John Hollier, Edmund Schiller & Nesrine Akkari, 2017, An annotated list of the Diplopoda described by Aloïs Humbert alone and with Henri de Saussure, and the Diplopoda from Saussure’s Mexico expedition, Revue suisse de Zoologie 124 (2), pp. 203-224 : 214

mexicanus Humbert & Saussure, 1869a: 156 [ Platydesmus ].

Mexico, Cordillera orientalis. Unspecified series.

Saussure & Humbert (1872) gave a more detailed redescription, giving the type locality “Sierra de Agua” and mentioning nine ♂ specimens. The MHNG collection has four card-mounted specimens. The two largest specimens, mounted on the same card, have the locality “Mexiq.” written on the identification label, and “A.” written at the lower right corner of the card. Another specimen has an identification label without locality and the last specimen has no labels but “A.” written in the lower right corner of the card. There is no reason to suppose that they are not all syntypes. There is also a ♀ syntype in the NHMW (Inventory number 2099, Acquisition number 1866.I.D)
