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 : 217

simillimus Humbert & Saussure, 1869a: 150 [ Polydesmus (Fontaria) ].

Mexico temperata. Unspecified series (more than one individual).

Saussure & Humbert (1872) gave a more detailed redescription, and mentioned the locality “Cordillère orientale; Santa Cruz près Orizaba”, noting that the species was found under the bark of trees. The MHNG collection has six card-mounted specimens under the name Fontaria simillima . Two ♂ specimens mounted on the same card have the label “5d” while four smaller specimens, all mounted on the same card, have the label “5c”. There is also a glass vial with a dry pair of gonopods secured by a pin through the cork stopper. Hoffman (1966: 16) designated the smaller ♂ (mounted legsup) as lectotype, as indicated by the word “Lectotype” handwritten on the card at the rear of the specimen.
