Abstract
Fieldwork in the Bijagos Islands, Guinea-Bissau, in 2023, yielded specimens of a species of Palaemon new to science. The specimens are herein described, illustrated, and compared with related species. We obtained sequences of the mitochondrial markers 16S and COI, as well as of the nuclear marker H3 of the Palaemon specimens from the Bijagos Islands. We used these sequences to analyse the phylogenetic position of the new species within the genus Palaemon. The new species is most closely related to P. floridanus and P. northropi from the tropical western Atlantic.
