Three new buccinid species (gastropoda : neogastropoda) from chilean deep-water, including one from a methane seep

Three deep water species from off the Chilean coast are described as new. Aeneator prognaviter sp. nov. (off Antofagasta) is compared with A. loisae Rehder, 1971 and A. castillai McLean & Andrade, 1982. The peculiar Aeneator portentosus sp. nov. (off Coquimbo) has the generic placement based on conchological characteristics and is compared with Americominella duartei Klappenbach & Ureta, 1972. Kryptos explorator sp. nov. (off Concepcion) is compared with K koehleri (Locard, 1896), the generic placement based on conchological characteristics (protoconch and slightly broader peripheral spiral interspace) and radular morphology. Kryptos explorator sp. nov. has been collected at a recently discovered methane seep area off Concepcion (similar to 36 degrees S), but its degree of association to seep fauna is still uncertain.
