Tosatrochus

The thick, imperforate or very narrowly perforate shell has a conic-elongated shape.

The 9 whorls are convex, spirally lirate (the lirae unequal) and longitudinally nodose-costate, the nodules more prominent below.

The angulated body whorl is depressed beneath the sutures and nodulous at the periphery.

The columella is subangular, concave, strongly truncate at base, with a short callus over the umbilicus.

[4] This species occurs in the Indo-West Pacific and off the Philippines and South Australia.
