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.

Two new species of Selenops, S. anacaona sp. nov. (♀) and S. caonabo sp. nov. (♀), are described from the Dominican Republic on the Caribbean island of Hispaniola. These two new species increase the number of endemic Selenops on Hispaniola to 13, surpassing Cuba, which currently has 11 endemic species. Additionally, the male of S. pensilis Muma, 1953 from Hispaniola is described, as well as the male of S. petrunkevitchi Alayón, 2003 from Jamaica. Full distribution records are given for the new species and the newly described males, and new records are provided for the following species: S. aequalis Franganillo, 1935, S. bocacandensis Crews, 2011, S. candidus Muma, 1953, S. micropalpus Muma, 1953, S. morro Crews, 2011, S. simius Muma, 1953, S. souliga Crews, 2011, and S. submaculosus Bryant, 1940.

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.

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.

Three new species are described and illustrated: Berosus illuviosus sp. n., B. parvus sp. n., and B. andreazzei sp. n. In addition, we present a checklist of the Berosus species collected in 26 ponds in the savanna area of the State of Roraima, with 12 new species records for the state, five of which are also new country records for Brazil.

In the revision of the Ceratopogonini of the World, Wirth & Grogan (1988) placed the species of the Monohelea multilineata group in the new genus Downeshelea, which includes 33 species (Borkent, 2011), most of them known from the New World. Borkent and Spinelli (2000, 2007) listed 18 species from the Neotropical Region and Felippe-Bauer and Silva (2008) subsequently described D. oliveirai Felippe-Bauer from northern Brazil. From Mexico, only D. multilineata (Lutz) and D. panamensis (Lane & Wirth) have been reported.

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.

Of the 69 Neotropical species of Stylogaster, only one record was previously known from Northeastern Brazil (from Bahia state in 1985—S. brasilia Camras & Parrillo). Several specimens from this region housed at the MNRJ collection were studied, mostly from Bahia, Ceará and Pernambuco states. Two new records were obtained: S. macrura Lopes, 1938, previously known from São Paulo state (Southeastern Brazil), and S. souzai Monteiro, 1960, from Amapá and Pará (Northern Brazil). Descriptions of two new species, S. hugoi sp. nov. and  S. planitarsis sp. nov. are presented, as well as that of the previously unknown female of S. souzai. Illustrations and geographic distribution of the species are also provided.

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.
