In the framework of a research on taxonomy and ecology of selected families of polychaetes conducted at the field station of the Smithsonian Institution (Washington DC, USA) at Carrie Bow Cay (Belize, Western Caribbean Sea) on November 2005, several qualitative benthic samples from different habitats and substrate types (Thalassia testudinum shoots, fragments of dead hard corals, sponges) have been analyzed. In some of these samples, specimens of Sabellidae were found, revealing, together with some taxa already known for the area, the presence of two new species, Megalomma fauchaldi sp. nov., and Pseudoaugeneriella spongicola sp. nov., this latter representing a genus newly reported from the Caribbean. Sabellidae biodiversity and systematics between Caribbean and Mediterranean regions is also compared.

The new genus Svenzea is created to group three sponge species from tropical reef environments of the Caribbean Sea and Indonesia: Pseudaxinella (?) zeai Alvarez, Van Soest & Rützler, Svenzea cristinae n. sp. and S. devoogdae n. sp. The genus shows affinities with members of both Halichondrida and Haplosclerida but it is assigned to the family Dictyonellidae based on shared microanatomical and developmental features. The higher taxonomic position of Svenzea is a subject for future investigations.

Six species of hermit crabs of the family Paguridae from the Caribbean Sea and Gulf of Mexico region, including two new species, Anisopagurus asteriscus sp. nov. and Pagurus alarius sp. nov., are documented. The two new species are described, and recognition characters summarized for the four previously known species. Reports of the latter, Nematopaguroides fagei Forest & de Saint Laurent, 1968, N. karukera Lemaitre, Felder & Poupin, 2017, Paguriscus robustus Lemaitre, Felder & Poupin, 2017, and Pylopaguridium markhami McLaughlin & Lemaitre, 2001, represent range extensions for all four species. Color photographs are included for four of the species, as well as remarks on their taxonomy and distributions. All six species included can be categorized as micro-pagurids (with shield length rarely exceeding 2.0 mm), and were collected from cryptic reef habitats in Bocas del Toro, Panama; the French Antillean island of Guadeloupe; and the Gulf of Mexico coasts of Louisiana, Yucatán, and Florida Keys. The discovery of these new or rare species supports the conclusion of recent studies that the diversity of pagurids from the Caribbean region has yet to be fully realized.

A new genus is established in Eunicidae: Fauchaldius gen. nov., a symbiont of hexactinellid sponges that has only subacicular hooks, with F. cyrtauloni sp. nov. as its type species. Nine new species are described in Eunice: E. hernandezi sp. nov., E. ibarzabalae sp. nov., E. mikeli sp. nov. and E. nonatoi sp. nov. all belonging to the fuscusbidentate group; E. edwinlinkae sp. nov., E. hartmanae sp. nov., E. lanai sp. nov., and E. miurai sp. nov. all belonging to the flavus-tridentate group; and E. donathi sp. nov. that belongs to the fuscus-unidentate group. Further, two new species are described in Marphysa: M. angeli sp. nov. that is grouped with species having only composite falcigers, and M. orensanzi sp. nov. that belongs to the group with composite falcigers and composite spinigers. A key to identify genera in Eunicidae is included. A key to identify species of Eunice is appended.

Terrestrial tardigrades were collected from moss, lichen and leaf litter from Grand Cayman in the Cayman Islands, West Indies. Six species were found. Milnesium tardigradum Doyère, 1840, Minibiotus intermedius (Plate, 1889), Paramacrobiotus areolatus (Murray, 1907) and P. richtersi (Murray, 1911) have been reported previously from other islands in the Caribbean Sea. Two species on Grand Cayman were new to science. Doryphoribius tessellatus sp. n. belongs to the ‘eveli- nae-group’, with two macroplacoids and cuticular gibbosities. In having two pairs of posterior gibbosities and cuticular depressions forming a reticular design, it is most similar to Doryphoribius quadrituberculatus Kaczmarek & Michalczyk, 2004 from Costa Rica. It differs from D. quadrituberculatus in its gibbosity sequence (III:4:2:2), the number of teeth, size of macroplacoids and details of the reticular design on the dorsal cuticle. Macrobiotus caymanensis sp. n. belongs to the ‘polyopus-group’ of species. It differs from other species of the group in having a shorter buccal tube, a more posterior stylet support insertion point and fewer, larger egg processes.

A new species of the genus Diopatra Audouin & Milne-Edwards, 1833 from the intertidal zone in the vicinity of the Smithsonian field station (Carrie Bow Cay, Belize) is described. Diopatra tuberculantennata sp. nov. is identifiable by a combination of characters such as the presence of large lateral projections on both palpophores and antennophores, bidentate pseudocompound hooks with moderately long pointed hoods in the first five chaetigers, eyespots on the prostomium, nuchal organs forming almost a circle and very large sensory papillae on antennostyles and frontal and upper lips. Five 28-chaetiger juveniles were found inside the parental tube of one specimen. A pattern of anterior segment regeneration is described based on 12 specimens. A key for 20 species of onuphids known from the Caribbean Sea with the notes on their distribution is provided.

Two new species of the genus Callochiton are described: C. sonchaensis sp. nov. from Vietnam and C. tongaensis sp. nov. from Tonga. They differ from other congeneric species in having a different number, shape, size and arrangement of grooves on the pleural areas of the intermediate and tail valves, the number of slits, the size of the dorsal spicules, and sometimes the coloration of the girdle. Absence of Callochiton in the Caribbean Sea and along the coasts of Central and North Americas was, perhaps, due to late advancement of species from this genus into the Tethys from the regions near Gondwana.

Thirteen species of the Western Atlantic genus Hypoplectrus (Serranidae) are currently recognized, two of which are described as new. Hypoplectrus maya n. sp. (Maya hamlet) is restricted to the coastal lagoon of the Meso-American Barrier Reef system in Belize. It is a solid iridescent blue, lacks nose spots and lacks black margins on fins. Hypoplectrus randallorum n. sp. (Tan hamlet) is found widely in the central and western Caribbean. Its color varies from light brown to tan and it has spots on the nose, at the base of the pectoral fin and occasionally on the upper part of the caudal peduncle. All identified species of Hypoplectrus are illustrated in live coloration along with examples of color variations in H. nigricans and H. unicolor. A historical review of Hypoplectrus is included with a discussion of issues concerning their taxonomy.
