Description

Tosapusia turriformis possesses a medium-sized, thin-walled shell measuring up to 27.15 mm in height, exhibiting a narrowly turriform shape characterized by a high, slightly acuminate spire and an elongate-fusiform outline with a width-to-height ratio of approximately 0.29. The teleoconch consists of 9.5–11 slightly convex whorls, with early whorls shouldered and subcylindrical, transitioning to flattened adapical profiles in later whorls where the convex periphery is shifted abapically. The last adult whorl is strongly convex, comprising about 52% of the total shell height, and is shortly constricted to a short to moderately long, tapering siphonal canal that is widely open, straight, forming a distinct "waist" at the transition with a slightly concave profile. Sutures are deeply impressed and canaliculated on early spire whorls, becoming slightly wavy and less pronounced on later ones. ^{[3] [4]}
