These characteristics, combined with its ancient divergence, suggested it had been evolving independently from other Radula species for a very long time. The recognition of Dactyloradula as a separate genus brought the total number of genera in the family Radulaceae to three, alongside Radula and Cladoradula. [3]

The radula (US: / ˈ r æ dʒ ʊ l ə /; pl.: radulae or radulas) [1] is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. [2] It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus .
The species was long classified in the genus Radula within subgenus Cladoradula. In 2022, Renner and colleagues conducted a molecular phylogenetics study that revealed the subgenus Cladoradula represents one of the oldest lineages within the family Radulaceae, having diverged from other members during the late Permian period.

The most common compounds found in Radula species are 3,5-dihydroxy-2-(3-methyl-2-butenyl)bibenzyl and 2-geranyl-3,5-dihydroxybibenzyl, which often form the basic structure for more complex molecules in these plants. [17] Of particular interest is the presence of compounds similar to those found in cannabis (cannabinoids) in some Radula species
