Grantessa glabra Row, 1909


Grantessa glabra Row, 1909 

See Row (1909: 203, pl. 19 figs 5–6, text fig. 4). Discussed above in connection with possible synonymy with Sycettusa stauridia ( Haeckel, 1872)  . The type specimen BMNH 1912.2.1.9 was re-examined by us. It is a small tube with side oscule. It has cortical and atrial triactines much larger (400–700 µm) and diactines and pseudosagittal triactines much thicker (50–90 µm) than Haeckel’s and the above described material. For the time being it is reassigned to Sycettusa glabra  , but redescription is necessary. Burton (1952) reported this species from the Egyptian part of the Gulf of Aqaba without a description.
