New deep bryozoan species from the Southwestern Atlantic: shedding light in the dark
The present paper reports on 22 bryozoan species collected from 25 localities on the Southwestern Atlantic continental shelf and slope by the Instituto Español de Oceanografía vessel RV Miguel Oliver (2008–2010). Two new genera, Amynaskolia n. gen. and Biconcavus n. gen., and twenty new cheilostome...
