Microgloma sanders & allen, 1973 (nuculanidae) and pristigloma dall, 1900 (pristiglomidae) (pelecypoda) in the campos basin of Brazil

Abstract

As a secondary result of oil prospecting in Brazil, samples from the Campos Basin continental slope became available. In these samples, specimens of the genera Microgloma Sanders & Allen, 1973 and Pristigloma Dall, 1900 were found. Tis contribution provides the southernmost record of the genus Microgloma, the frst record of M. mirmidina (Dautzenberg & Fischer 1897) from the western Atlantic, the descriptions of M. macaron sp. n. and M. nhanduti sp. n. as new species, and the shallowest record of Pristigloma alba Sanders & Allen 1973. © N.P.
