The most authoritative publication addressing these three taxa is:

​

Vervaet,  F.L.J., 2018. The living Olividae species as described by Pierre-Louis Duclos. Vita Malacologica 17: 1-111.

 

Almost all treatments of O. dealbata and O. monilifera prior to Vervaet should be considered suspect.

 

Original description (from Vervaet): O. Testâ ovato-cylindraceâ, albâ, punctatâ tribus parvis imaginibus fulvis in dorsum; spirâ acutâ, elongatâ.

 

OLIVE MIETTE. Très-petite espèce à fond blanc, ayant trois rangs de petites maculatures fauves, dont le supérieur continu jusqu’ à la fin du premier tour de la spire, laquelle prend environ moitié de la coquille; bord columellaire légèrement plissé en concave. Longueur, 8 millimètres. Habite les Antilles. Ma collection. Type locality. — “Les Antilles” [Greater Antilles and Lesser Antilles].

 

Vervaet examined a syntype and specimens from numerous Caribbean locations, but not Florida.  Despite numerous authors reporting the synonyms O. dealbata and O. monilifera as present in Florida, I have not been able to confirm any such valid specimens found in Florida.  In a Conch-L discussion during April 2017 regarding this issue, Harry Lee1 commented, “The FL record for O. dealbata appears to be based on Olsson2 (1956: 185; pl. 15, figs. 6, 6a, 6b), who identifies a dumpy shell with the Reeve taxon, a clearly erroneous diagnosis.”  In private correspondence 3/22/22 Harry confirmed “I haven't seen O. mica in FL.”
