toltecus Saussure, 1859a: 322 [ Polydesmus (Fontaria) ].

Cordova au Mexique. Unspecifed series.

Saussure (1860) gave a more detailed redescription of both sexes, but indicated that the original description was based only on the ♀. The ♂ description could have been based on the specimen(s) that furnished the description of P. mayus Saussure 1859a , which he had placed in the synonymy of P. toltecus (Saussure, 1860: 325) . The MHNG collection has parts of what appear to be one ♂ and one ♀ in alcohol under the name Polydesmus toltecus . The fragments are separated in five vials in the same jar. The ♀ specimen, which has been transferred from the dry collection, is labelled “Cordova, Mexique” and is probably a syntype of P. toltecus . The ♂ is unlabeled and could be a syntype of P. mayus .
