“…In the Americas, 33 species have been recorded, and up to 19 have been known to occur in the Caribbean region (Reid, 1990;Fiers, 1995;Rocha et al, 1998). The highly diverse Brazilian coast is known to harbor at least ten different species (Rocha, 1983a, Rocha, 1983bRocha, 1984;Lotufo and Rocha, 1993). Only four species are known from the United States Gulf Coast (Rocha and Hakenkamp, 1993), five species from Central America, and the Caribbean (Herbst, 1987;Reid, 1990;Fiers, 1995), including a record of H. exiguus Kiefer, 1934from Costa Rica (Collado et al, 1984, Morales-Ramírez et al, 2014 and three from anchialine caves in Bermuda (Rocha and Iliffe, 1993).…”

Plankton samples obtained from the Ciénaga Grande de Santa Marta, an extensive estuarine system in northern Colombia, yielded adult male and female specimens of an undescribed halicyclopine cyclopid copepod of the genus Halicyclops. 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. Halicyclops gutierrezi 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.

Two new species of Halicyclops are described from plankton samples taken in two localities in the Amazon River mouth area, State of Para, Brazil . Halicyclops lindbergi sp .n . resembles H. hurlberti and H. clarkei from which it differs by a combination of characters in leg 5, the anal pseudoperculum and the caudal rami . The other new species, H. dussarti, is most morphologically similar to H. pilosus, but they are separated by differences in legs 1 and 5 as well as in the ornamentation of the middle caudal setae .
