Seagrass meadows are declining worldwide, mostly attributed to anthropogenic disturbances. Understanding the dynamics of these meadows is urgent in order to establish adequate management and conservation strategies. Here, we analyzed the current knowledge on the seagrass meadows in the Caribbean and Pacific coasts of Costa Rica, Central America. Current knowledge was based on literature searches, herbarium collections, informal interviews, and personal observations. We report a total of five genera and seven species for Costa Rica: Thalassia testudinum, Syringodium filiforme, Halophila decipiens, Halophila baillonis, Halodule wrightii, Halodule beaudettei, and Ruppia maritima. Six species are reported for the Caribbean, and four species for the Pacific. Thalassia testudinum, S. filiforme, and H. decipiens have only been reported for the Caribbean. Halodule beaudettei has only been reported for the Pacific coast. Halophila baillonis, H. wrightii and R. maritima have been reported for both coasts. Seagrasses were found at a total of 31 locations in Costa Rica, most from the Pacific coast; 16 of which are reported here for the first time. Seagrass meadows from both coasts are vastly different. Along the Caribbean coast, meadows are often dominated by the robust T. testudinum, they are extensive and stable, persisting for decades. In contrast, the meadows along the Pacific coast are more dynamic and are dominated by pioneer and smaller ephemeral species, such as H. baillonis and H. beaudettei. The number of studies on Costa Rican seagrasses is scarce but has been increasing over time, and mostly concern taxonomic reports and basic descriptions of the dynamics of T. testudinum meadows from the Caribbean. Research, conservation and management efforts on Costa Rican seagrass meadows would benefit from continued monitoring and research on associated fauna and flora, incorporating ecosystem resilience and services.

A new canuellid, Microcanuella bisetosa gen. n., sp. n., was collected on the Pacific coast (Gulf of Nicoya) of Costa Rica. Though the male is still unknown, a new genus is established, mainly because of the reduced armature of P1, P4, and P5. The small-sized M. bisetosa sp. n. is a mesopsammic species, inhabiting the interstices of coarse sediments of a beach slope.

Soft Bottoms

Echinoderms within the Eastern Tropical Pacific have mainly been studied in association with coral reefs. Investigations on echinoderms associated with soft-bottoms and estuaries are still scarce. The present study reports on the echinoderm species inhabiting the soft-bottom sediments of shallow-brackish waters adjacent to the largest river basin along the Pacific coast of Costa Rica, Térraba-Sierpe wetland. Nine species were recorded, three of them new records for Costa Rica: Luidia columbia, L. latiradiata, and L. superba. The most common species were L. columbia, Astropecten armatus, A. regalis, and L. latiradiata. This contributes towards current knowledge on the biodiversity of Térraba-Sierpe wetland and should be considered as a baseline upon which to monitor the effects of future impacts on this important mangrove area.

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.

Primary Consumers

Although appendicularians are relevant primary consumers and are part of every zooplankton community, there is a lack of information on the species present in different ocean regions. Thus, regional identification guides are useful to develop datasets with high taxonomic resolution. Appendicularian species were identified in 33 epipelagic samples of zooplankton collected in several locations of Costarican waters. Eighteen appendicularian species were identified, of which 15 were found in the Pacific and only three in the Caribbean. Seven species are new records for Costa Rican Pacific waters (Appendicularia sicula, Fritillaria charybdae, F. cf. pacifica, F. tenella, F. pellucida f. omani, Oikoipleura fusiformis f. cornutogastra and Pelagopleura verticalis). Data for each species distribution in Costa Rica is presented together with a key for the identification of appendicularian species recorded in the Inter-American seas and the Eastern Tropical Pacific.

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.

In the present work was carried out in the intertidal zone of Las Baulas de Guanacaste National Marine Park (PNMB) located on the Pacific coast of Costa Rica.                The main objective was to contribute to knowledge about the invertebrate diversity of the park, one of the richest bioregions on the planet, about which little is known. This study assesses the Order Polycladida Lang, 1884, a cornerstone of this ecosystem and one of the most cosmopolitan and plastic invertebrate taxa in the animal kingdom.                In total, 57 individuals were collected in the rocky intertidal zone of Carbón and Langosta beaches. Nine different species were identified, of which four are new for Costa Rica: Semonia bauliensis n. sp.; Cryptostylochus sesei n. sp.; Paraplanocera angeli n. sp., Prostheceraeus fitae n. sp.; and five new records: Paraplanocera oligoglena (Schmarda, 1859); Marcusia ernesti Hyman, 1953; Enchiridium magec Cuadrado, Moro & Noreña, 2017; Pseudobiceros bajae (Hyman, 1953); and the genus Boninia spp.
