New Radiolarian Species of the Genus Carpocanium Ehrenberg, 1847, emend. nov. in the Surface Sediments of the Emperor Seamount Chain, Pacific Ocean

The diversity of radiolarian species of the family Carpocaniidae Haeckel, 1881, emend. Riedel, 1967, from the surface sediments of the Emperor Seamount Chain (Nintoku, Jingū, Ojin, Koko and Yuryaku guyots) is analyzed. Five new species of the genus Carpocanium Ehrenberg, 1847, emend. nov.: C. rotundum sp. nov., C. fragaria sp. nov., C. alabastrum sp. nov., C. tulipa sp. nov., and C. fungus sp. nov. are described. The identification of the new species is based on their morphology, which differs from that of other species of the genus Carpocanium. It is proposed to restore Carpocanarium Haeckel, 1887 to a valid genus, and transfer it back into the family Carpocaniidae, based on the overall correspondence of its morphology to the diagnosis of this family.
