Minuscula

The teeth of Lucilla inermis (left) and Hawaiia minuscula (right). ❋ AYDIN (2007)

In contrast, this is what Hubricht4 said about H. minuscula: A species of bare ground. ❋ AYDIN (2007)

As I was about to give up, Tim Pearce came to the rescue and pointed out that the teeth on the radulae of H. minuscula and L. inermis have different shapes, the most significant being the shapes of the marginal teeth, blade-like in minuscula but serrated in inermis see the drawings below. ❋ AYDIN (2007)

I think the resemblance is a bit stronger than "somewhat", for after I examined the drawings in Pilsbry, I had no idea how tell if the shells I had were minuscula or inermis. ❋ AYDIN (2007)

According to Pilsbry2 the shells of the species in the subgenus Hebetodiscus "resemble Hawaiia minuscula somewhat, but are smoother and more depressed". ❋ AYDIN (2007)

Frank C. Baker3 gave the "most common" habitat of H. minuscula in Illinois as "woodlands of oak, hickory and sycamore". ❋ AYDIN (2007)

My specimens also have smooth shells like those of minuscula. ❋ AYDIN (2007)
