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.

Philoscia Muscorum

Examination of a small collection of Oniscidea from Costa Rica revealed the presence of two species new to science (Ischioscia martinae sp.nov. and Scleropactes talamancensis sp.nov.). Further specimens from the collection of the United States National Museum were reexamined to reconsider the status of Philoscia muscorum (Scopoli, 1793) and Ischioscia variegata (Dollfus, 1893), both of which have been reported from Costa Rica. The specimens belong to two new species (Ischioscia muelleri sp.nov. and Ischioscia elongata sp.nov.). Redescriptions of Ligia baudiniana Milne Edwards, 1840 from the shores of both the Caribbean Sea and the Pacific Ocean and the type material of Ischioscia variegata (Dollfus, 1893) from Venezuela are also presented.

Two new species of Pleurothallis subsection Macrophyllae-Fasciculatae from Costa Rica are described and illustrated, and their relationships discussed. Pleurothallis pudica, from the central Pacific mountain region, is compared with P. phyllocardia, but it is easily recognized by the densely pubescent- hirsute flowers. Pleurothallis luna-crescens, from the Caribbean slope of the Talamanca chain, is compared with P. radula and P. rectipetala, from which it is distinguished by the dark purple flowers and the distinctly longer, dentate petals, respectively. A key to the species of the group in Costa Rica and western Panama is presented.

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.

Hexactinellid Sponges

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.

Abstract: Seven species of terrestrial isopods are recorded from the coasts of the Pacific and Caribbean sides of Costa Rica. Three species (Buchnerillo neotropicalis, Hawaiioscia nicoyaensis and Trichorhina biocellata) are described as new and two species (Tylos niveus and Armadilloniscus cf. caraibicus) are newly recorded from the country. The poorly known species T. niveus is also illustrated. At present the total number of terrestrial isopod species recorded from Costa Rica is 30. Interestingly four typical littoral halophilic species (Ligia baudiniana, Tylos wegeneri, T. niveus and A. cf. caraibicus) are present on both the Pacific coast of Costa Rica and on the coasts of the lands encompassed by the Caribbean Sea. With the sole exception of A. cf. caraibicus, no morphological differences could be detected from the Pacific and Caribbean populations of those species. Rev. Biol. Trop. 66(Suppl. 1): S187-S210.

Eusocial Species

Sampling of eight sites along the west coast of Barbados, West Indies, yielded 14 species of sponge-dwelling shrimps in the gambarelloides group of the genus Synalpheus, including one new species described here as Synalpheus microneptunus n. sp. The new species is a member of the S. paraneptunus Coutière species complex and is distinguished from other species in that group by the combination of four carpal segments in the second pereopod, uropodal exopod with 2 nd distolateral tooth smaller than the other two teeth and set in line with movable spine, and a small blade on the scaphocerite. Synalpheus microneptunus n. sp. is the smallest species in the complex (2.2-2.9 mm CL) and lives in small colonies, usually with fewer than 10 individuals, often with a single breeding female. Synalpheus thele Macdonald, Hultgren & Duffy is reported for the first time from outside its type locality in Jamaica. Sampling in Barbados produced fewer species than did similar efforts in Jamaica and Curaçao, possibly due to the relatively isolated position of the island at the eastern (windward) edge of the Caribbean Sea.

Two new species of the genus Sarcofahrtiopsis Hall, 1933 are described: S. kuna sp. nov., which inhabits coastal mangroves along the Caribbean coast of Panama, and S. chiriqui sp. nov., which is found in the Pacific mangrove wetlands of southwestern Panama and in coastal northwestern Costa Rica. Both species have been collected from and breed in semiterrestrial crabs of the genus Cardisoma Latreille (Crustacea: Gecarcinidae). A key to species of Sarcofahrtiopsis is provided.

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.
