Clathrina cerebrum sensu Borojević, 1967

Borojević (1967: 192) reported this Mediterranean species, originally described by Haeckel (1872: 54, as Ascaltis), from Kwazulu Natal, Eastern South Africa. The Mediterranean species has been reassigned to Borojevia by Klautau et al. 2016. Like the Mediterranean B. cerebrum, Borojević’s specimen has tripods of 60–100 x 20–32 µm, unlike the three Borojevia species described above. Like these three species the South African specimen has spined apical actines of the tetractines. This record likely represents an additional undescribed species of Borojevia .
