This is one of the largest of a group of several small species, apparently confined to the West Indies, of which nana, hereby assigned to the same genus, is the only one hitherto described. Nana was placed by Suffrian under Heteraspis of LeConte. LeConte afterwards, discovering the earlier use of the name Heteraspis by Blanchard for an oriental genus, replaced it by the name Graphops. Nana cannot be referred to LeConte's genus Graphops on account of the lack of any supraorbital sulcus on the head, and Clavreau in Coleoptorum Catalogus has referred it to the genus Glyptoscelis. The North American species of Glyptoscelis and the Venezuelan G. aeneipennis, which also extends to Trinidad and Grenada, are much larger insects, and in habitus bear little resemblance to the small West Indian species. Neither does the West Indian group resemble the small southwestern genus which Horn as referred to the Mediterranean genus Colaspidea. The prothorax is differently shaped from that of either Colaspidea or Glyptoscelis. It is nearly twice as broad as long, much wider than in typical Glyptoscelis, with lateral margins brodly arcuate, and not contracted at the base, and the elytra are wider and more oval, thus producing a more oval and less oblong shaped insect.
