Original Description
Skeleton flat, three-rayed. Each ray has a latticed cortical shell surrounding a long protruding central spine which bears several pairs of opposite branches in successively perpendicular planes. Microsphere five-gated, eccentric, migrated in the antapical direction and heteropolar, with heptagonal basal gates, and the antapical gate much larger than the lateral ones. Apart from the two long RL spines disposed along the rays, of which one is apical, the microsphere has four short RBu and four short RBl spines obliquely directed in pairs on both sides of the central part of shell.

Etymology: From the Latin tri = three, and mani-cula = small hand. Feminine gender.
