Dicyemennea eltanini sp. n. (Mesozoa: Dicyemidae) from Antarctic Waters

Dicyemennea eltanini sp. n. is described from an unidentified octopod host collected on the South Scotia Ridge, SE of South Orkney Islands. The 10 largest nematogens measured 961 to 1,367 µ in length; the four largest rhombogens were 772 to 1,789 µ in length. The peripheral cell number of vermiform...

Description
Summary:Dicyemennea eltanini sp. n. is described from an unidentified octopod host collected on the South Scotia Ridge, SE of South Orkney Islands. The 10 largest nematogens measured 961 to 1,367 µ in length; the four largest rhombogens were 772 to 1,789 µ in length. The peripheral cell number of vermiform stages is 23; the axial cell extends forward to the propolar cells. Infusoriform larvae are about 30 µ long (excluding cilia); they possess refringent bodies which are apparently solid, and they are composed of 37 cells (33 somatic, 4 germinal). This is the first dicyemid described from Antarctic waters.
