Original protologue

Endocarp globose, spherical, 3.8–4.4 mm in diameter, ornamented by three longitudinal grooves that begin and end just short of the apex and base. Apical pit shallow, ca. 1.8 mm wide, 43% of the maximum endocarp width, thin walled, single pored, and sharply truncating the endocarp. Three
locules—surficially indicated by longitudinal grooves that connect to weakly sutured septa (fig. 9B6)—are strongly curved. Basal pit prominent, ca. 0.6 mm in diameter.

Etymology

Named for the three longitudinal grooves on its endocarp from the Latin prefix tri- (three) and adjective sulcata (grooved).
