C omo parte de un monitoreo durante el año 2016 en una bahía estuarina interna en Cartagena, Colombia, se recolectó e identificó un ejemplar hembra adulto de Cymbasoma chelemense. Esta especie fue descrita originalmente para el Golfo de México y comparte las siguientes características morfométricas y morfológicas: Cefalotórax de al menos 68% del total de la longitud del cuerpo; papila oral localizada en al menos 20% de la longitud total del cefalotórax; ocelo presente; el complejo genital posee una espina ovígera posicionada en la base y un somite post-genital sencillo, la espina ovígera es al menos 14% más larga que la longitud total del cuerpo y alrededor de 10 veces la longitud del urosoma. Este es el primer registro de un copépodo del género Cymbasoma en aguas estuarinas colombianas extendiendo el ámbito geográfico de esta especie en el mar Caribe.
A New Species of Monstrilla (Copepoda, Monstrilloida) From the Mexican Coasts of the Caribbean Sea
Crustaceana, 1992
The genus Monstrilla Dana, 1849 is the most diverse of the copepod order Monstrilloida. Monstrilloid copepods are endoparasites of benthic polychaetes and molluscs; adult individuals are free-living, nonfeeding reproductive forms that briefly become part of the zooplankton community, where they are occasionally captured by plankton nets. Monstrilloid copepods are frequently found during routine plankton samplings of coastal and estuarine habitats, but they are rarely found in large numbers. The western sector of the Caribbean Sea is known to harbor a diverse monstrilloid fauna. The analysis of zooplankton samples obtained during nine years from Chetumal Bay, a large embayment of the Mexican Caribbean coast, yielded a male monstrilloid that was found to represent a new species. It is herein described following upgraded standards and compared with its congeners. A key to males and females of the Monstrilla species known from the northwestern Caribbean is also provided.
Revision and update of the checklist of copepods (Crustacea: Hexanauplia) of the Colombian Caribbean

The aim of the study was to obtain a revised and updated checklist of the species of copepods of the Colombian Caribbean. Methods for updating included a critical compilation of records in published and unpublished articles, and our own results of a study of zooplankton in a project on bioinvasions of coastal waters, conducted in 2010. Twenty taxa reported solely in undergraduate thesis need taxonomical comprobation and were excluded from the inventory. As a baseline, we used the most recent inventory published by Medellín-Mora and Navas (2010). Ten species recorded in the already mentioned project are new records. Thirteen species reported by other researchers in publications after 2010 increased the species list. The inventory totals 214 species of copepods (158 Calanoida, 38 Cyclopoida, 15 Harpacticoida, 2 Mormonilloida and 1 Monstrilloida). Most species are planktonic (201), while only a few are benthic (10) or epibenthic (3). Nomenclature of the taxa was revised and updated as well. The highest copepod diversity corresponds to the ecoregion Colombian Oceanic (127 species), followed by Tayrona (94), Magdalena (82) and Morrosquillo (78). The lowest number corresponds to San Andrés and Providencia Archipelago (49). The limited information existing about benthic and parasitic copepods warrants an increment on the study these groups. Most of them belong to orders Harpacticoida and Siphonostomatoida.

Plankton samples obtained from the lagoon system Laguna Navío Quebrado, in northern Colombia, yielded male and female specimens of an undescribed cyclopoid copepod of the genus Halicyclops. The new species belongs to the highly diverse and widely distributed thermophilus-complex. It closely resembles Halicyclopsclarkei Herbst, 1982 from Louisiana and Halicyclopsbowmani Rocha & Iliffe, 1993 from Bermuda. These species share the same armature of P1-P4EXP3, with a 3443 spine formula and the terminal antennary segment with 5 setae. However, Halicyclopsgaviriai sp. n. can be separated from both Halicyclopsclarkei and Halicyclopsbowmani by the morphology of the anal pseudoperculum, the proportions of the fourth antennulary segment, the length of the inner basipodal spine of P1, the P1EXP/inner basipodal spine inner length ratio and the length/width ratio of the caudal rami. This is the third species of Halicyclops recorded from Colombia and the first one described from this country. With ...

Resumen. Especímenes del género Cyclopina Claus 1863 fueron colectados durante el desarrollo de un proyecto de investigación en el sistema Urías (sur de Sinaloa, México). Análisis preliminares indicaron gran semejanza entre estos especímenes de Cyclopina y C. caissara Lotufo 1994, y debido a la distribución conocida de esta última especie (registrada sólo en São Sebastião, Brasil, su localidad tipo), se pensó que era probable que los especímenes del sistema Urías representaran una nueva especie. Sin embargo, después de realizar análisis y comparaciones detalladas del material tipo de C. caissara y los especímenes mexicanos, no se observaron diferencias significativas que justificaran la descripción de una nueva especie. Este trabajo constituye el primer registro del género para sistemas costeros mexicanos, y el hallazgo de C. caissara en la boca del Golfo de California representa una extensión de su distribución desde Brasil hasta el Pacífico Oriental Subtropical. Se presentan también algunas correcciones a la descripción original de la especie.

The Southern Caribbean (SCA) represents the most productive ecoregion of the Tropical Northwestern Atlantic (TNWA) province. In order to assess the diversity of pelagic copepods in the ecoregion, we present an inventory based on unpublished data obtained from several oceanographic cruises made in oceanic and neritic waters of Venezuela (1967-1968). We complement this information with previous regional surveys to obtain a revised systematic checklist of the pelagic copepod species in the SCA. We included in our list a total of 346 species and 2 subspecies; up to 11 species represent new records. This study allowed us to: 1) expand the distributional range of some species within the TNWA, 2) record the occurrence, in the SCA, of all species known to 12 of 42 families to occur in the TNWA, 3) determine that the number of species of Corycaeidae and Paracalanidae in the SCA is greater than previously documented for the TNWA. Overall, the species accumulation curve resulting from our data...

Sixteen species of planktonic copepods are reported from Laguna de Navío Quebrado, La Guajira, Colombia. Zooplankton samples were collected from the littoral zone with vegetation (macrophytes and mangroves) and from open water related to an oyster bank. Most of these species were recorded in the macrophytes-related area. One of them: Halicyclops exiguus Kiefer, 1934 is new to the Colombian copepod fauna; comparative morphological comments and illustrations of this species are also provided. The general composition of the local copepod community, including marine, estuarine and freshwater forms is representative of the wide salinity gradient (0-28) found in the surveyed area. This is the fist report on the planktonic copepod fauna in this hydrological system. Comments on the morphology and photographs of selected species are provided.

Objectives: to report the first record of C. sinaloensis for Colombia. Scope: to present a brief description of this material in order to support the identification of the newly found material. Methodology: Water samples were taken at Ciénaga Grande de Santa Marta Colombia using a 25 L bucket. Samples were filtered with a standard zooplankton net (45 μm mesh) and fixed and preserved in 70% ethanol. Harpacticoid copepods were separated with a brush. Dissected specimens and appendages were mounted in glycerine. The dissected appendages were photographed using a Kodak Easy Share C140 digital camera adapted to a compound microscope at a magnification of 1000X. Main results: Cletocamptus sinaloensis seems to be closely related to C. levis Gómez 2005, known from Brazil. The closeness of these species was assumed based on the general shape and number of setae of the mandibular palp (one-segmented with three setae), P2-P4 EXP3 and ENP2 with 5-5-4 and 3-3-2 elements respectively, length: wid...
