Abstract

This study is the first report on the monotypic Codonaria cistellula (Fol, 1883) Kofoid & Campbell, 1939 from the North-Eastern Arabian Sea (NEAS), Indian Ocean. The species was recorded at a water temperature of 25–26 °C and a salinity of 36‰, from a depth of 75–100 m in the NEAS. Two morphotypes were encountered from the region, yet the lorica opening diameter (LOD) remained within a narrow range of 46–50 µm. Moreover, as the original description lacks information on LOD, the circumscription of the species is difficult due to the lorica polymorphism, warranting further genetic analyses.
