abstract = {Molecular analyses have revealed many cryptic species in the oceans, oftentimes permitting small morphological differences to be recognized as diagnosing species, but less commonly leading to consideration of cryptic ecology. Here, based on analyses of three nuclear (ribosomal 18S, 28S and internal transcribed spacer 1 [ITS1]) and two mitochondrial (cytochrome c oxidase subunit I [COI] and ribosomal 16S) DNA sequence markers and fifty-five morphological features, we revise the classification of the enigmatic jellyfish genus Drymonema. We describe a new scyphozoan family, Drymonematidae, elevating the previous subfamily Drymonemidae and correcting its spelling, to accommodate three species: the type species D. dalmatinum from the Mediterranean region, for which we identify a neotype, the western South Atlantic species D. gorgo and the new species D. larsoni from the western Atlantic and Caribbean, which is also described here. This revision emphasizes the remarkable morphological disparity of Drymonematidae from all other scyphomedusae, including allometric growth of the bell margin distal of the rhopalia, an annular zone of tentacles on the subumbrella, and ontogenetic loss of gastric filaments. Anatomical innovations are likely functionally related to predatory specialization on large gelatinous zooplankton, most notably the phylogenetically younger moon jellyfish Aurelia, indicating evolution of the feeding niche in Drymonematidae. This family-level revision contributes to the growing body of evidence that scyphomedusae are far more taxonomically rich, their biogeography a more detailed mosaic, and their phenotypes more nuanced than traditionally thought. Ecological and evolutionary responses to environmental change, past or future, are likely commensurately diverse.}
