Original Type

The species of the widespread gorgoniid genus Leptogorgia, which occur along the eastern Pacific, are taxonomically revised based on original type material of all species described until now and reference specimens from recent surveys and expeditions along the Pacific coast of Panama, and Costa Rica. As a result, 21 species are recognized as valid and one as dubious. Lectotypes are assigned for eight species in order to establish their taxonomic status. All the species are described and illustrated. The fauna herein reported does not represent overall diversity or geographical range of each species but adds new reports. The present count is 16 species for Panama, 11 for Costa Rica, 7 for Mexico, 6 for El Salvador, 4 for Peru, 4 for Ecuador, 3 for Colombia, 2 for California, 2 for Nicaragua, and 2 for Chile.

Excavating sponges are one of the main groups of bioeroders in coral reefs. Their diversity has been thoroughly studied in some regions: in the Caribbean, the Mediterranean, and the Indo-Pacific, including the Mexican Pacific. However, there is a lack of information from the Pacific of Central America, with only a few records from Panama and Costa Rica. This study provides additional distributional records and taxonomic descriptions of species collected between 2011 and 2016 at nine localities along the Pacific coast of El Salvador, Nicaragua, Costa Rica and Panama. A total of fourteen species of excavating sponges from three orders, three families, and five genera are considered valid in this area. Nine are new records for Central America, six are new records for El Salvador, three are new records for Nicaragua and eleven are new records for Costa Rica. The species collected from Panama were already recorded before. The species here described are Cliona amplicavata, Cliona californiana, Cliona euryphylle, Cliona microstrongylata, Cliona aff. mucronata, Cliona pocillopora, Cliona tropicalis, Cliona vermifera, Cliothosa tylostrongylata, Pione cf. carpenteri, Pione mazatlanensis, Thoosa calpulli, Thoosa mismalolli and Siphonodictyon crypticum. We also reviewed the literature related to excavating sponges from Central America, and the taxonomic status of respective species was updated. We provide a faunistic record of 14 excavating sponge species for Central America. Our data are expected to be useful for management and conservation purposes.  

A revision of the genus Heterogorgia Verrill, 1868 (Anthozoa: Octocorallia: Plexauridae) ODALISCA BREEDY (Costa Rica) & HECTOR M. GUZMAN (Republic of Panama)

Pacific Species

The genus Heterogorgia Verrill, 1868 is poorly known. Lack of good illustrations and clear definitions have historically led authors to assign or transfer species erroneously to it. The genus was established by Verrill for three eastern Pacific species, another was described by Breedy and Guzman in 2005, and the geographic distribution was extended with the discovery of a western Atlantic species described by Castro in 1990. Heterogorgia is characterised by colonies composed of a number of stout stems that branch laterally and irregularly and arise from a conspicuous spreading holdfast. Coenenchymal sclerites are mostly colourless spindles; anthocodiae have strong spindles arranged in collaret and points; and the calyces are prominently armed with whorls of strongly projecting thorns. To define Heterogorgia we examined original type material of all eastern Pacific and western Atlantic species described until now and reference specimens from recent expeditions along the eastern Pacific. Morphological characters are analysed and illustrated using scanning electron micrographs. Lectotypes are designated for H. tortuosa and H. verrucosa to establish their taxonomic status. We conclude that Heterogorgia is comprised of five valid species at present: Heterogorgia hickmani and H. verrucosa for the Galapagos Islands and Ecuador mainland; H. papillosa for Mexico; H. tortuosa and H. verrucosa for Costa Rica and Panama; and H. uatumani for Brazil and Bahamas. The genera Astromuricea, Bebryce, Echinogorgia and Psammogorgia are proposed for the western Pacific species that were historically misplaced in Heterogorgia. We recommend that regional biodiversity estimates and biogeography analyses consider the erroneous status of the species that are still listed as Heterogorgia within the data sets.

An account is given of the names of families, genera, and species of hydroids established by C.M. Fraser of Canada, excluding those from Allan Hancock Pacific Expeditions and the Allan Hancock Caribbean Sea Expedition. The names of four families, 11 genera, and 101 species are attributed to him in this work, complementing those of another two genera and 164 species described by Fraser in various Allan Hancock publications. Information is provided on type localities of his new species, on locations and kinds of type material in existence, where known, and on the current taxonomic status of families, genera, and species described by him in works reviewed herein. Two replacement names (Thuiaria geniculata Fraser, 1918a and Salacia fraseri Calder, 1991) exist for Thuiaria distans Fraser, 1914a (not Thuiaria distans Allman, 1877). The widely overlooked senior synonym, T. geniculata, is recognized as the valid name of the species. Diphasia alta nom. nov. is proposed as a new replacement name for the permanently invalid junior primary homonym Diphasia robusta Fraser, 1943a (not D. attenuata robusta Billard, 1924). In addition, Cryptolaria crassa nom. nov. is proposed as a new replacement name for the junior secondary homonym Cryptolaria rigida (Fraser, 1948) [not C. rigida (Fraser, 1940a)]. Lectotypes have been designated for 47 of the species to establish objective standards for application of their names. Corymorpha adventitia Fraser, 1941b, from the Pacific coast of Panama, is assigned to Ralpharia Watson, 1980, as R. adventitia. No type specimens are known to exist for seven of the species considered, including one holotype (of Hebella eximia Fraser, 1944a) missing from its bottle. Particular attention has been paid to dating and chronology of the 51 publications of Fraser covered in this work. Earlier bibliographic errors are corrected, most notably establishing that the book Distribution and relationship in American hydroids was published in early 1947 rather than 1946 as per the title page.

Summary Parasitological examination of a stranded hawksbill turtle (Eretmochelys imbricata) from Pacific coast of Costa Rica revealed the presence of a rich digenean fauna including Carettacola stunkardi (Spirorchiidae), Enodiotrema reductum (Plagiorchiidae), Cricocephalus albus, Adenogaster serialis, Epi-bathra crassa, Pleurogonius lobatus, P. trigonocephalus, P. linearis, and Pyelosomum posterorchis (Pronocephalidae). All helminths except C. albus and P. lobatus represent new geographical records for Costa Rica. Carettacola stunkardi is reported for first time in an Eastern Pacific hawksbill turtle and its pathological changes are here described. Histologically, nodular lesions on the serosal surface of intestine revealed a mixed infiltrate of heterophils, lymphocytes, and histiocytes within necrotic debris. Granulomas with spirorchiid eggs were observed in the mucosa, sub-mucosa and muscular layers of stomach and intestine, gallbladder and liver.

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.
