Euconulus trochulus (Reinhardt, 1883)
Common name: Silk Hive
Width: 2-3 mm
Height: 2-3 mm
The shell of Euconulus trochulus is more angular overall than others in its genus. The top of the shell comes almost to a point and the base is relatively flat. A deep suture and the sharp keel of the outer whorl, which is also apparent in the inner whorls, create the impression of a terraced surface (Pilsbry, 1946). The aperture is narrow and has a trapezoidal shape. Close radial striae and very fine spiral lirae compose the microsculpture of the shell.
This species is usually found in moist leaf litter (Hubricht, 1985).
Euconulus trochulus has also been known as Conulus chersinus trochulus, C. trochulus, and Euconulus chersinus trochulus.
Euconulus trochulus is widespread throughout the southeastern United States and parts of the Midwest (Hubricht, 1985). It is near its northern limit in Virginia, where it is only reported from a few southern counties
