Tubbreva is a genus of taxonomic family of minute sea snails, marine gastropod molluscs belonging to the family Cingulopsidae.[1] First described by Winston Ponder in 1965, the genus is known to occur in the Pacific Ocean and the Mediterranean Sea.
Description
[edit]In the original description, Ponder described the genus as below:
Shell very similar to Rufodardanula, though often more elongate and imperforate.
Operculum: Similar to that of R. (R.) spadix, but has a very short, almost rudimentary peg, which is only slightly thickened, and has a more expanded columella edge.
Radula: Very minute or absent as it has defied ail attempts at mounting. Until anatomical and radula characters are known, Tubbreva is considered to be subgeneric to Rufodardanula.[2]
Members of the genus have minute shells, are elongately conical, thin and smooth. Tubbreva has almost straight non-umbilicate columella with a weak bulge, and a thin, oval operculum that lacks an internal ridge. Additionally, the operculum has a very short peg that does not project beyond the margin and no radula.[3][4]
Taxonomy
[edit]Tubbreva was first described by Winston Ponder in 1965 as a subgenus of Rufodardanula. Ponder named Tubbreva exigua as the type species.[2] In 1980, the taxon was raised to genus level by Ponder and E. K. Yoo.[3] Due to the genus' distribution in the Mediterranean and the Pacific, Ponder suggested that the genus was found in the prehistoric Tethys Ocean, before the ocean was spit apart.[5]
Phylogenetic analysis places Tubbreva within the Cingulopsoidea superfamily, being more closely related to Eatonina than genera such as Skenella, Eatoniella or Crassitoniella.[6]
Distribution
[edit]Tubbreva is found in the waters of the Pacific including Australia and New Zealand,[3] Japan,[7] and the Mediterranean Sea.[8] Fossils of the Chattian species T. chattica have been found near Saint-Paul-lès-Dax in southwestern France.[9]
