A new mesophotic branching coral species of Psammocora from the Mariana Islands Archipelago (Cnidaria: Scleractinia: Psammocoridae)

Randall RH


A new mesophotic zoozanthellate coral species, Psammocora eldredgei, sp. nov. (Scler - actinia), is described as new to science. It has small 2 to 5 mm diameter branches arranged in an open arborescent manner. The calices are small, ranging from 1.40 to 2.41 mm in diameter with 6 to 9 thick closely spaced granulated septa that reach a central fossa and small styliform columella. The species is represented by 516 specimens collected from 16 stations between 33 and 200 m depth from deep banks and island forereef slope habitats along the fore-arc of the Mariana Island Archipelago. The species is named Psammocora eldredgei in honor of the late marine biologist Dr. Lucius. G. Eldredge, who was my thesis chairman in 1971, and a colleague during his long tenure at the University of Guam Marine Laboratory where we worked together on many research projects.
