- Abstract
A new species of talitrid amphipod, Chelorchestia colombiensis sp. nov., is described from the central zone of the Pacific coast of Colombia. Specimens examined were collected on the intertidal rocky shore associated with encrusting and filamentous algae. This new species of Chelorchestia differs from the other four described species, C. costaricana (Stebbing, 1906), C. vaggala (Bowman, 1977), C. darwinii (Muller, 1864), and C. forceps Smith & Heard, 2001 principally by the presence of well developed lobes on the ischium of the second gnathopod in males, as well as by the presence of two well developed rounded humps on the palm of the second gnathopod in males. Furthermore, variation was found in the length of antenna 2, uropod 1, uropod 2, and telson.
