This is a relatively new species of Acanthopyge that does not yet have a formal description. It is most similar to Acanthopyge haueri, but has a relatively narrower thorax and pygidium and relatively longer spines. A. haueri has long since been quarried out and real specimens are only made available at rare intervals and at very high cost when old collections are sold off.
This specimen is relatively small for the species, but unlike most specimens of the species it is not a molt -- the genal spines were firmly attached. The shell quality is also exceptional, and the prep is excellent.
