Coloniconcha

Photo of the day (11): Coloniconcha

Jozef Grego sent me a photograph, which he had received from Pedro Genaro, a naturalist from Dominican Republic and an excellent photographer. As I don't want to infringe on his copyrights, I have made a direct link. And you absolutely should do, as it is really a very artistic picture and a very interesting blog!
Coloniconcha prima
In fact it is Coloniaconcha prima Pilsbry, 1932 and when I received the first picture made by Eladio Fernandez, another excellent photographer and naturalist from the same country, it looked so strikingly like a Gaeotis (occurring on Puerto Rico), that I'm still not decided yet on the basis of the pictures alone. This is a puzzle that remains to be solved...
