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.

<p>The molluscan fauna of Isla del Coco has recently been well documented, but the heterobranch sea slugs, traditionally called “opisthobranchs”, remain poorly known. We report 13 new records, increasing the total to 40 species. Of the 13 newly discovered species, the following species had not been previously recorded along the Pacific Costa Rican mainland: <em>Berthella californica </em>(Dall, 1900), <em>Peltodoris rubra</em> (Bergh, 1905), <em>Dendrodoris albobrunnea </em>Allan, 1933, <em>Doriopsilla</em> cf. <em>spaldingi </em>Valdés &amp; Behrens, 1998, <em>Glaucus</em> cf. <em>marginatus</em> (Reinhardt &amp; Bergh, 1864), and <em>Flabellina</em> sp. Additionally, we report <em>Peltodoris rubra</em>, previously known from the Indo-Pacific, for the first time in the Eastern Tropical Pacific.</p><div> </div>

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.

A New Species

A redescription of Pagurus albus (Benedict, 1892) is presented together with a description of a new species of hermit crab, Pagurus pseudoalbus sp. n., from the Pacific coast of Costa Rica. Pagurus pseudoalbus sp. n. differs from P. albus and P. perlatus by the length of antennal acicles, which do not exceed the distal margin of the 4th antennal segment, whereas in the latter two species, the antennal acicles exceed the 4th antennal segment; the antennular peduncle is proportionally longer than the ocular peduncle in the new species compared to P. perlatus, but shorter than in P. albus; the palm of the right cheliped in P. pseudoalbus sp. n. is 1.3 times as long as broad, while in P. albus and P. perlatus it is 1.0 and 1.4 times as long as broad, respectively. Including the new species, the genus Pagurus in the Eastern Tropical Pacific currently includes 16 species.

We report new records of four macroalgae species in the Eastern Tropical Pacific, specifically from the rocky reefs of northern Choc&oacute;, Colombian Pacific. Among them, three species of Rhodophyta are included&mdash;Crouania mageshimensis Itono, 1977; Monosporus indicus B&oslash;rgesen, 1931; Jania articulata N&rsquo;Yeurt &amp; Payri, 2009&mdash;and one species of Chlorophyta&mdash;Ulothrix subflaccida Wille, 1901. The new records increase the knowledge of tropical marine algae in the Pacific, open the discussion about possible dispersal mechanisms, and recall the importance of conducting molecular studies to define phylogenetic and biogeographic aspects of macroalgae.

Euphausiids have been well studied in several regions of the Pacific Ocean; however, there is lessinformation regarding euphausiids in Costa Rican waters. We analyzed euphausiid specimens collected aroundIsla del Coco National Park during 2011 and 2012. A total of 130 specimens were analyzed and 13 euphausiidspecies were identified, belonging to four genera and one family. An annotated list of species is presented,with photographs and details for their identification. All species found represent new records for waters aroundIsla del Coco in the Costa Rican Pacific. The most frequent species were Euphausia diomedeae, Euphausiadistinguenda, Nematoscelis gracilis and Stylocheiron affine. Rev. Biol. Trop. 64 (Suppl. 1): S221-S230. Epub2016 Febrary 01.

Four new shallow water species of the genus Pacifigorgia were found in recent surveys along the Pacific coast of Panama. One of the species was only found in dense patches at two shallow seamount-like localities inside the Coiba National Park, Gulf of Chiriqu . Two other species were patchily distributed at several localities in the Gulf of Chiriqu . A fourth species was widely distributed around the gulfs of Chiriqu and Panama encompassing a broad range of habitats and depths. The new species are described and illustrated in detail with scanning electron micrographs (SEM) of the sclerites, and colour photographs of the colony forms. The suspected occurrence of a particular Pacifigorgia species for this region is confirmed and two other new records are added to the species list. With the new four species, a total of 15 are established for Panama, making 31 species for the eastern Pacific to date.
