Brizalina subreticulata Jones, 1994, p. 59 View in CoL , fig. 30–31.

Description: The test wall is calcareous and microperforate. The test is small, broad, biserial, triangular-ovoid in shape and elliptical in cross-section. The test is less than twice as long as it is wide. Irregular, reticulate, interwoven costae cover the entire test, giving a reticulate appearance to the test. The aperture is slit-like and situated at the base of the terminal chamber.

Life strategy: This species is infaunal ( Drinia et al., 2007), unattached and prefers muddy sediments under dysoxic conditions ( Kaiho, 1994). The bathymetric distribution of this species is recorded to be from the inner shelf to slope ( Murray, 2006).

Remarks: The relative abundance is generally low, comprising trace components (<1%) in the samples of core 2670. The tests are small, measuring 0.2 mm in width and 0.35 mm in length.

Global stratigraphic range: This species occurs from the Oligocene to Recent ( Fenero et al., 2012).

Regional occurrence: Bolivina reticulata is recorded in middle Miocene sediments on the Namibian outer continental shelf, south of the Kunene River mouth (this study).
