A list of identified oribatid ptyctimous mites from Lesser Antilles and Bahamas, including 18 species, six genera and three families, is provided. Of these, three species are new records for the Caribbean, and three species are new to science. Oribotritia grossa Niedbała sp. nov. differs from other neotropical Oribotritia by the presence of relatively short, thick, distally blunt sensilli. Arphthiracarus alienus Niedbała sp. nov. differs from other Arphthiracarus species by the presence of uniquely shaped sensilli, short spiniform setae, the median sigillar field long and narrow with an incision between the rostral setae, four pairs of notogastral lyrifissures and the location of vestigial setae f1 anterior to h1. Arphthiracarus strictus Niedbała sp. nov. differs from A. brasiliensis Niedbała, 1988, A. iubatus Niedbała, 2003, A. latebrosus (Niedbała, 1982) and A. pervalidus Niedbała, 2003 by the presence of a unique tight location of genital setae g4-6 and bifurcated setae d of femora I. In addition, descriptions of three tritonymphs are presented.

This report supplements an earlier account on the hydroids of the Guadeloupe archipelago, and records 31 additional species of thecates. Among them, Halecium calderi sp. nov., Antennella armata sp. nov., and Antennella incerta sp. nov., are described. Laomedea tottoni Leloup, 1935 is redescribed and reassigned to the genus Clytia Lamouroux, 1812. Its synonymy is broadened upon inclusion of Clytia laxa Fraser, 1937. Hebella venusta (Allman, 1877) is considered valid based on comparison with related species, and its gonotheca is described for the first time. Two sympatric varieties of Sertularella diaphana (Allman, 1885), easily separable morphologically and by their cnidome composition, are discussed. Sertularella ornata Fraser, 1937 is recorded for the second time and is fully redescribed. Its name is actually a junior synonym of S. fusiformis (Hincks, 1861) f. ornata Broch, 1933, and it is here referred to as S. fraseri nom. nov. Sertularia thecocarpa Jarvis, 1922, Sertularella minuscula Billard, 1924, Sertularella parvula Mammen, 1965, and Sertularia stechowi Hirohito, 1995 are placed in the synonymy of Sertularella tongensis Stechow, 1919, the latter being transferred to the genus Sertularia Linnaeus, 1758. Sertularia ephemera nom. nov. is proposed as a replacement name for Sertularia tongensis Stechow, 1919. Aglaophenia postdentata Billard, 1913 is confidently recorded from the Atlantic for the first time. Dentitheca dendritica (Nutting, 1900) is redescribed, and additional notes on Macrorhynchia clarkei (Nutting, 1900) are provided. All the species discussed herein are new records for the study area. Illustrations are given for each species and data on the nematocyst complement and size of capsules are given when necessary. The number of hydroid species reported from the study area is raised to more than eighty. Hydroids of the Caribbean are moderately well known faunistically, though continuous discovery of new species is likely, the species composition being certainly richer than currently reported.

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.

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.

Sæther (1981) erected the genus Diplosmittia based on a species from Saint Lucia and Saint Vincent in the British West Indies. The genus was revised by Pinho et al. (2009). To date, the genus comprises ten species: Diplosmittia harrisoni Sæther, 1981; D. carinata Sæther, 1985; D. recisus Sæther, 1988; D. beluina Andersen, 1996; D. forficata Andersen, 1996; D. plaumanni Pinho, Mendes & Andersen, 2009; D. boraceia Pinho, Mendes & Andersen, 2009; D. aragua Pinho, Mendes & Andersen, 2009; D. cerayma Pinho, Mendes & Andersen, 2009; and D. caribensis Wiedenbrug & Silva, 2016. Diplosmittia sasai Makarchenko & Makarchenko, 2005 was placed as a synonym of Pseudosmittia mathildae Albu, 1968 by Makarchenko & Makarchenko (2008). Except for D. carinata from Michigan, U.S.A., all species are Neotropical and mostly recorded from the Caribbean and northern part of South America. During field work in a remote mountainous region in the Brazilian Amazon, a unique new species with the gonostylus split into three parts was collected and is described and figured below. In addition, new records of D. plaumanni are provided.

The reef system off the Amazon River mouth extends from Amapá state to Maranhão state along the Brazilian Equatorial Margin, encompassing more than 10,000 km2 of rhodolith beds and high-relief hard structures on the outer shelf and upper slope. This unique hard bottom mosaic is remarkable for being influenced by the turbid and hyposaline plume from the world’s largest river, and also for representing a connectivity corridor between the Caribbean and Brazil. Bryozoans were recently recognized as major reef builders in the Southwestern Atlantic, but their diversity off the Amazon River mouth remained unknown. Here, we report on recent collections obtained from 23 to 120 m depth in Northern Brazil. Sixty-five bryozoan taxa were characterized using scanning electron microscopy, including 57, five and three taxa of Cheilostomatida, Cyclostomatida and Ctenostomatida, respectively. Cribrilaria smitti and three genera (Cranosina, Glabrilaria and Thornelya) are new records for Brazil, and 13 new species are herein described: Antropora cruzeiro n. sp., Cranosina gilbertoi n. sp., Cribrilaria lateralis n. sp., Crisia brasiliensis n. sp., Glabrilaria antoniettae n. sp., Micropora amapaensis n. sp., Parasmittina amazonensis n. sp., Plesiocleidochasma arcuatum n. sp., Poricella bifurcata n. sp., Pourtalesella duoavicularia n. sp., Stephanollona domuspusilla n. sp., Therenia dianae n. sp., and Thornelya atlanticoensis n. sp. Our results highlight the biodiversity significance of the Amazon reefs and the need for more comprehensive sampling to clarify the role of bryozoans in modern turbid-zone reefs and rhodolith beds.

The sponge class Homoscleromorpha has a challenging taxonomy and its systematics is still a matter of debate. A significant effort has recently been deployed to better evaluate the diversity of these sponges, and each new exploration of cryptic habitats reveals new species. Although several undescribed or wrongly determined Oscarella-like sponges have been reported by different authors, the Oscarellidae family still lacks description of its true Caribbean representatives. The exploration of various submarine caves in the Lesser Antilles has allowed us to find and to formally describe the first two Oscarellidae of the Caribbean Sea, Oscarella filipoi sp. nov. and Oscarella zoranja sp. nov. Both new species are quite common in semi-dark habitats throughout the Lesser Antilles. Moreover, O. filipoi sp. nov. is the largest Oscarellidae ever observed world-wide. Both species harbor a sylleibid aquiferous system and a high density of ovoid to spherical choanocyte chambers. The molecular taxonomy clearly shows their affiliation to the Oscarella clade containing the type species of the Oscarellidae family. In addition to their growth forms, these two species differ in the shape of their mesohylar cells, and in the degree of development of their basal region. This latter trait is particularly remarkable in large specimens of O. filipoi which can have a very thick ectosome.

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.

The known cicada fauna of the Republic of Trinidad and Tobago is identified. Calyria hyperochelabrys n. sp., Carineta trinidadensis n. sp., and Herrera grammosticta n. sp. are described as new. The first records of Fidicinoides descampsi Boulard & Martinelli, 1996, Proarna hilaris (Germar, 1834), Guyalna bogotana (Distant, 1892a), Majeorona aper (Walker, 1850), Taphura boulardi Sanborn, 2011a, Carineta matura Distant, 1892b, and Herrera nigropercula Sanborn, 2020b are provided. The first reports for the genera Guyalna Boulard & Martinelli, 1996, Majeorona Distant, 1905d, Calyria Stål, 1862, Carineta Amyot & Audinet-Serville, 1843 and Herrera Distant, 1905c and the tribes Parnisini Distant, 1905e and Carinetini Distant, 1905c are represented by the records for the new species and new records. The first records of Proarna hilaris (Germar, 1830) for Anegada, Antigua, Grenada, Canoun Island, Mayreau Island and Union Island in the Grenadines, Little St. James, Little Thatch Island, Montserrat, Mosquito Island, and St. Kitts, Proarna palisoti (Metcalf, 1963a) for Navarro Island, Majeorona aper (Walker, 1850) for Grenada, and Ariasa albimaculosa Sanborn, 2016c for Bonaire are provided to increase the known distributions of these species and the Caribbean fauna. The currently known cicada fauna for Trinidad is increased here to 15 species representing ten genera, four tribes and two subfamilies. Only Quesada gigas (Olivier, 1790) is known currently from Tobago.
