Original Description
Small shell nut-shaped, having but little mid-vertical stricture save that the coryphal face is slightly indented and the 2 similar, opposite lobes are little inflated; pores rather few (approximately 20 or less in each lobe on 1 face), distinctly separated, uniformly circular, and of nearly the same size and without regular order; surface not pronouncedly rough, but the pores are set into polygonal areas, and these areas bounded by a raised framework so that the general surface is blobby; narrow, conical apical horn terminal, mid-coryphal, rather long (0.3 altitude of shell), with sharp tip, and with simple base; great-circle strong and prismatic; 3 feet, 1 caudal and 2 paired pectoral, divergent, generally straight, conical, with very sharp tips, simple bases, and thick shafts; interradii mildly arched, smooth; basal view not obtained.

Size: Total length 102µm, of horn 34µm, of feet 49µm.

Etymology: No information given

Extra details from original publication
Distinguishing features: Tripospyris sacramentoensis n. sp. is a neat, tiny species differing from clathrata Clark and Campbell (1942) in having fewer pores, more compact form, and rougher surface. Its feet are less divergent, and the lobes less swollen than in dubia Clark and Ca

Editors' Notes
The authors here questionably listTripospyris sacramentoensis under the subgeneric name Tripospyrella and include the subgeneric name in the species name.[comment from RadWorld database]
