Other Notes
García-Machado et al. (2011) showed three clades of Lucifuga in Cuba, with the L. dentata clade being the most diverse and containing L. dentata, L. simile, and two other lineages that are likely undescribed. The sister lineage to L. dentata is one of the undescribed species (L. sp.1) and is found only in the Matanzas region of Cuba. This clade seems to have palatine teeth while the L. subterranea clade lacks palatine teeth.
