Classification: Coccolithophores -> Isochrysidales -> Noelaerhabdaceae -> Reticulofenestra -> R. umbilicus group -> Reticulofenestra wadeae
Sister taxa: R. umbilicus, R. dictyoda, R. hillae, R. hampdenensis, R. hesslandii, R. moorei, R. circus, R. circus var. lata, R. wadeae, R. maceria Shafik 1989, R. oamaruensis,

Taxonomy:

Citation: Reticulofenestra wadeae Bown, 2005
Rank: Species
Notes & discussion: Subcircular outline distinguishes this species from most other reticulofenestrids and the central area is wider than Cyclicargolithus.

Distinguishing features: Medium to large subcircular Reticulofenestra with wide central area (= to width of shields) and no visible net or grill in light microscope.
