The leptostracan Dahlella caldariensis, new genus, new species, is common at hydrothermal vents on the Galapagos spreading center and the East Pacific Rise at 13°N and 21°N (2,450-2,620 m depth). It was found in the throat of vent openings and clumps of mussels and vestimentiferans. The genus is most strikingly recognized by its elongate, dentate eyestalk. Living leptostracans are realigned among two families, Nebaliopsidae, new family, and Nebaliidae, new combination, which are diagnosed herein.
