摘要：
Microcancilla jonasi new species is described from deep waters off northeastern Brazil. The genus Microcancilla Dall, 1924, had not previously been recorded in Brazilian waters. Specimens were collected from sediment dredged as part of the REVIZEE program (Assessment of the Sustainable Potential of Living Resources in the Exclusive Economic Zone) (hiring prospecting work on the continental slope off the state of Pernambuco at depths of 425 to 690 meters. The present study reveals that these specimens present affinities to the species Microcancilla microscopica (Dall, 1889), Which differs from the new species, among other features, by having strong spiral sculpture between sigmoid axial ribs. In addition, a lectotype for Cancellaria microscopica Dall, 1889, is designated herein.
