Original description: [Lucas-Clark, 1984]:

Holotype. Plate 3 figs. 1, 2, 4. Sample PL4436, Locality 6, Covelo, California, Slide AS 36, coordinates 41.5 X 1 10.7.
Description. Skolochorate apiculocavate cysts with sub-spherical to ovoid central body and a total of 25 discrete hollow processes (three on operculum). Periphragm smooth or with slight undulations, Endophragm ornament, which is finely granular, visible only beneath processes.
Processes cylindrical or goblet-shaped; narrow and circular at the base, tips slightly flared or constricted, generally thickened into a rim; shafts circular to oval in cross-section, commonly expanded about one-fourth of length from tip into goblet shape. Processes represent B, Ci, 1u, 1i, 2-6, ai, au, b-e, fi, lu, II-Vi, X, Y, and Z: processes no more than one per paraplate. Processes open. Cingular, sulcal, and apical processes generally more slender than pre- and postcingulars. Archeopyle apical;
operculum adnate ventrally.
Dimensions. Holotype: maximum diameter 52.2 μm, central body 30.3 μm X 24.2 μm, process length ca. 11 μm. Paratype #1: maximum diameter 53 μm, central body 35 μm X 28 μm, process length ca. 10 μm. Paratype #2: central body length 17 μm, process length ca. 8 μm. Range: maximum diameter 45-55 μm. Specimens measured, 8.
Remarks. Detailed comparisons of the morphological features of this species to others assigned to Litosphaeridium are made in the first part of this paper. Its most obvious distinctions are the goblet shaped processes and limited number of cingular processes (only 6).
Occurrence. Locality 6, Elk Creek Melange, Franciscan complex, northern California. Upper Albian-Cenomanian.
