Corpus, longitudinally elongate oval, often not clearly visable. Exoexine of cappa about 1-2 thick. Saccus exoexine about 4 thick and densely intrareticulate. This species diagnosis is similar to that of Protohaploxypinus microcorpus , except for a somewhat coarser saccus infrareticulum and a overall thicker exoexine. This sand is Lower Permian - Leonard in age and presently being described by Lawrence Skelton of the Kansas Geological Survey in Wichita, Kansas.
Spores belong to the plant kingdom.
