Abstract

Two new species of polychaetous annelids Prionospio unilamellata sp. nov. and Laonice asaccata sp. nov. (Spionidae) are described from samples collected at Mid-Atlantic hydrothermal vent fields close to the Azores Triple Junction and in the Snake Pit vent field. These two species are important components of the communities associated with active venting. Prionospio unilamellata differs from all other Prionospio species in the form of anterior notopodial lamellae. Laonice asaccata differs from other Laonice species by lacking interparapodial pouches.
