Finding the land snail Triodopsis hopetenensis, the Magnolia Threetooth, in NYC

On Friday March 12, my iNat friend @steven-cyclist drove us to Shirley Chisholm State Park in Brooklyn, at the north end of Jamaica Bay.

To my surprise I found a lot of empty shells and live individuals of the polygyrid species Triodopsis hopetonensis, identified for me by Harry G. Lee of Jacksonville, Florida.

Cool!

This species has apparently never been recorded before from New York State, so I am writing an article about this discovery for American Conchologist magazine.

The first four images here are of dead empty shells from grassland. The other five images are of live snails that were sheltering under small rocks beside a gravel pathway in the State Park.

Thanks Robin, the shells are very cute with those fancy apertures, aren't they!

And thanks Daniel, I hope I can get out more often to places like this that are a bit further away than I can easily go. I am lucky that I have two friends who have access to a car sometimes.
