Taxonomy:

Citation: Lacunolithus Bown 1993

Rank: Genus

Type species: Lacunolithus tholiformis Bown, 1993

Taxonomic discussion: Lacunolithus Bown (1993) is a junior homonym of Lacunolithus Lyul'eva (1989) so either a replacement name is needed or the one described species should be recombined in another genus. [JRY]
