1977 Bolivina panayensis McCulloch : p. 257, pl. 105, fig. 15.

Remarks. The overall morphology of this species is similar to Brizalina sphathula ( Williamson, 1858) and Brizalina argentea ( Cushman, 1926a) , but it is different from the latter species by possessing clear costae. This form also resembles Brizalina subaenariensis ( Cushman, 1922) , but differs by possessing more costae and chambers and being more elongated.
