    Taxonomy from Parsley & Zhao 2006.

    Diagnosis for the genus and species from Parsley & Zhao 2006, p. 1065: "Gogiid with at least three series of near equidimensional, essentially hexagonal plates developed directly under apical ambulacrum and two series of elongated transitional plates between them and first holdfast plates in small juveniles (TH <3 mm). Larger juveniles and mature specimens irregularly plated because of subsequent plate intercalation. Thecal plates comprising basal part of theca irregular and similar to plates of holdfast except that they have sutural pores. Ambulacral area restricted to upper thecal surface and arranged in 2-1-2 pattern except in early juveniles where pattern is 2-2. Depending on ontogenetic stage, straight brachioles number 4, 5, 10, or 15. Cover plates unusually tall. Holdfast variable in length and composed of numerous bossed platelets. Attachment disk slightly expanded and composed of several layers of small platelets."
