Ammopemphix Lacustris N.sp. (Foraminiferida) From Lac des Allemands, Louisiana

Abstract

Ammopemphix lacustris, n.sp., is recorded from Lac des Allemands, a fresh to brackish water lake located on the upper deltaic plain of the Mississippi Delta.  The new species is compared to, and differentiated from, other species assigned to this genus.  The relationship of this genus to a homeomorphic Paleozoic genus is discussed.
