AbstractDesmotersialevinae gen. n.,sp.n.isproposed,basedonmaterialfoundinbathyaloxygenminimumzonesediments off thecoastofPeru. Desmotersia closely resembles Richtersia in theanimals’generalappearanceandinspiny ornamentationofthebodycuticle,butclearlydiffersinstomastructureandbythepresenceofadorsaltooth. The systematicpositionsofthetwogeneraarediscussed,since Desmotersia apparently forms a link between Selachinematidae and Desmodoridae. Desmotersia levinae is characterized by a variety of spiny ornamentations anteriorly formed by bipartite spines arranged into a fin-like picket fence,by a head with anasymmetrical cephalic capsule, presence of two closely spaced ventral longitudinal rows of copulatory thorns,and by 2–4 ventral thorns in mid-tail positions on the male. The interaction between the new species and its habitat is discussed.
