Abstract
During several sampling periods in the Northern Adriatic Sea (Mediterranean) from 2003–2010, one species ofPistaand one ofPistellawere found. They were initially identified asPistacf.lornensis(Pearson, 1969), but detailed examination revealed the presence of two new species, one belonging to the genusPistellaHartmann-Schröder, 1996,P. rovignensissp. nov. and one belonging to the genusPista,P. adriaticasp. nov. These two species differ from each other in the structure of the branchiae, shape of lateral lobes and the structure of the anterior thoracic uncini. The two new species are compared with other species ofPistellaandPistacurrently known. The relationship ofPistellaandPistais confusing and a complete revision of the two genera is urgently needed together with other genera characterized by having long-handled thoracic uncini.
