Abstract
Combined faunistic and genetic studies in the marine Ekamako Cave at the southern coast of Nuku Hiva, Marquesas, in the central Pacific, yielded Heteromysis (Olivemysis) ekamako as a new species. This taxon differs from its congeners by a specific combination of morphological characters: flagellate, modified spines dorsally on each of the three segments of the antennular peduncle, a large smooth spine at the tip of only the second male pleopod, series of small flagellate spines along the oblique terminal margin of only the third and fourth male pleopods, and by 2–3 simple spines medially near the statocyst on the endopods of uropods. Although abundant at the entrance of Ekamako Cave, it has not been observed in nine additional submersed marine caves investigated at the Marquesas.

Acknowledgments
First of all, we wish to thank Thierry Pérez for leading Leg 3 of the “Pakaihi I Te Moana” expedition and for the Ekamako Cave dives with one of us (PC). We are also indebted to Xavier “Pipapo” Curvat for showing us the cave, to Laurent Albenga and John Starmer for their hard work underwater, and to the captain and crew of R/V Braveheart. The French Agence des Aires Marines Protégées (AAMP) was the main sponsor and coordinator of this expedition. The Marquesan people are warmly thanked for their spirit and hospitality.
