Plankton samples from a small temporal pond in Puebloviejo, Magdalena Department, yielded two species of the genus Cletocamptus Schmankewitsch 1875: Cletocamptus samariensis sp. nov and Cletocamptus nudus Gomez,2005. The new species is closely related to C. schmidti Mielke, 2000 and C. nudus Gomez, 2005 based on the armature formula of P1-P4, but can be separated from these two congeners by a combination of characters including: 1) anal operculum, 2) antennal exopod, 3) anal somite and 4) setation of the fifth leg of female and male. The male of C. nudus Gomez 2005 is described for the first time.
