Type locality. [Guatemala] "sylvas Petenensis". Label. "foret de Dolores", taxon label in Morelet's handwriting. Dimensions. "Longit. 11 - Diam. 9 [mm]". Figured specimen H 8.26, D 6.79, W 4.3. Type material. NHMUK 1893.2.4.1128-1129, two syntypes (Morelet coll.). Remarks. Morelet did not state on how many specimens his description was based. On the board on which the labels are glued has been written in a later hand "Type largest / Test. Noviss. No. 101". The locality on the label probably refers to the village of Dolores, Peten , Guatemala, which is thus the exact type locality. The current systematic position follows Thompson (2011 : 130). Current systematic position. Simpulopsidae , Simpulopsis (Simpulopsis) simula (Morelet, 1851).
