Abstract
The history surrounding the identity of Cletocamptus albuquerquensis (Herrick, 1894) and C. dominicanus Kiefer, 1934 is very complex. This complexity has been exacerbated by incomplete, and in some cases erroneous, original descriptions of these two species. Also, new records from other locations did not describe the significant characters needed to clearly delineate them. This led several authors to consider C. dominicanus as a synonym of C. albuquerquensis, among other taxonomical considerations regarding, for example, the status of Marshia brevicaudata Herrick, 1894. Inspection of biological material from Saskatchewan (southern Canada), Wyoming (central US), Trinidad and Tobago, and the British Virgin Islands, identified by other researchers as C. albuquerquensis, as well as of newly collected material from Great Salt Lake (Utah, central US), Puerto Rico, Culebra Island, Vieques Island, St. John Island (US Virgin Islands), San Salvador (Bahamas), and Santa Marta (Colombia), revealed that C. albuquerquensis and C. dominicanus are distinct and identifiable species, distributed in a more restricted area than previously thought. Additionally, we describe a new species, C. tainoi sp. nov., from St. John Island (US Virgin Islands), and we propose another new species, C. chappuisi sp. nov., for two males from Bonaire previously identified as C. albuquerquensis. Finally, we give some observations on tube-pore-like structures, previously overlooked, on the endopod of the male leg three.
Highlights
The systematic position of the genus Cletocamptus Schmankewitsch, 1875 (Harpacticoida: Canthocamptidae Brady, 1880) is still controversial
Most species have been recorded at low altitude (0 – 600 m a.s.l.) e.g., C. nudus Gómez, 2005, C. sinaloensis Gómez, Fleeger, Rocha-Olivares & Foltz, 2004, C. samariensis Fuentes-Reinés, Zoppi de Roa & Torres, 2015 (GÓMEZ et al, 2005; FUENTES-REINÉS et al, 2015), but some of them are known to
The aim of this paper is to report the first record of C. sinaloensis for Colombia and to present a brief description of this material in order to support the identification of the newly found material
Summary
The systematic position of the genus Cletocamptus Schmankewitsch, 1875 (Harpacticoida: Canthocamptidae Brady, 1880) is still controversial. Most species have been recorded at low altitude (0 – 600 m a.s.l.) e.g., C. nudus Gómez, 2005, C. sinaloensis Gómez, Fleeger, Rocha-Olivares & Foltz, 2004, C. samariensis Fuentes-Reinés, Zoppi de Roa & Torres, 2015 (GÓMEZ et al, 2005; FUENTES-REINÉS et al, 2015), but some of them are known to. Species of Cletocamptus from America have been found in Argentina, Brazil, Chile, Colombia, Mexico and the United States (FLEEGER, 1980; MIELKE, 2000; GÓMEZ, 2005; GÓMEZ & GEE, 2009; FUENTES-REINÉS & SUÁREZ-MORALES, 2014; GÓMEZ & MORALES-SERNA, 2014; FUENTES-REINÉS et al, 2015; GÓMEZ et al, 2017). The copepod fauna from Colombia has received little attention despite the number of fresh, marine and brackish systems in both the Atlantic and Pacific coasts of the country and additional new species and records of harpacticoids are expected to be found in future studies
