Cyclopid copepods are frequently found in freshwater and transitional habitats. Members of the subfamily Halicyclopinae are chiefly brackish water forms with a few freshwater species. The new species described herein is assignable to the group of species "F" of Halicyclops (sensu Pesce, 2018) with a 2333 exopodal spine formula. Currently, this group contains five species and one subspecies. Halicyclopsgutierrezi sp. n. can be distinguished from its known congeners by the absence of an anal operculum, the relative length of setae of the female and male P5, the relative length of the inner setae of P4EXP3, and details of the male antennule. This is the fifth species of Halicyclops recorded from Colombia and the first one of Halicyclops group "F" described from the Caribbean region. With the addition of H. gutierrezi sp. n., the number of species of the genus known from the Neotropics increased to 20. A key to the species of the genus recorded in Colombia is also provided.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN Muestras de plancton obtenidas de la Ciénaga Grande de Santa Marta, un extenso sistema estuarino en el norte de Colombia, produjeron especímenes machos y hembras de una especie no descrita del género Halicyclops. Los copépodos de la familia Cyclopidae son dominantes en los hábitats de agua dulce y transicionales. Los miembros de la subfamilia Halicyclopinae son predominantemente de hábitats salobres, con algunas especies de agua dulce. La nueva especie aquí descrita es asignable al grupo de especies denominado "F" de Halicyclops (sensu Pesce, 2018) con una fórmula de espinas exopodales (P1-4) = 2333. Actualmente, este grupo contiene cinco especies y una subespecie. Halicyclops gutierrezi sp. n. puede distinguirse de sus congéneres conocidos por la ausencia de un verdadero opérculo anal, la longitud relativa de las setas de la P5 de la hembra y del macho, la longitud relativa de las setas internas de P4EXP3 y por detalles de la anténula del macho. Esta es la quinta especie de Halicyclops registrada en Colombia y la primera del grupo "F" de Halicyclops descrita en la cuenca del Caribe. Con la adición de H. gutierrezi sp. n., aumentó a 20 el número de especies del género que se conocen en la región Neotropical. Se proporciona una clave para la identificación de las especies del género registradas en Colombia.]]></p></abstract>
