Resumen:
The present work provides a first description of the zoeal stages of the Caridean prawns Campylonotus
vagans, C. semistriatus and C. capensis Bate, 1888. Zoeal stages one and two were obtained
from plankton catches during several expeditions in the Magellan region and the southwestern
Atlantic Ocean, and first zoeae of C. vagans were confirmed with larvae hatched in a laboratory
culture. Based on the results obtained, we conclude the morphological differences of the presence/
absence of carapace spines, the shape of the somites, the telson and its number of posterolateral
spines to serve as diagnostic features for the determination of campylonotid larvae. Morphological
comparisons with larvae of the Pandalidae, Palaemonidae, and Oplophoridae suggest the
Campylonotidae to be phylogenetically related to the Oplophoridae. Additionally, a key for identifying
the zoeal stages of the Campylonotidae from the southernmost region of America is given in
order to facilitate future ecological and life history studies.
