Type species

Iterodonta ammonita View in CoL gen. et sp. nov.

Diagnosis

Shell small (max. diameter ± 1.7 mm), shallowly and symmetrically biconcave; umbilicus very wide; whorls tightly coiled; last adult whorl not descendant. Protoconch initially with traces of close-set spiral threads, later portion with spiral threads and close-set axial riblets producing a fine, reticulate sculpture; teleoconch with fine, close-set, axial riblets; riblets compound, composed of several periostracal lamellae; intervals between riblets with fine, uneven, intermediary axial threads and fine spiral threads. Aperture narrowly and symmetrically lunate; parietal dentition absent; palatal region with 1–3 broad, prosocline, axial ridge-like calluses.

Etymology

From the Latin itero, iteratus: repeat, repeated; and the Greek odontos (ΟΔΟντΟς): tooth; with reference to the episodic deposition and resorption of the palatal dentition. Gender feminine.

Remarks

Iterodonta gen. nov. is distinctive on account of its reticulate protoconch, relatively strong spiral sculpture on the teleoconch and prosocline palatal calluses.
