Strobilops aeneus Pilsbry, 1926

Common name: Bronze Pinecone

Height: 1.5 - 2.0 mm
Whorls: 6

The shell of this species is dark reddish-brown and is covered with curved radial ridges. The periphery of shells in this genus is generally rounded, but on S. aeneus it is a bit angular. The pattern of the lamellae, as seen through the base, is alternating short-long-short-long. The aperture is wider than it is tall, with a bit of a reflected lip. The shell sculpture is somewhat smoother on the base, which is narrowly umbilicate.

Strobilops aeneus is found upon old logs and in leaf litter, sometimes with S. labyrinthicus. In Tennessee this species was on flatter, drier, and more acid sites, and absent from wet or very rich sites (Coney et al, 1982).

Synonyms for S. aeneus are Strobila labyrinthica, Strobilops aenea, S. labyrinthica, and S. l. strebeli.

This snail ranges widely through the middle and eastern parts of the US, though it is sparse in the north and rare in New England (Hubricht, 1985). It is spread throughout most of Virginia.
