GENUS FUSULCULUS BOUCHET & VERMEIJ, 1998 (1)

Type species: Fusulculus crenatus Bouchet & Vermeij, 1998 ; OD.

Remarks: The anatomy of Fusulculus crenatus (own observations) is similar to that of Benthobia spp. , especially the anterior foregut. The mid-oesophagus is glandular, as in Benthobia , although the glandular epithelium is more pronounced in the former. The synapomorphy is the presence of a single accessory salivary gland, terminating in a very large muscular bulb. Similarly, in both genera, the anteriormost part of the osphradium lacks lamellae on the left side.
