<body><![CDATA[<p><i>KEY WORDS:</i>  Systematics, Taxonomy, Peanut worms, Cosmopolite species, Synonymies.</p> <hr>     <p><b>INTRODUCCI&Oacute;N</b></p>      <p>El phylum Sipuncula es un peque&ntilde;o grupo de invertebrados que comprende animales con una segmentaci&oacute;n no evidente, son vermiformes, celomados y protostomados con simetr&iacute;a bilateral (Murina, 1984). Se les conoce com&uacute;nmente como "gusanos cacahuate" o "gusanos man&iacute;", dada la apariencia que tienen una vez contraen el cuerpo, el cual est&aacute; dividido en introverto y tronco (Spongberg, 2006).</p>      <p>Los sip&uacute;nculos comprenden dos clases, seis familias y 17 g&eacute;neros, con 150 especies conocidas. Son exclusivamente marinos y se distribuyen ampliamente desde aguas tropicales hasta polares, en un gradiente que comprende la zona intermareal hasta la abisal. En su mayor&iacute;a se encuentran en lugares con lodo, limo y arena, donde se alimentan de material particulado del cual extraen nutrientes, algas y otros organismos. Algunas especies buscan protecci&oacute;n en conchas de moluscos y tubos de poliquetos (Schulze, 2005; K&#281;dra y Murina, 2007).</p>      <p>Los sip&uacute;nculos, tambi&eacute;n llamados sipunc&uacute;lidos, desempe&ntilde;an un papel importante en el proceso de desgaste de los arrecifes de coral y las rocas blandas; son erosionadores biol&oacute;gicos (organismos encargados del proceso de desgaste de sustratos duros), al igual que constituyen una fuente de alimento para an&eacute;monas, gaster&oacute;podos, cefal&oacute;podos, cangrejos y peces y, en algunos casos, humanos. No obstante, es un grupo pobremente estudiado en cuanto a su taxonom&iacute;a y ecolog&iacute;a (K&#281;dra y Murina, 2007; Dom&egrave;nech <i>et al.</i>, 2008; K&#281;dra y Wiodarska-Kowalczuk, 2008).</p>      <p>De acuerdo con Cutler (1994), Rondelet fue el primero en estudiar los sip&uacute;nculos en 1555, y se encarg&oacute; de hacer las primeras ilustraciones. Luego, Bohadsch (1761) les dio el nombre de <i>Syrinx</i>  y los incluy&oacute; como un nuevo grupo animal dentro de los zoofitos. A principios del siguiente siglo, Rafinesque-Schmaltz (1814) propuso el nombre de la familia Sipuncula para <i>Syrinx</i> dentro de la clase Proctolia, donde incluy&oacute; gusanos no segmentados con intestino completo. Lamarck (1816) los ubic&oacute; dentro de los equinodermos, mientras que Delle-Chiaje (1823) sugiri&oacute; incluirlos dentro de los an&eacute;lidos, bajo el nombre de Sipunculacei. Posteriormente, Quatrefages (1847) los agrup&oacute; junto con equiuros y priapulos, y los nombr&oacute; <i>Gephyrea</i>. A finales de ese mismo siglo, Sedgwick (1898) propuso que se les reconociera como el phylum Sipunculoidea, por alguna raz&oacute;n el nombre no fue adoptado y se les sigui&oacute; llamando <i>Gephyrea</i>  hasta mediados del Siglo XX; el nombre aceptado fue dado por Stephen (1965) quien los llam&oacute; Sipuncula. Cutler y Gibbs (1985) y Gibbs y Cutler (1987) establecieron el nombre del phylum como Sipuncula, agrup&aacute;ndolo en dos clases, cuatro &oacute;rdenes, seis familias y 17 g&eacute;neros, teniendo en cuenta estudios filogen&eacute;ticos. No obstante, la posici&oacute;n filogen&eacute;tica actual del grupo es dudosa; se les ha relacionado estrechamente con Mollusca, Annelida (Schulze, 2005) y Echiura (Edgecombe <i>et al.</i>, 2011), teniendo en cuenta las similitudes morfol&oacute;gicas entre estos grupos (D&iacute;az-D&iacute;az, 2011). Las relaciones con los an&eacute;lidos se basan en evidencia gen&eacute;tica de acuerdo con la disposici&oacute;n de los genes de ADN mitocondrial y an&aacute;lisis en las secuencias de ADN nuclear (Schulze <i>et al</i>., 2007). Recientemente, Edgecombe <i>et al.</i> (2011) establecieron que Sipuncula es un tax&oacute;n dentro del phylum Annelida, junto con los taxones Echiura, Pogonophora y Vestimentifera, usando an&aacute;lisis moleculares para establecer dichas relaciones evolutivas. No obstante, Kawauchi <i>et al.</i>  (2012) propusieron una nueva clasificaci&oacute;n para el phylum, bas&aacute;ndose en el an&aacute;lisis filogen&eacute;tico de seis genes. La nueva clasificaci&oacute;n incluye 16 g&eacute;neros dentro de seis familias.</p>      <p>Existen varias razones por las que el grupo ha sido pobremente estudiado, entre ellas, la falta de tax&oacute;nomos especialistas en el mundo. Actualmente, hay menos de diez especialistas que trabajan con sip&uacute;nculos; adem&aacute;s, la identificaci&oacute;n de las especies no es sencilla, pues es necesaria la disecci&oacute;n para la identificaci&oacute;n de la mayor&iacute;a de las especies (K&#281;dra y Wiodarska-Kowalczuk, 2008). Por lo tanto, debido a la poca informaci&oacute;n taxon&oacute;mica que existe sobre los sip&uacute;nculos, se hizo una revisi&oacute;n de la literatura teniendo en cuenta todos los registros del phylum en el Gran Caribe, con la intenci&oacute;n de brindar una herramienta de b&uacute;squeda, y un valioso aporte para el conocimiento de la fauna marina del Gran Caribe. La literatura citada en el presente trabajo proviene de las investigaciones realizadas en el Caribe. Salazar-Vallejo (2000) considera al Gran Caribe como una regi&oacute;n que comprende desde el Estado de Carolina del Sur, hasta el litoral norte de Brasil, incluyendo el Golfo de M&eacute;xico, las Antillas Mayores y Menores, as&iacute; como las costas de Centro y Sur Am&eacute;rica, dentro de este l&iacute;mite.</p>      <p><b>MATERIALES Y M&Eacute;TODOS</b></p>      <p>Se realiz&oacute; un listado para los registros de especies de sip&uacute;nculos presentes en el Gran Caribe mediante la b&uacute;squeda de publicaciones electr&oacute;nicas e impresas relevantes. As&iacute; mismo, se tuvieron en cuenta aquellas referencias, desde las m&aacute;s antiguas hasta las m&aacute;s recientes, que trataban al grupo desde el punto de vista morfol&oacute;gico.</p>      <p>Las familias, los g&eacute;neros y las especies se ordenaron alfab&eacute;ticamente y no en orden filogen&eacute;tico, como es usual en la mayor&iacute;a de trabajos de este tipo, con el fin de facilitar la b&uacute;squeda de los nombres de los diferentes taxones. Al final de cada tax&oacute;n se adicionaron las citas bibliogr&aacute;ficas donde se habla de &eacute;l. Las referencias correspondientes a cada cita se encuentran en la secci&oacute;n de bibliograf&iacute;a. Aquellos registros de taxones no descritos o indeterminados (<i>e.g</i>: <i>Golfingia</i> sp., <i>Aspidosiphon</i> sp.) no se incluyeron en el listado taxon&oacute;mico; de igual forma, se omitieron aquellos registros que aparecen como "<i>cf.</i> " (del lat&iacute;n <i>confer</i>: comparar con) por su imprecisi&oacute;n y por carecer de adecuada informaci&oacute;n (Ejemplo: <i>Nephasoma</i>  cf. <i>eremita</i>).</p>      ]]></body>
<body><![CDATA[<p>La letra <i>C</i>  (del t&eacute;rmino <i>Cuestionable</i>) se utiliz&oacute; en aquellas especies de las cuales se tiene duda de su distribuci&oacute;n en el Gran Caribe, debido a que su localidad tipo est&aacute; por fuera de esta regi&oacute;n. Para corroborar la autor&iacute;a de las especies y los nombres v&aacute;lidos se tuvo en cuenta la informaci&oacute;n publicada en la base de datos WoRMS (2013) y consultando principalmente la revisi&oacute;n hecha por Cutler (1994).</p>      <p><b>RESULTADOS</b></p>      <p>Se encontr&oacute; en la literatura consultada que para el Gran Caribe se han registrado un total de 84 nombres, de los cuales 23 corresponden a nombres de especies v&aacute;lidas y 55 a nombres de especies nominales. No se encontr&oacute; informaci&oacute;n para diez combinaciones de nombres al consultar WoRMS (2013).
