Endictya hendeyi E. Hemphill-Haley sp. nov. is described from Recent and Quaternary, estuarine and marine deposits along the west coast of the United States. This taxon is distinguished by its 1) consistently small valves; 2) areolae of uniform size on the valve face in linear tangential rows; 3) prominent, external spatulate extensions of the rimoportulae at the valve face/mantle junction; 4) externally projecting hyaline rim or flange at the interior edge of the mantle; and 5) discontinuous pattern of pores on the basal siliceous layer. The new species is compared to the generitype, E. oceanica Ehrenberg, as well as E. minor A. Schmidt and E. margaritifera A. Mann.
