New records of occurrence for four species lampriform fishes (Teleostei: Lampriformes; Desmodema polystictum, Regalecus russelii, Trachipterus fukuzakii and Zu cristatus) poorly known or previously unknown the Pacific coast lower Central America (Costa Rica-Panama) are herein reported. Museum specimens supporting such characterized described. Comparative morphometric meristic data on other collections lampriforms, as well distributional information, provided discussed. Diversity, taxonomy...
An annotated catalog of the type specimens deposited at fish collection “Universidade Estadual Paulista, Câm-pus de São José do Rio Preto”, Paulo, Brazil (DZSJRP), is herein presented for consultation and scientific information. The DZSJRP comprised by 154 lots 4,993 specimens, 18 which are holotypes, include a total 53 species in six families. For each species, following data provided: current valid name, authority year description, locality holotype number (for those hosted DZSJRP), list...
A new species of Chimaera Linnaeus 1758 is described from three specimens collected off the Pacific coasts Costa Rica and Peru. orientalis n. sp., first genus eastern Ocean, distinguished its other congeners by a combination coloration morphology. Additionally, records occurrence for another four chimaeroid fishes (Harriotta raleighana (Goode & Bean 1895), Rhinochimaera africana Compagno, Stehmann Ebert 1990, Hydrolagus colliei Lay Bennett 1839, H. macrophthalmus de Buen 1959) previously...
Based on a combination of intensive literature review, electronic database searches, re-identification museum specimens and fieldwork, we hereby provide an updated checklist the freshwater fishes continental insular Costa Rica. This checklist, systematically arranged at ordinal familial level, includes nomenclatural revisions, distributional information, when appropriate, cross-references basis Bussing (1998). According to our results, native Rican fish fauna is composed by 250 species,...
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for fishes. Our NEOTROPICAL FRESHWATER FISHES data set is to produce a large-scale inventory, covering entire from Mexico and Caribbean in north southern limits Argentina, Paraguay, Chile, Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, represented by occurrence abundance data. number of species numerous orders are as follows: Characiformes...
Abstract A new species of trematode anaporrhutine gorgoderid, from the gill chambers Munda round ray Urotrygon munda in Costa Rica is described, based on an integrative taxonomic approach that includes use light and scanning electron microscopy, ITS2 28S rDNA sequencing, phylogenetic analysis. Anaporrhutum mundae sp. nov. can be distinguished congeneric by a combination morphological traits particularly having genital pore opening at level intestinal bifurcation. The also all other , except...
An annotated and photographically illustrated checklist with DNA barcodes of the species bony fishes collected during a month-long research cruise Spanish Research vessel B/O Miguel Oliver is presented. The made trawls on continental shelf Pacific coast Central America, in November-December 2010, at depths 108-1625 m. This list, based 707 specimens (of total 876 whole expedition), includes 129 belonging to 15 orders, 61 families, 97 genera. New information presented geographical...
Understanding key aspects of the biology and ecology chondrichthyan fishes (sharks, rays, chimaeras), as well range threats affecting their populations is crucial given rapid rate at which some species are declining. In Eastern Tropical Pacific (ETP), lack knowledge, unreliable (or nonexistent) landing statistics limited enforcement existing fisheries regulations has hindered management conservation efforts for species. This review evaluated our current understanding Costa Rican...
Dedicated ichthyological surveys in two karstic caves Costa Rica resulted the discovery of hypogean populations from three epigean species catfishes genus Rhamdia . The taxonomic identity these was initially determined based on morphological traits and subsequently corroborated with comparative DNA sequence data a phylogenetic framework. Individuals all documented herein exhibit only partial troglomorphism, characterized by moderate (vs. complete) integumentary depigmentation without extreme...
Central America contains a rich diversity of freshwater habitats that support more than 600 species fishes. However, despite several perceived threats to the integrity throughout region, formal analysis extinction risk for region’s ichthyofauna is lacking. In this manuscript, we report an updated checklist and novel comprehensive assessment conservation status American fishes by applying IUCN Red List Categories Criteria at global level. We also analyze distribution across generate baseline...
A checklist of the marine and estuarine fishes inner part Gulf Nicoya, Pacific coast Costa Rica, Central America, was compiled by examining a museum fish collection, resulting in 72 families 274 species. Of these species, 127 (46.4%) were species 147 (53.6%) estuarine-associated In terms their life history considering habitat type classification, 188 (almost 70% total) categorized as inhabiting soft-bottom habitats, reflecting large environment rich diversity despite its relatively small...
The Tropical Indo-Pacific (TIP) includes about two thirds of the world’s tropical oceans and harbors an enormous number marine species. distributions those species within region is affected by habitat discontinuities oceanographic features. As well as many smaller ones, TIP contains seven large recognized biogeographic barriers that separate Red Sea Indian Ocean, from Pacific central eastern Pacific, Hawaiian archipelago, Marquesas Easter Islands. We examined genetic structuring populations...
New records of occurrence two snipe eels (Avocettina bowersii and Nemichthys scolopaceus), poorly known for the Pacific coast Costa Rica Panama are herein reported. Specimens, 45 in total (28 17, respectively), were collected between 1972 1973 at depths 295 1000 m. Descriptions based on specimens as well comparative morphometric distributional information by species presented discussed. A key to identification eastern family also is presented. These findings increase knowledge Central...
Introducción: El conocimiento sobre la composición taxonómica de fauna peces agua dulce Costa Rica ha cambiado sustancialmente en las últimas dos décadas. No solamente por adición nuevas especies y táxones supra-específicos, sino también reordenamientos cambios taxonómicos los diferentes niveles jerárquicos. Las claves taxonómicas disponibles se publicaron hace más 20 años están desactualizadas. Objetivo: Brindar información actualizada, lenguaje sencillo, para identificación todas familias...
Stelliferinae is the third most speciose subfamily of Sciaenidae, with 51 recognized species arranged in five genera. Phylogenies derived from both morphological and molecular data support monophyly this subfamily, although there no general consensus on intergeneric relationships or diversity group. We used barcoding region cytochrome oxidase C subunit I (COI) gene to verify delimitation based Automatic Barcode Gap Discovery (ABGD), Generalized Mixed Yule Coalescence (GMYC), Bayesian Poisson...

Methods: We constructed a haplotype network...
A new species of Brycon is described from the Atlantic slope Nicaragua and Costa Rica. costaricensis n. sp. differs all other Central American by following combination characters: 49 to 54 scales in lateral line; 5 or 6 rows between line pectoral fin base; 9 11 dorsal 7 anal notably longer than head, with 33 37 total rays; a elongated shallow caudal peduncle, whose length 1.78 2.35 times its depth. key lower Mesoamerican genus also presented.
Abstract The gross morphology of the brain Rineloricaria heteroptera and its relation to sensory/behavioural ecology species is described discussed. sexual ontogenetic intraspecific variation in whole length mass, as well within/between eight different subdivisions volumes, also examined Negative allometry for length/mass relative growth telencephalon optic tecta was observed. Positive observed olfactory bulbs medulla oblongata . Univariate multivariate statistical analyses did not reveal...
Species with wide geographic distributions can consist of different lineages or even species. The present study evaluated the molecular diversity family Eleotridae by analyzing sequences COI gene from species collected in locations a Neotropical region as well BOLD and GenBank. analysis revealed distinction differentiation variety high statistical support, including Gobiomorus dormitor (two lineages), Dormitator maculatus (three lineages) Eleotris fusca number Microphilypnus.
