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.

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.

Three New Species

Three new species of Cumacea are described from Costa Rican coastal waters. The bodotriids, Cyclaspys breedyae n. sp. and Cyclaspis vargasae n. sp., occurred on the Pacific coast, and the nannastacid, Cumella spinifera n. sp., came from a shallow back reef habitat of the Caribbean coast. Cyclaspis breedyae n. sp., which was collected from shallow water (1 1.5 m) at a beach just north of Puerto Caldera, has affinities with Cyclaspis varians Calman, 1912 from the northwestern Atlantic; it differs by having a carapace with fewer (usually 4), but larger, dorsal spines behind the ocular lobe and by having the pseudorostrum not extending beyond the ocular lobe. Cyclaspis vargasae n. sp., which was collected at a depth of 35 m off San Jos Island on the northwest coast, has some similarities with western Atlantic species, Cyclaspis alba Roccatagliata & Moreira 1986 and C. variabilis Roccatagliata & Moreira, 1986, but it differs from these species by having a carapace with oblique dorsal crests and a lateral ridge running anteriorly from the posteroventral margin of the carapace to just above the antennal notch. Cumella spinifera n. sp. was collected on the Caribbean coast at Puerto Vargas and has its closest affinities with C. zimmeri Petrescu, Iliffe, & Sarbu, 1994, known from shallow Caribbean waters off Jamaica. It is distinguished from the Jamaican species by several characters, including having the female carapace with more dorsal spines (10 verses 3 on the carapace of C. zimmeri) and being more dorsally pronounced with a papulate integument.

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.

Geographically widespread material originally assigned to the Floridan species Bryopesanser pesanseris (Smitt, 1873)was thoroughly examined and found to mask a hitherto unknown diversity. Smitt’s (1873) species has previously beennoted as “well-known and widely distributed” but this is not the case. This paper reviews the species previously assignedto Bryopesanser Tilbrook, 2006 (B. pesanseris, B. capitaneus, B. grandicella, and B. latesco) and describes 11 new species(B. tonsillorum n. sp., B. gardineri n. sp., B. puncturella n. sp., B. thricyng n. sp., B. ascendosolaris n. sp., B. ecphyma-totes n. sp., B. hebelomaia n. sp., B. lobiones n. sp., B. crebricollis n. sp., B. baderae n. sp., B. tiara n. sp.). All the Bry-opesanser species are, to a greater or lesser extent, geographically limited in their distribution. However, two species aremore widespread than the rest and truly Indo-Pacific in their distribution: B. latesco is recorded from the Red Sea, acrossthe Indo-Pacific to the Caribbean coast of Panama; B. tonsillorum n.sp. is even more broadly distributed, from Sri Lanka and Indonesia to the Pacific coast of Colombia and also West Africa.

A New Species

The family Chrysopetalidae has been poorly studied from the Pacific coast of Mexico compared to other families. Specifically from the southern Mexican Pacific, only two species of the family have been recorded in previous studies, Chrysopetalum occidentale and Paleanotus chrysolepis. In this study 311 specimens were revised, and nine species, belonging to six genera were found. Eight of these species are new records from the southern Mexican Pacific coast: Arichlidon watsonae n. sp., Bhawania cf. goodei, Chrysopetalum elegantoides, C. maculata, Hyalopale sp., Paleaequor psamathe, Paleanotus bellis and P. purpurea. A new species is also described, Arichlidon watsonae n. sp., which is characterized by the curved tips blades of the falcigers and their small and ovoid palps. Additionally, the genera Arichlidon and Hyalopale are recorded by first time from the Tropical Eastern Pacific.

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.

Four new shallow water species of the genus Pacifigorgia were found in recent surveys along the Pacific coast of Panama. One of the species was only found in dense patches at two shallow seamount-like localities inside the Coiba National Park, Gulf of Chiriqu . Two other species were patchily distributed at several localities in the Gulf of Chiriqu . A fourth species was widely distributed around the gulfs of Chiriqu and Panama encompassing a broad range of habitats and depths. The new species are described and illustrated in detail with scanning electron micrographs (SEM) of the sclerites, and colour photographs of the colony forms. The suspected occurrence of a particular Pacifigorgia species for this region is confirmed and two other new records are added to the species list. With the new four species, a total of 15 are established for Panama, making 31 species for the eastern Pacific to date.

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]

Two new species of Brazilian Psychoda Latreille are described, and Psychoda alternata Say and P. zetoscota Quate are recorded for the first time from Brazil. Psychoda divaricata Duckhouse, already described from southern Brazil, was recorded in the northeastern part of that country, as well as in the eastern Amazon region. The supraspecific classification proposed for the species of Psychoda according to Quate (= Psychodini of Jeñek) are discussed. A new classification is suggested that considers only one genus, Psychoda, divided into 12 subgenera: subgenus Psychoda Latreille, subgenus Copropsychoda Vaillant, subgenus Falsologima Jeñek & Harten, subgenus Psychodula Jeñek, subgenus Psychomora Jeñek, subgenus Psychana Jeñek & Harten, subgenus Logima Eaton, subgenus Tinearia Schellenberg, subgenus Chodopsycha Jeñek, subgenus Ypsydocha Jeñek, subgenus Psychodocha Jeñek, and subgenus Psycha Jeñek. A list of the Psychoda species from Latin America and the Caribbean region is presented.

An overview of the Polycystididae from the Indian Ocean is presented, including the description of twelve new species. The taxonomical position of each of these species is discussed. Austrorhynchus kerguelensis n. sp., Paraustrorhynchus neleae n. sp., Paulodora ancora n. sp., P. contortoides n. sp., P. drepanophora n. sp., P. hamifer n. sp., P. porcellus n. sp., P. schockaerti n. sp., P. watsoni n. sp., Phonorhynchoides linguatus n. sp. and Polycystis elsae n. sp. can all be distinguished from their congeners on characteristics of the construction of the hard parts of the male system. The older records of Paulodora contorta (Schockaert & Karling, 1975) Artois & Schockaert, 1998 by Schockaert (1982) and Jouk & De Vocht (1989) are re-evaluated and the material is recognised as Paulodora drepanophora n. sp.. The subspecies P. felis asymmetrica Artois & Schockaert, 2001 is raised to the species level. Annalisella bermudensis Karling, 1978, Paraustrorhynchus elixus (Marcus, 1954) Karling & Schockaert, 1977 and Phonorhynchoides haegheni Artois & Schockaert, 2001 are recorded for the first time in the Indian Ocean. The new material of these species is discussed and compared with older descriptions. For Alcha evelinae Marcus, 1949, Cincturorhynchus karlingi Schockaert, 1982, Djeziraia pardii Schockaert, 1971 Gyratrix hermaphroditus Ehrenberg, 1831, Paulodora subcontorta (Schockaert, 1982) Artois & Schockaert, 1998 and Polycystis ali Schockaert, 1982 new localities are given, and newly collected material is discussed. The discussion of P. ali leads to the split of the species into P. ali Schockaert, 1982 from the African East Coast and Galapagos and P. californica n. sp. from California. For some of the species, new records outside the Indian Ocean are also mentioned.
