division of those species treated in detail (except the freshwater species) is as follows: western Atlantic species. 68; Caribbean species. 48: southern Caibbean species, partly also from Brasil, 39. Í2 species are amphi-atlantic and 5 amphi-american. Six species known from Suriname, Venezuela or Brasil are recorded for the first time from Colombia and the southwestern Caribbean. 69 species have a win species (cognate species) existing in the Eastern Pacific (Panamic zoogeographic province). The portion of species with Pacific twin species found in the studied area is very high in comparison with other regions of the Caribbean, especially among the bivalves. This is due most probably to the similarity of the biotopes on large parts of the Colombian Caribbean coast and the tropical Eastern Pacific coast, preferred by these species.

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.

Several species of the infaunal alpheid genera Leptalpheus Williams, 1965 and Fenneralpheus Felder & Manning, 1986 are described as new or reported from new localities in the tropical western Atlantic and eastern Pacific. In the genus Leptalpheus, five species are described as new: L. marginalis sp. nov. from the Caribbean coast of Colombia; L. penicillatus sp. nov. from the Pacific coast of Panama and Costa Rica; L. azuero sp. nov., L. hendrickxi sp. nov., and L. bicristatus sp. nov., all three from the Pacific coast of Panama. In addition, L. cf. forceps Williams, 1965 and L. felderi Anker, Vera Caripe & Lira, 2006 are reported for the first time from the Caribbean coast of Panama. Several unidentified species of Leptalpheus presently known from incomplete or immature specimens are also reported. In the genus Fenneralpheus, F. orabovis sp. nov. is described as new, whereas F. chacei Felder & Manning, 1986 is reported from the Caribbean coast of Panama, representing the first finding of this species outside its type locality in Florida. The generic diagnoses of both Leptalpheus and Fenneralpheus are emended to accommodate the new species.

The present study is a preliminary report on 36 Atlantic species of the snapping shrimp genus Synalpheus Spence Bate, 1888; 32 from the western Atlantic and four from the eastern Atlantic. The vast majority of specimens were collected along the Caribbean coast of Panama between 2005 and 2008 and around São Tomé Island in 2006. Additional specimens were collected in Costa Rica, Honduras, Belize, Mexico, Dominican Republic, Aruba, Venezuela, Florida, Brazil and Cape Verde, between 1998 and 2011. Some older museum material was also examined. Three nominal varieties or subspecies, viz. S. tumidomanus africanus Crosnier & Forest, 1965, S. tumidomanus congoensis Crosnier & Forest, 1965 and S. minus var. antillensis Coutière, 1909 are elevated to full species rank, becoming S. africanus, S. congoensis, and S. antillensis, respectively. Several species are reported for the first time from Panama, Honduras, Dominican Republic, Aruba, St. Martin, and Brazil. General taxonomic and/or ecological notes are provided for all species treated herein. The need for more taxonomic and molecular work is highlighted for the western Atlantic S. cf. africanus, S. anasimus Chace, 1972, S. apioceros Coutière, 1909, S. bousfieldi Chace, 1972, S. brooksi Coutière, 1909, S. fritzmuelleri Coutière, 1909, S. goodei Coutière, 1909, S. herricki Coutière, 1909, S. cf. longicarpus (Herrick, 1891), S. ul (Ríos & Duffy, 2007) and S. yano (Ríos & Duffy, 2007), as well as the eastern Atlantic S. cf. africanus. Most species reported are illustrated in colour, some for the first time. New sponge hosts are recorded for several species of the S. gambarelloides (Nardo, 1847) group. A table summarising life habits and social organisation for all presently known Atlantic species of Synalpheus is provided. Keys for the identification of all presently known western and eastern species of Synalpheus are also provided.

We report the occurrence of the sponge-dwelling snapping shrimpSynalpheus dardeaui(Decapoda: Alpheidae) for the first time from Porto Seguro (Bahia, Brazil) and record an additional sponge host for the species,Irciniacf.strobilina. Synalpheus dardeauiwas previously known from Florida and some localities in the Caribbean Sea. Therefore, the present finding represents the first record of the species in the south-western Atlantic, extending its southern distribution limit by a latitude of 28° from Curaçao (12°N) to Porto Seguro (16°S). Variations between the Brazilian and Florida–Caribbean materials are discussed and illustrated.

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.

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.

Final Closure

Molluscs are the most diverse and abundant tropical American macrofossils, but their distributions and evolution are not well understood. Classic studies by Olsson and Woodring documented a rich Late Miocene to Early Pliocene “Gatunian” fauna throughout the Caribbean and tropical Eastern Pacific, with many species in common between the oceans. This fauna was divided by formation of the Isthmus of Panama, and diverged into distinct Pacific and Caribbean faunas sometime thereafter. Diversity also decreased by about half in the Caribbean. However, the timing, rates and correlation of these major biological changes with changes in environmental conditions have not been resolved because of imprecise dating and taxonomy and failure to consider problems of sampling and biofacies in biological comparisons. We used the newly revised late Neogene stratigraphy for Panama and Costa Rica to date for the first time the radiation and extinction of molluscs on opposite sides of the Isthmus. Data include occurrences throughout tropical America for nearly 100 species of the Strombina-group (Gastropoda, Columbellidae) and for more than 500 gastropod and bivalve genera from 240 Late Miocene to Pleistocene isthmian collections.All evidence suggests that final closure of the Isthmus of Panama occurred between 3.5 and 2.5 My. Subgeneric divergence between the oceans was well developed, and trans-isthmian species were rare by the Early Pliocene, at least 2 Ma before final closure. Caribbean diversity remained high until 1.8 to 1.5 Ma when massive but selective extinction occurred. This was at least 1 Ma after final closure of the Isthmus, and may be correlated with onset of slightly cooler Caribbean sea surface temperatures in the Pleistocene. In contrast, Eastern Pacific diversity did not decline, and even increased during the Pleistocene.
