New species discovered using museum’s online collection data
Introducing Bourciera ovata
In the summer of 2020 — the first year of the pandemic — a team of European scientists began compiling a checklist of known terrestrial and fresh water mollusks of mainland Ecuador. The effort included occurrences recorded in past scientific reports or literature, museum datasets available online, and verified observations from citizen science projects like iNaturalist.
In reviewing our records, one of the scientists, Marijn Roosen of the Natural History Museum of Rotterdam, noticed some unusual records of a unique land snail in the Andes Mountains. Marijn requested more information about the snails and photographs to confirm their identifications. It turned out that some of the specimens from Puyo, Ecuador represented species previously unknown to researchers, including the newly-named Bourciera ovata.
With high resolution photographs of different aspects of the snail’s shell, Marijn was able to describe it as a new species, demonstrating a greater diversity of Ecuadorian land snails and the importance of having museum collection data accessible, as surely there are many more new species to be discovered. The research was published in September in the journal Folia Malacologica.

Taxonomy changes reflected in new specimen organization
The introduction of Bourciera ovata is just one example of how what scientists know about species and their taxonomy continues to develop. While working from home during the pandemic in 2020, Collections Manager Alex Kittle began reorganizing the mollusk collection based on updated information and species names, and later moved the actual specimens to reflect these changes. Information about our entire mollusk collection is now publicly available on the Symbiota portal, InvertEBase. Our collection profile shows 233,603 records are available online, representing 500 families and 15,658 species; 32% are georeferenced to specific locations.
