Final Epithet
Blackites spinosus (Deflandre & Fert, 1954) Hay & Towe, 1962

Discolithus spinosus Deflandre & Fert, 1954


The holotype is the poorly illustrated base of Blackites Hay & Towe (1962) but difficult to relate to any known species.

The species of Blackites spinula (Levin, 1965) Varol, n. comb. was erroneously assigned to Blackites spinosus in the publications.
