Abstract

Caprellina longicollis (Nicolet, 1849) is redescribed and e gured in detail based on specimens newly collected from Coquimbo, central-northern Chile, which represents the northernmost record of the species. The dominant posture observed for this species in clinging behaviour on its substrate was the “ upright posture” . The combination of weak swimming setae on antenna 2 and the long gnathopod 2 basis suggests a predatory mode of life. A key to the species of the genus Caprellina is here included.
